Current Status and Development Trend of Experimental Verification Technology of Traction Drive System

Traction drive system experimental verification technology after many years of development, gradually from the physical test bench mainly simulation experiments supplemented by experimental verification means for the development of physical test bench, computer simulation, semi-physical simulation and other means of experimental verification means, the future in the physical test bench, hardware in the loop simulation, etc., on the basis of the development of digital twins, based on the information-physical technology, digital and physical fusion of the integration of digital virtual test Simulation technology, through higher simulation accuracy and simulation coverage, to reduce the number of physical test tests of traction components and systems, reduce the cost of testing and certification of traction power systems on board, is an important development trend of the experimental verification technology of traction drive systems.
