摘要
为实现压力容器的零泄漏动密封传动,提出一种磁力耦合驱动结构的优化设计方法。以耗费永磁材料最少的情况下实现传递转矩最大、涡流损耗最小为优化目标,构建改进粒子群算法,对磁力耦合驱动结构进行参数优化设计。根据优化结果设计磁力耦合驱动结构,并通过三维有限元仿真及试验检测验证了所设计结构可满足实际应用的转矩要求,实现了压力容器的零泄漏动密封,可为同领域磁力驱动结构的设计提供指导。
In order to achieve dynamic sealing in pressurized vessel considering non-leakage of harmful working medium,this study presents an optimal structure design of permanent magnetic coupling(PMC).For the optimization objective of increasing the torque transmission with limited magnetic material cost and decreasing the eddy-current loss of the magnetic coupling caused by the metal isolation cover,an improved partial swarm optimization method is designed to perform a multiobjective design optimization of the structure of PMC.After accurate computation,the optimal structure parameters of PMC are obtained.Then,a 3-D finite element model of PMC with the optimal structure is constructed to analyze the transmitted torque and eddy current loss,and an actual PMC device is manufactured for the non-leakage vessel application and the tested performance satisfies the technical demands,which provides theoretical reference for the PMC structural design in similar applications.
