Method for testing electromagnetic field emission intensity of electric vehicle based on vehicle body three-dimensional model

Abstract

The invention relates to a method for testing the electromagnetic field emission intensity of an electric vehicle based on a vehicle body three-dimensional model. The method comprises the steps of building a complete vehicle three-dimensional model of the electric vehicle and an electric wave darkroom model; when the electric vehicle operates under a test condition, testing the electromagnetic emission intensity of high-voltage driving system components to obtain radiation source data, and loading the radiation source data to a corresponding component model and wiring harness model of the electric vehicle; importing the complete vehicle three-dimensional model to which the radiation source data is loaded into the electric wave darkroom model, and performing simulation calculation and conversion on the electromagnetic field emission intensity of the electric vehicle to obtain a final simulation result. When the test result cannot meet requirements, rectification is performed on the high-voltage driving system components and wiring harnesses thereof, and the radiation source data measured after the rectification is measured again and loaded to the corresponding component and wiring harness model, so that measurement is not required to be performed on the complete electric vehicle repeatedly by using the electric wave darkroom, the economic cost of the electromagnetic compatibility test performed on the electric vehicle is reduced, and the test period is shortened.

Description

technical field [0001] The invention relates to the technical field of electromagnetic compatibility simulation of electric vehicles, in particular to a method for testing electromagnetic field emission intensity of electric vehicles based on a three-dimensional model of a vehicle body. Background technique [0002] At present, the energy of traditional fuel vehicles mainly depends on oil, and the shortage of oil and the serious pollution of the environment caused by the tail gas of fuel emissions have made it more and more urgent for human beings to research new green vehicles. As a green transportation tool, electric vehicles not only have remarkable energy-saving effects, but also greatly improve the comprehensive utilization rate of energy, and have zero exhaust emissions and obvious environmental benefits. Therefore, electric vehicles are more and more widely used. [0003] The high-voltage electric drive system parts of electric vehicles, such as batteries, motor contr...
