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

在本研究中，利用薄壁弹性体挠度与平面位移之间的非线性耦合，开发了一种能使行走者在交通事故中受到的冲击力最小的汽车引擎盖。为设计减震机构，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冲击力的影响。

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.
