本文建立了转炉全悬挂倾动系统的三个动力学数学模型。倾动系统被区分为交流电机拖动系统或直流电机拖动系统。驱动力矩不再象以往那样简化为阶跃函数,而是决定于所用电机的实际机械特性。弹性尖峰力矩对于扭力杆缓冲装置的扭转刚度K_1的实验曲线与理论曲线基本一致。实验和数值分析都表明弹性缓冲装置能够显著地降低尖峰力矩。通过约束优化的数值方法解决了扭力杆缓冲装置的参数设计。
In this paper, three dynamic mathematical models of converter full suspension tilting system are established. The tilting system is divided into AC motor drive system or DC motor drive system. The drive torque is no longer reduced to a step function as before, but rather depends on the actual mechanical properties of the motor used. The experimental curve of torsional stiffness K_1 of elastic peak torque to the torsion bar buffer device is basically the same as the theoretical curve. Both experimental and numerical analyzes show that the elastic damping device can significantly reduce spike torque. The parameter design of the torsion bar buffer device is solved by constrained optimization numerical method.
