Abstract: With the rapid development of electrification technology in the commercial vehicle sector, the electric drive axle system, as an efficient and energy-saving driving method, has gradually attracted attention. This article conducts configuration research, matching calculation and dynamic simulation analysis for semi-trailers equipped with electric drive axles. Firstly, the integration mode,layout position of the electric drive axle and its comparison with traditional fuel-powered semitrailers are discussed, and the influence of different configurations on vehicle performance is analyzed. Secondly, based on the parameters and performance requirements of conventional semitrailers, matching calculations and designs are carried out, and the dynamic model of the semi-trailer is established based on the Cruise software. Through simulation analysis, the influence of the configuration of the electric drive axle on the vehicle's acceleration performance, climbing performance and energy consumption is studied. The results show that the reasonable configuration of the electric drive axle can enhance the dynamic performance of the semi-trailer and reduce energy consumption at the same time. In addition, suggestions for optimizing the configuration are put forward, providing theoretical basis and technical support for the application of electric drive axles in semi-trailers. The research results are of great significance for promoting the electrification development of semi-trailers.
