Modelling and simulation of mechanical transmission in roller-screw electromechanical actuators

摘要

The research work presented in this paper aimed at providing a system-level model of the mechanical power transmission in an inverted roller-screw EMA. Despite all results were got for an industrial EMA prototype designed for on-ground testing of flight control actuators, all modelling and simulation results can be applied with profit to a flying EMA operating at a room temperature. However, the influence of operating temperature on model parameters is still to be assessed.
