摘　　要：建立了基于ADAMS的内置式动力减振镗杆动力学仿真模型,以减小刀刃径向跳动在整个频域内响应的最大值为目标对样机模型进行了优化分析,得出了减振系统的最优参数。仿真试验表明优化后系统的频域响应得到了改善。在此基础上分析了模型中的弹簧刚度系数、粘性阻尼系数、调谐块质量、减振腔尺寸以及调谐块质心位置对系统减振效果的影响,为减振系统进一步的优化设计提供了设计依据。The dynamical simulation model of the vibration absorption system is build up in ADAMS foftware. Aiming at minimizing the maximal value of magniuted-frequency response, the virtual prototype of vibration absorption boring bar has been optimized and the optimized parametes are obtained. The simulation results show that the system responses in the frequency domain have been better than before. Based on this model, the influences of the spring stiffness coefficient, the damping coefficient, the mass of heary turning body, the dimension of vibration absorption hole and the mass point of heavy turning body on the vibration absorption effect of the system are discussed. Further design considerations about optimization design of the vibration absorption system are given.
