Abstract:
Bow-springs find few applications in industry. Principally, they are used in archery. In addition, they have found some use in a compression-spring mode in the field of biomechatronics, to emulate elastic human legs. The mechanical behavior (characterized by deflected shape and deformation force) is difficult to model, because internal forces and moments and the geometry are both unknown. The only closed-form solutions to such systems are relatively useless to a mechanical engineer. This work comprises an iterative model developed in MATLAB that computes the mechanical behavior of buckled beam (or bow-spring) sections, over a range of parameters and geometries, to be used in the development and testing of compression bow-springs as parallel loading systems to the human leg.
Description: Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, February 2011."May
So this is unknown territory. What can we build on to get energy out in the world that can power a cooking stove for a day?
My fork in the road is four way. 1. Stick to
Conventional spring technology. 2. Track nanotubes (slow in development). 3. Review the flywheel application. 4. Look at this emerging interest in composite bow-spring application.
The decision will make or break the stove for millions of people. I want something NOW to hit the market with. Help me sort this out.
