Modeling of electromechanical actuators using multi-body dynamics

This paper proposes a modeling method of electromechanical actuator (EMA) system including nonlinear links and multi-body dynamics problems with flexible bodies. Since the two nonlinear characteristics can affect the dynamic characteristics of the system, the analysis of their effects on the system can be carried out closer to the actual situation. According to various situations, the mathematical model of the system is studied. Then the simulation model is established in Matlab software to verify the influence of nonlinear factors on dynamic characteristics of the system.
