Development of an impact-decreased bonnet of an automobile protecting a walker

本研究利用薄壁弹性体之挠度与平面位移间之非线性耦合，开发出一种可降低步行者在交通意外时所受冲击力之汽车引擎盖。为了减小冲击机构的设计，分析了连续弹性体在冲击作用下的非线性响应。因此，曲率和弹性约束的影响的冲击力进行了详细的调查。

In this research, utilization of nonlinear coupling between deflection and in-plain displacement in a thin-walled elastic body to develop an automobile bonnet with can minimize impact force for a walker in a traffic accident. For the design of an impact-decrease mechanism, nonlinear responses of a continuous elastic body subjected to an impact are analyzed. As a result, effects of a curvature and elastic constraint on the impact force are investigated in detail.
