    Just. I come out with an idea on Car Braking System. I see alot of accident due to the failure of the brakes either front or back brake. So i suggest that the braking system need to be improve. But i not sure where i can start to analyst which part i need to improve.
    Well. My final Year Project in On the way now. I wanted to stick with this idea.

    I thinking of the brake system - fluid compression to the clamp to stop the disk or drum to decelerate the speed of the car, Change to the clamp into a magnetic field. Its it an good idea? Coz the flow of fluid may cause the tube adding some air accidentally and sometimes the tube occur leakage.

    But if it does change to magnetic field to decelerate the disk or drum, i guess is more better than that rite? what u all guess suggest.

    BTW do this Magnectic Braking system available now?

    Yes, there is magnetic braking. It would be a good topic to explore & refine. It currently is not used in automobiles due to cost/reliabilty issues and they are not effective at slow speeds, however over time that could change. the are called Eddy current brakes and primarily used on trains and roller coasters. There is no friction involved or mechanical contact. Electromagnetic brakes are like a hybrid in that they use magnetic force to press the pads against the rotor. This would be the variety to adapt to personal vehicles.

    Yes thats correct.. But in cars we have got ABS( Anti lock Braking System ). Thats the one we commonly used. Actually people forgotten the importance of brakes they just care about the power and mileage figures only. Remember Pirreli's Tag line " Power is nothing with out control".. well keep going maxz.. good luck :clap:

    Hey man.. This could be the present generation braking system.. But the next generation in one way or other is going to use the EWB(electronic wedge brakes).. It is more safe and its efficiency is greater than 45% compared to the conventional 33% of disk brakes..

    Ya man~!!! Tats the point. I had doing some research about the magnetic braking system which is only applied on trains and roller coaster. Then i started to think the way to implement this idea to our normal vehicle or so.

    Then i started to think about combining both system into 1 which can be called as Dual Braking system. Maybe this type is costly for present project. But as i understand normal braking system is completely relying on the fluid of the tube. while the magnetic force anyway is just electric generated eddy current to stop or slow down the speed as roller coaster did.

    So this is my idea for MY project.

    1st of all, combining both brake system into one. modify the current design on the disc brake and try to implement the magnetic device into the brake there.

    These is wat i have think about. just in case the normal brake failed, theres a back up magnetic braking system to slow down ur vehicle. OR the both brake act together so that the motion of the vehicle will get slower by percentage compared to only normal brakes.

    Guys. Give me ur thaught. I quite confidence on this project. And BTW, do we have any software simulation tat i can use to test about this case?

    Your help is much appreciated~!!!! Hope to see more idea's to help me out with this project. Previous comments is much grateful~!!! Thanks guys😛😛

    Ok, so you want elctromagnetic brakes then, they are the combination. I'd use them as the main brakes, replacing hydraulic completely as you already have a back up in mechanical e-brakes.

    Yup. Electromagnetic Brakes. I wan to combine it with hydraulic brake connecting it wih a electronics circuit board to control and determine when to use the electromagnetic brakes. so called (Double Acting Brake System)

    Hydraulic brake will act as a main type of brake. Just in case it is failed, then the circuit board detected failure and replacing the brakes to electromagnetic brake to stop the car. its similar to ABS if i not mistaken. But ABS is stop the 4 tire completely. But the idea is not to stop the tire, its to slow down the force and speed against the car, so that this could reduce accident rates.

    Ok, so you want two brake systems. ABS is actually different, it only prevents wheel lock (and loss of control due to lock)by modulating the brake force once lock is detected by sensors.

    yes, i think it would work.magnetic brake is one great idea that helps to decreese the rate of accidents due to brake failures and faults. you have to implement two strong electro magnets which magnetises when the brake pedal is pressed ,by taking charge from battery. this magnetised discs attract the wheel disc and retards its velocity of rotation, and with in fraction of seconds the vehicle will stop. its my idea regarding this. thank you.

    My paper is about electronic wedge braking system. It is similar to a conventional braking system but differs in the concept that it has no fluid inside as it is not a hydraulic type.
    This brakes has 2 pads like the conventional ones. After that it has a wedge shaped wooden block, followed by rollers to reduce friction, another wedge block and 2 motors controlling the wedge system. The diagrammatic illustration is given in the following URL.

