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 dualdrive elastic turntable’s middle frame deformation analysis, and the conclusions are helpful for the further research on the deformation feedback control.
