A three-phase AC motor-elastic linkage mechanism system with links fabricated from three-dimensional braided composite materials is taken as the object of study.According to the transverse vibration and torsional vibration of motor shaft and the 3-dimentional microstructure characters of three-dimensional braided composite materials,a group of coupling dynamic nonlinear equations of the system,which include composite materials parameters,electromagnetism parameters of motor and structure parameters of elastic linkage mechanism,are established by the finite element method.The non-linear characteristics of self-excited inertial forces are analyzed.The inner relations between the dynamic responses of the system and the microstructure parameters of composite materials,electromagnetism parameters of the drive-motor,the structure parameters of the mechanism and the transverse vibration are studied.Through analysis of an example,some valuable conclusions are obtained and verified.
