摘要：

对操作机夹钳旋转简谐振动原理进行分析，总结出径锻机锤头位移和操作机夹钳间歇性旋转动作之间的对应关系，并利用Amesim搭建了径锻机夹钳简谐振动系统的仿真模型，建立了锤头位移与简谐振动液压伺服阀信号之间的函数关系，将锤头位移转化为液压伺服阀控制信号为折线、等加减速曲线、正弦曲线3种函数关系。在其余参数相同的条件下改变锻造频次，对以上3种函数关系实现的简谐振动效果进行对比分析。结果表明：在低频次锻造时，液压伺服阀控制信号为等加减速曲线的控制效果更理想；随着锻造频次的增加，夹钳瞬间停顿时间较短，而正弦曲线控制效果更理想；同时，高频次锻造时，夹钳旋转动作明显滞后于控制信号，需精确调节锤头位移传感器与偏心轴的相对角度或传感器的相对零点。

The simple harmonic vibration principle of the clamp rotation for manipulator was analyzed, and the corresponding relationship between the hammer displacement of radial forging machine and the intermittent rotation action of manipulator was summarized.A simulation model of the simple harmonic vibration system for radial forging machine was built by Amesim. Then, the functional relationship between the hammer displacement and the signal of simple harmonic vibration hydraulic control valve was established. Finally, the hammer displacement was converted into the control signal of hydraulic valve as three functional relationships: broken line, equal acceleration and deceleration curve and sine curve. The forging frequency was changed under the same conditions of other parameters, and the simple harmonic vibration effects achieved by the mentioned three functions were compared and analyzed. The results show that when forging at low frequency, the control effect is more satisfactory by using the equal acceleration and deceleration function curve signal to control hydraulic valve. As the forging frequency increases, the instantaneous pause time of the clamp is shorter, and the control effect is more satisfactory by using the sine curve signal to control hydraulic valve. When forging at high frequency, the rotation action of the clamp obviously lagged the control signal, and the relative angle of the displacement sensor of hammer and eccentric shaft, or the relative zero point of the displacement sensor needs to be adjusted accurately.
