在非线性干摩擦系统动力学模型的基础上，结合金属摩擦片的强几何非线性力学特性，利用分段杜哈梅积分的方法推导了干摩擦隔振器在较大冲击载荷下的加速度响应计算公式，将理论计算结果与摆锤模拟大冲击的试验结果作对比发现，该方法能够较好地反映金属干摩擦隔振器在较大冲击下的运动规律。
Abstract
Based on the dynamic model of a nonlinear dry friction system,combining with the strong geometric nonlinear mechanical charactristics of mental friction plates, the calculation formula for acceleration response of a dry friction isolator under larger impact load was derived by using the piecewise Duhame integral method.The theoretical calculation results were compared with test ones of pendulum to simulate large impact.It was shown that the proposed method can better reflect motion laws of a metal dry friction isolator under larger impact.
