摘　　要：研究了单自由度滑动摩擦系数随相对速度变化的干摩擦振动系统随机激励响应计算问题 ,提出了Krylov- Bogoliubov近似方法 ,并推导了相应的均方响应迭代方程。通过一个数值例分析 。By using Krylov-Bogoliubov approx imate technique, the response computation of a single-degree-of-freedom dry friction damped system with velocity-dependent variable coefficient of sliding friction under random excitation was discussed, and the mean square response equ ation was also derived. At the same time, the error between Coulomb friction sy stem with a system with velocity-dependent variable coefficient of sliding fri ction was obtained.
