摘　　要：基于动力学理论,建立了采煤机截割部双电机机械串接系统的动力学模型,分析了截割部工作机构在交变载荷、阶跃载荷和冲击载荷作用下,系统刚度、双电动机间连接刚度和双电机的机械特性差异对电机同步性的影响,证实了连接刚度的增大对双电动机的同步运行有显著的影响,系统刚度和双电机的机械特性差异对同步性影响不大。Based on dynamic equations theory,established dynamic model of two-joint-motor machinery series system,analyzed when cutting unit under alternating load,step load and impact load,affected of system stiffness,the connectional stiffness between dual-motor and differences mechanical properties of motor to the motor synchronous,confirmed that increase connectional stiffness has a significant impact,little effect by system stiffness and differences mechanical properties of motor.
