摘要

针对气动针刺式巨量转机构在高速、高频刺晶过程横梁扭转振动影响转移精度问题，提出了一种基于动态平衡法的双边侧挂直线电机主动减振方案，基于同步反向运动的针刺系统和随动系统，建立了横梁扭转振动幅值的数学模型，并使用有限元法对运动过程进行瞬态分析。直线电机电流控制上采用了BP-PID (Back Propagation- Process Identifier)方法调控参数，提高了电流函数收敛速度，降低了启动电流超调量，优化了电机推力的控制方法。试验表明，在不间断加速模式与高速启停模式下分别减小横梁振幅86.74%与84.47%，证明了动态平衡法主动减振结构对抑制气动针刺巨量转移装置横梁扭转振动效果明显，对巨量转移精度提升具有重要意义。

Abstract

In response to the issue of the impact of beam torsional vibration on the transfer accuracy during the high-speed, high-frequency piercing process of the pneumatic needle piercing mass transfer mechanism, a bilateral side-hung linear motor active vibration reduction scheme based on dynamic equilibrium method was proposed. Based on the synchronous reverse motion of the piercing system and the follow-up system, a mathematical model of the torsional vibration amplitude of the beam was established, and the transient analysis of the motion process was conducted using the finite element method. In the current control of the linear motor, the BP-PID (Back Propagation-Process Identifier) method was used to adjust the parameters, which improved the convergence speed of the current function and reduced the overshoot of the starting current, optimizing the control method of the motor thrust. Experiments have shown that the amplitude of the beam was reduced by 86.74% in the uninterrupted acceleration mode and by 84.47% in the high-speed start-stop mode, proving that the dynamic equilibrium method active vibration reduction structure has a significant effect on suppressing the torsional vibration of the beam in the pneumatic needle piercing mass transfer device, which is of great importance for improving the mass transfer accuracy.
