dynamic bracket

grabcad

This bracket features a spring action that permits temporary bending and twisting, thus alleviating peak loads. Titanium, an ideal spring material, is used in its design. However, static simulations do not accurately depict part performance. The strength of this bracket lies in its ability to quickly react and redistribute load across a wider area. Additionally, the spring sections spiral wind for kinematic space displacement, primarily canceling out. For contest purposes, it is provided as a single solid; however, the actual product consists of two or more loose pieces that pivot around bolt axis when stress demands. Prior to installation, pieces appear bowed, and assembly does not lie flat until bolted down, intentionally preloading springs. Tensioned structures maintain stiffness without sacrificing elasticity. Alternatively, the bracket can be formed using die forged sheet titanium pieces joined by laser welding. Metal forging results in superior tensile strength as grain directions align with part shape. Manufacturing is faster, cheaper, and offers better performance. Total volume reduction from benchmark bracket is 90.2%.
