摘要:
为了实现摆动气缸的伺服精确定位,研究开发了一种内置磁流变阻尼器的伺服摆动气缸。提出了磁流变阻尼器的结构与磁路的集成优化设计模型。推导了磁流变阻尼器的阻尼力矩公式。以最大阻尼力矩和最小磁流变阻尼器体积为单目标函数,利用线性加权和法建立综合目标函数。采用遗传算法获得满足饱和磁感应强度和阻尼器核心结构参数要求的最优方案,使阻尼器的阻尼性能提高了64.4%。经电磁有限元分析验证该优化方案是可行的。
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.
