摘要
Abstract
The electromagnetic radiation simulation of pure electric vehicles has the problems of many in-terference sources,complex model structures,deep integration of electromagnetic fields,large amount of calculation and long simulation time.Based on the basic theory of electromagnetic radiation,an effi-cient electromagnetic radiation simulation method for establishing equivalent model was proposed,which was used to analyze the electromagnetic radiation inside certain pure electric vehicle and the real vehicle test was verified.The results illustrate that the simulation method is reliable when the electromagnetic radiation simulation of pure electric vehicle is conducted,and the error between electromagnetic radiation simulation inside vehicle and test results is less than 8%.Meanwhile,it can achieve the purposes of re-ducing calculation amount and lowering simulation time.Taking drive motor as research obj ect,the sim-ulation time of this method is reduced by about 78% compared with the general method.The method can provide a reference method for the electromagnetic radiation simulation under combined action of multi-ple electrical devices.关键词
