Abstract:
For servo precise location of pneumatic rotary actuators,a novel servo pneumatic rotary actuator with a magnetorheological damper inside is designed.An integrated optimization design model for the structure and magnetism of the magnetorheological damper is proposed.A damping torque formula of the magnetorheological damper is derived.A comprehensive objective function is established by the linear weighting and summation method with the maximizing damping torque and minimizing damper size as single objective functions.An optimization scheme that can meet the saturation magnetic induction intension and core structure parameter requirements of the damper is obtained based on the genetic algorithm,and the damping properties of the damper is increased by 64.4%.The feasibility and credibility of the optimization scheme is validated by electromagnetic finite element analysis.
