摘　　要：经编机在高速运行时会有较大振动与噪音,为优化梳栉横移的平稳性和精确性,对梳栉机构进行简化分析、建立动力学模型,根据动力学微分方程求解系统对零初始条件的响应。根据实际工况,提出高速经编机梳栉部分的减振措施,并用Ansys workbench仿真分析,求解梳栉部分固有频率,并对伺服电机的不同驱动力输入方式进行比对,选择合适驱动力输入规律作为伺服电机输入。The warp knitting machine will have large vibration and noise when running at high speed. In order to optimize the stability and accuracy of the transverse movement of the comb, a simplified analysis of the comb mechanism was carried out, a dynamic model was established, and the response of the system to zero initial condition was solved according to the dynamic differential equation. Accord-ing to the actual working conditions, the vibration reduction measures for the comb part of high speed warp knitting machine were put forward, and the natural frequency of the comb part was solved by using Ansys workbench simulation analysis, and different driving force input modes of servo motor were compared, and the appropriate driving force input rule was selected as the servo motor input.