    One very basic approach to make car breaks effective is tying a big parachute at the back of the car. As soon as break fails, there should be one EMMERGENCY button right in front of every seat.

    So that who so ever present in the vehicle notices some terrible about to happen, he simlply pushes that button and that big parachute will get inflated for instance and later its size will stop the car's motion.

    Unless it doesnt have ABS and resulting in wheel lock up... so without ABS it will be useless or say it will not get that advantage. think about the friction tooo

    I enjoy this much. My drawings for existing disc brake design is done. Now lets give it a try to modify on the caliper, to include coil and additional brake in to it.

    But i quite confuse. if this project is pure mechanical or mechatronic? Some of my frens says it is not pure mechanical project, as i explained to them that this design is to reduce speed more efficiently. By means the principal of reduction speed is base on mechanical formula. Force (f=d/dt) and

    friction

My supervisor agree with my idea, but he says i need a pure mechanical idea on my project and my current idea is seems doubted. But if i were an Electrical and Electronics Engineering, i allow to have a GO AHEAD on my current idea.

    Guys. What i should do now? Any idea suggestion? i need some advice. but i wont give up this idea easily before i meet my Dean to clarify this matter. Maybe electromagnetic is E&E, but come with the car case, its completely depends on mechanical functions.

    Guys. Please give me some suggestions. ~!!!! Thankz~!!!

    I think brake failure triggers a driver's reaction sequence..like TIGHT HANDLING OF STEERING WHEEL, IMMEDIATE HUGE PRESSURE ON BREAK PADS, VERY SWIFT STEERING movements.

    If a system could trap these reactions through motion sensors and repetetive testing to perfection.

    so that this system could drigger ENGINE closure, Some kind of Wheel jamming procedure will help curing the issue.

    hie i think the main problem with the pressure brake is that there should not be any leakage in pressure bt if we use better pressure system then there is no need for that magnetic brakes coz these pressure brkes have many advantages too.......the thing is that there should not be an air bubble in between that..............

    Idea pops out on the Drum Brake. Since we know that Drum Brake is more efficient than Disc Brake. In 80's Drum brake is invented and applied on the car. But Drum brake is too effective until when stoping the car, it stop the wheel turning instead the car it self.

    What i mean is the force which drum brake tries to reduce by expand the brake pad to touch the surface wall of the inner wheel. It locked the wheel from spinning, at it cause the car unbalance.

    So now i have an idea to modified the drum brake into Cone brake. I read a Mechanical Design book today and found out that this cone brake is useful to reduce the force generate by the torque of the engine. And it is more effective than Drum but it wont lock the wheel totaly.

    Hope u guys understand wat i trying to express. Any doubts just mail me or pm me here.

    Hope u guys have any suggestion on the idea's just please post it here. Share with me. Thx

    Erm... actually i not agree on it too. But my Lecturer said that the drum brake is better than disc brake. Initially when i propose my idea to him, i explain that drum brake is less contact (in the view of coefficient of friction against the inner wall of the wheel) then he said that YOU are wrong. And start telling that Drum brake is more effective than Disc brake.

    But what i suggest that the drum brake i could change the design with the flang with cone shape and compress the brake pad onto the surface of the cone. Erm. Can CEan's understand what i trying to say. Sorry I'm a chinese. So hard to explain in good english.

    I think you might be confusing drum brakes with disc brakes. Disc brakes started appearing heavily on cars in the 80's (although they had been around much longer than that) and are much more prone to wheel lock them drum brakes because they are more effective & do not experience fade as much. Drum brakes have been around for almost the entire history of mass produced automobiles.

    pad material compounds can play a huge roll, resourcing new compounds could be good. Same goes for rotors, better material and design for increased wear and heat/dust disipation could be good areas that will improve braking characteristics

Erm wat i mean is slightly changes on the discs shape and design on more friction contact surface and stuff like that.

    Increasing surface area wont help. Becoz friction is not depended on surface area.It only depends on the weight and force and inclination of the surface.

