高处跌落幸存者的受力分析

Mechanical Analysis of Survivals in High Crashes

通过建立力学模型,详细阐述了飞机从高空坠落时,舱内乘客在落地时的受力情况。通过Laplace变换及其反变换,计算出了普遍情况时乘客的受力,并求出了在特殊时刻,乘客所受到的力正好为零,从而提出了高空乘客在出现紧急情况时的应急措施。

By establishing the mechanical model, the author analyzes the mechanical situation of the passengers in the plane while it crashes. By substituting of the Laplace and counter-substituting the Laplace, the author calculates the mechanic suffering of the passenger at the general time, and concludes the solution that the mechanic suffering equals to zero at the special time. Finally, the author puts forward some emergency measurements in the condition part.
