摘要


利用分段线性方法对含库仑阻尼系统的冲击方程进行了解析求解。研究发现,忽略库仑阻尼的粘滞作用,或对冲击激励进行速度阶跃等效,会造成冲击响应计算结果严重偏离正常值。利用仿真结果给出了库仑阻尼系统冲击响应的特点,得出库仑阻尼的加入可有效地提高冲击隔离器的抗冲性能。研究结果对于深入研究库仑阻尼系统冲击响应有重要参考价值和潜在的应用价值。



Abstract

Using piecewise linear method, analytical function solution for shock isolation system with coulomb damping is obtained. Further analysis reveals that carrying through velocity step equivalent or taking no account of adhesion effect will leads wrong results. Through simulation shock response characteristics of coulomb damping system are given, which suggest that coulomb damping is helpful in shock isolation if it is properly used. The research develops the theory of coulomb damping shock response.
