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简谐激励响应计算问题 ,提出了等效线性化处理方法 ,并推导了相应的频响方程。通过一个数值例分析 。
In the paper,by using equivalent linearization technique,the response computation of a single_degree_of_freedom dry friction damped system with velocity_dependent variable coefficient of sliding friction under harmonic excitation is discussed. The amplitude_frequency equation is also derived.The error comparison between system with coulomb friction and with velocity_dependent variable coefficient of sliding friction is put forward.
