doi:10.3901/JME.2022.17.058

Abstract

Abstract: The permanent magnet retaining unit provides sufficient holding force for the repulsive operating mechanism at the opening and closing position. It is an important component to maintain the opening or closing state of the mechanical switch. Its structural parameters and output characteristics are the key factors for the reliable opening and closing of the switch. Aiming at the problems of uncertain machining tolerance, poor assembly consistency, interrelated output dynamic characteristics of sensitive parts of retaining unit of repulsive operating mechanism, the interval uncertainty model is introduced into the analysis of output characteristics of retaining unit system, and a multivariable and multi-objective optimization method based on non-dominated sorting particle swarm optimization is proposed. Firstly, based on the three-dimensional finite element model of the retaining unit, the influence law of the tolerance uncertainty of the moving iron core and magnetic guide ring on the output force of the holding element is obtained. Based on the tolerance influence analysis of the sensitive parts of the retaining unit, the mechanical parameters of the permanent magnet retaining unit are selected as the optimization variables, the cost and bounce of the operating mechanism are considered, the uncertainty of the tolerance of the magnetic guide ring and the moving iron core is considered, the multi-objective optimization design model of the retaining unit of the repulsive operating mechanism considering the uncertainty of the tolerance is established, and the set of non-dominated solutions of Pareto frontier is obtained. Finally, based on the optimized retaining unit structure, a fast vacuum switch experimental platform is built for the opening and closing experiment of the repulsive operating mechanism. The system can complete the opening and closing action within 15 ms. The research shows that the optimization method ensures that the retaining unit of the repulsive operating mechanism can play its role to the greatest extent under different manufacturing, and allows low grade tolerances for the parameters of the moving iron core and magnetic guide ring.
