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.

在本研究中，利用薄壁弹性体中挠度与平面内位移之间的非线性耦合，开发出一种能使行人在交通事故中受到的冲击力最小的汽车引擎盖。为了设计减震机构，分析了连续弹性体在冲击作用下的非线性响应。因此，详细研究了曲率和弹性约束对撞击力的影响。
