Spring force characteristic is very important to relay＇ s design, assembly, debugging, reliable operate. Spring compliance is foundation of spring force characteristic calculation, so first of all, this paper works out spring compliance based on deformation energy method, then a universal calculation method that can calculate spring force characteristic of any shape spring system present in the paper. To prove the validity of the universal method, spring force characteristic of a certain electromagnetic relay is calculated by the method, and the real spring force characteristic is tested with a testing equipment. The comparison result indicates that universal method in spring force characteristic calculation of electromagnetic relay can meet the requirement of engineering application. Based on all of these, Visual C ＋＋ is adopted to development a software system in spring force characteristic calculation of electromagnetic relay. This software has characteristic of friendly interface, easily modeling and quickly calculating, and can do some help to relay＇ s design and research.
