The selection and matching of electric vehicle power system is a key issue in the development process of the whole vehicle. According to the vehicle parameters and performance indicators, the key parameters of the motor and the power battery pack are determined by matching and calculating the power system. Based on the cruise simulation software, build the electric vehicle simulation analysis model, and take the power and economic simulation analysis. According to the comparison between the simulation results and the experimental data, the rationality of the simulation model is further determined, which lays a foundation for the subsequent simulation optimization.
The response characteristics of the high-pressure common rail injector affect the fuel injection characteristics of the diesel engine, which in turn affects the engine's power and emission performance. This paper takes the high pressure common rail injector as the research object, uses the AMESIM to simulate and analyze the high-pressure common rail injector. Optimization Design the four key structural parameters and selected the optimization plan. By comparing the results of the injection law curve and the cycle injection quantity, it determined that the optimization plan is close to the actual demand value of the project, which proves the rationality of the optimization plan.
