摘要： 为了分析双马达驱动系统的输出力矩对考虑弹性的转台中框变形的影响，采用ANSYS有限元工具对转台中框进行了模态分析.利用ADAMS软件的柔性模块，基于模态的线性叠加方法，研究了双马达输出力矩在同步和不同步驱动情况下的转台中框变形响应，分析了转台框架变形的原因.仿真结果表明，合理地施加双马达输出角加速度以及保证双马达输出完全同步转矩可以有效抑制转台中框的变形.

Abstract: In order to analyze the deformation of the dual motor driving elastic turntable’s middle frame, a finite element model was established for modal analysis by ANSYS. Based on the method of modal superposition by ADAMS flexible module, the deformations of turntable’s middle frame driven by synchronous and asynchronous torques were studied, and the cause of deformation was analyzed. The maximum deformation position of the turntable’s middle frame was calculated. The results of simulation indicate that the driving turntable’s middle frame by synchronous torque and keeping its angular acceleration reasonable can effectively restrain the deformation. This paper provides an effective method of simulation for the dualdrive elastic turntable’s middle frame deformation analysis, and the conclusions are helpful for the further research on the deformation feedback control.
