摘　　要：实际工程中有许多同时含有粘滞阻尼和干摩擦阻尼的振动系统需要对其进行振动控制,以减少因此带来的结构损伤。依据频响仿真,结果表明经过一个暂态过程后,主振动系统振动为零。运用此方法对某化工厂苯加氢管道振动进行了治理,使其加速度响应降到了原来的1/10,达到了较好的振动控制效果。In practice, there is a sort of vibration systems need decreasing its vibration which contains both the coulomb and viscous damping. Based on the response equation, the simulation shows the vibration of the system trends zero. Acceding by the equation, the acceleration response is reduced to 10 times in the pipeline system of a chemical plant.