    It is true. Increase Surface area for friction is much likely better than the existing 1. the existing area surface is limited. so i think is better to increase the surface area. and

    Krishthd your true too. Changing the design of the disc is to help the cause of friction into heat could release even faster.
    Change of the shape on the disc could help the heat release. Ya its true. Both way can be done.

    Its been a while i left this post death~!! I'm back and wanted to post some of the pictures in here. i Guess i will receive many many critics about my works. BUT i need that to improve more on my project. I hope you all could help me.

    This below would be my current design.

    THis design is just a rough. so anything plz comment in here. AS i need CEan's comment to improve better than this.. THx...

    Just. I come out with an idea on Car Braking System. I see alot of accident due to the failure of the brakes either front or back brake. So i suggest that the braking system need to be improve. But i not sure where i can start to analyst which part i need to improve.
    Well. My final Year Project in On the way now. I wanted to stick with this idea.

    I thinking of the brake system - fluid compression to the clamp to stop the disk or drum to decelerate the speed of the car, Change to the clamp into a magnetic field. Its it an good idea? Coz the flow of fluid may cause the tube adding some air accidentally and sometimes the tube occur leakage.

    But if it does change to magnetic field to decelerate the disk or drum, i guess is more better than that rite? what u all guess suggest.

    BTW do this Magnectic Braking system available now?
    My view is if we use magnetic + conventional mechanism this may get success...

    can your design beat ABS - antilock braking system ? 😒

    it is possible if were to implement ABS to my design as well...

    Currently i were to test on the friction efficiency between existing and my design type...
    Hopefully it could be higher than existing brakes.

    Hello maxz,
    I have done final year project & seminar on same subject.

    first thing the fluid used for such braking system is called as Magneto Rheological fluid or MR fluid. It is one of the smart materials. Its property is; when it is subjected to magnetic field its viscosity increases. Magnetic field converts it into semisolid state from liquid. Its very costly, 25000/lit and its manufactured only in USA.

    So think about this project twice; as its setup & MR fluid is very costly.

    This braking system comprises of, a tough steel plate, surrounded with a drum. this drum contains MR fluid & electrical windings are provided over drum so as to create magnetic effect. Steel plate is attached with the shaft which drives the wheel.

    So when there is need to apply brake just increase magnetic effect, which will increse viscosity of MR fluid which will oppose to the rotation of shaft & brake will be applied.

    This kind of system is not used in current vehicles as at higher rpm MR fluid leaks out of drum. & at higher speeds MR fluid can not be semi solid as quick as at slower rpm's.

    Prof. H. Hirani IIT Powai (Mumbai) is working on it.

    Automobile giants like GM are working are seeking to develop a magnetorheological fluid based clutch system for push-button four wheel drive systems. This clutch system would use electromagnets to solidify the fluid which would lock the driveshaft into the drivetrain.

    I see.... but i think there's some alternative way to use on the improvement.. since i graduated, i never look on the research already. Moreover, there is no sponsor for me to continue the studies.

    HEllo Maxz,

    I done this project with the sponsorship of my college, but it was not successful.
    As funds were insufficient; & project was too much costly.
    Sponsors are always req for such project, but not had that much reach at that time (Before 3 Years).

    I dont know about recent advances in MR break (Magneto Rheological break) but, some
    solution must be raised to solve the problem of fluid leakage & change in state of MR fluid at higher rpm's.

    Actually I was not on CE when you raised this thread, at that time I could have helped you. hmmm

    Let it be. so you have completed your project; please tell me details.!!!

    well~ for my project, i just studies on the design of the braking plate and the material of it only. as i mentioned, no sponsors. so i have to reduce the size of scope that actually need to cover for my entire project. I have my file for my new design of 1 phase braking surface that i already did some testing, and its slightly better braking power than dual surface braking. Hmmm

    hey people ...i am thinking of a project to make for my final year ,,,,,i m thinking of a tilting headlamps sideways ,that is left to right
    ,,it will move according to the steering movement ,,,,,purpose is that ,,during a sharp turn ,,the light beam usually goes straight ,and doesn't turn with the car,,,,so i wan to move headlamps sideways....

    please help me ,,is this possible,what all things a\can i use,,
    can i use a hydraulic unit,or a electronic unit
