干摩擦对临界阻尼状态缓冲特性的影响

Effect of dry friction and critical domping on Cushioning character

根据单自由度、临界阻尼状态的动力学模型．考虑了干摩擦的存在对缓冲特性的影响，导出了包装件受冲击作用时产品的最大冲击加速度和缓冲材料的最大形变的表达式．并与无阻尼系统的相应情况进行了比较。

In the paper,dry friction and critical damping on cushioning characteritic effect is studied,the largest impact acceleration 0f the enclosur and the largct deforming of the cushioning materialare derived when encourtering impact.
