基于正交试验设计的电磁继电器关键调整参数及优化方法
Key Adjusted Parameters and Optimum Method of Electromagnetic Relay Based on Orthogonal Experimental Design
摘要
Abstract
On the stage of electromagnetic relay's being adjusted, the technical control of adjusted parameters directly affects relays' characteristics of reaction force, and changes the match of attractive force and reaction force. It eventually influences the breaking velocity of relay's contacts. And the change of contacts' breaking velocity has a great effect on relays' electrical lifespan. Taking adjusted parameters (including armature's maximum angular displacement, initial return spring's force, normally closed contacts' force, contacts' gap and normally open contacts' over travel) as factors and breaking velocities as targets, this paper does the orthogonal experimental design of five factors and four levels, analyzes and investigates the key adjusted parameters influencing breaking velocities. The research results indicate that α_(arm_max),δ_(gap) and δ_(NO_(_contacts)) are the key factors affecting breaking velocity of NC contacts, δ_(NO_(_contacts)) is the key factor affecting breaking velocity of NO contacts. Then, based on the above work, optimum method of adjusted parameters is presented.关键词
