摘　　要：为分析棉纺精梳机钳板摆轴驱动力矩的变化规律,探讨了锡林梳理力、分离牵伸力、钳板机构惯性力、钳板摆轴惯性力及其与钳板摆轴驱动力矩关系。建立了钳板摆轴阻力矩及驱动力矩的数学模型,运用ADAMS软件对一个工作周期内钳板摆轴的阻力矩及驱动力矩的变化规律进行仿真模拟。结果表明:钳板摆轴的驱动力矩主要取决于钳板机构的惯性力对钳板摆轴的矩;随着精梳机的速度提高,钳板摆轴驱动力矩变化曲线的峰值及谷值迅速增大,钳板机构的惯性力对钳板摆轴驱动力矩影响增大;当精梳机的速度由300提高至500钳次/min时,驱动力矩曲线的峰值增大211%,钳板机构惯性力矩峰值与钳板摆轴驱动力矩峰值比值由63%增至74.1%。In order to understand driving torque of the nipper pendulum shaft of the cotton spinning comber,the carding force,separate drafting force,inertia force of the nipper mechanism,inertia force of the nipper pendulum shaft were analyzed and their relationships with the driving torque of the nipper pendulum shaft was investigated.Mathematical models for the drag torque and the driving torque in the nipper pendulum shaft were established,and the ADAMS software was used to simulate the variation mechanisms of the drag torque and driving torque of the nipper pendulum shaft during a working cycle.The results show that the driving torque of the nipper pendulum is mainly determined by the torque of inertial force in the nipper mechanism for the nipper pendulum shaft.The peak and valley values of the driving torque curve of the nipper pendulum shaft are increased rapidly with the increase of comber speed,and the influence of the inertial force in the nipper mechanism on the driving torque of the nipper pendulum shaft becomes more significant.When the speed of the comber is increased from 300 to 500 nippers/min,the peak value of the driving torque curve is increased by 211%,and the ratio of the peak inertia torque of the nipper mechanism to the peak driving torque of the nipper pendulum shaft is increased from 63%to 74.1%.
