摘　　要：本文在分析浮码头撞击的线性振动基础上，针对广泛采用的防冲设备—橡胶护舷（非线性弹簧），提出非线性动力响应的分析方法．对复合体系（船－浮码头－撑敦）非线性动力方程应用样条加残配点法进行直接积分．考虑非线性阻尼，采用切线刚度及拉格朗日插值函数，给出撞击力及撑杆动内力的最大值，为工程应用提供有效方法．The analytical method for solving nonlinear dynamic response of rubber fenders,currently used as a damper to prevent from percussion of the ship,is presented in this paper.The nonlinear dynamic equation for the complex system(ship-pontoon pier-standing pier) is integrated directly by using S--WRM(C) method (spline--weighted residual method of collocation point). The percussion force and maximum dynamic stress of the supporting rod are to be calculated with nonlinear damping and tangent stiffiness and lagrange interpolating function are applied.
