摘要: 提出了一种考虑运动学和振动解的摩擦振动模型,并用迭代法求解了压电执行器在运动体摩擦力作用下的振动响应.通过数值模拟和参数分析研究了运动体的速度v,正压力FN,相对滑动速度控制系数的延迟率C,静摩擦系数μS及其下限μD,阻尼比ξ对于动态摩擦力和振动特性的影响趋势.结果表明压电堆的振幅随着FN,v,μS和C的增加而变大,随着μD和ξ的增加而减小.FN和μS影响最大静摩擦力,μD影响滑动摩擦力,v和C对黏着状态与滑动状态的转换以及摩擦状态转换过程中摩擦力的变化有明显的影响.

Abstract: A friction vibration model considering kinematics and vibration solution was proposed, and the vibration response of a piezoelectric actuator under friction force from a moving object was solved by the iterative method. The influences of the moving object velocity v, normal pressure FN, delay rate of relative sliding velocity control coefficient C, static friction coefficient μS and its lower limit μD,damping ratio ξ on the dynamic friction force and vibration characteristics were studied by numerical simulation and parameter analysis. The results showed that the amplitude of the piezo electric stack increases with the rise of FN, v, μS and C, and decreases with the increase of μD and ξ.FN and μS affect the maximum static friction, μD affects the sliding friction, v and C obviously affect the transformation between the sticking and sliding friction status and the friction force variation during the conversion of friction status.
