纯电动汽车性能仿真与驱动电机选型分析

Performance Simulation of Electric Vehicle and Analysis of Drive Motor Selection

在整车开发策划前期,纯电动汽车的动力性能指标,是通过研究竞品标杆车型水平,以及符合政策法规要求等的前提下,去初步制定出来具有前瞻性竞争力的动力参数指标。为了实现参数定义的动力指标,需要选择合适的驱动电机及传动比以达到此设计目标。通过搭建动力仿真模型,结合实际驱动电机性能,仿真分析比对不同产品在整车上搭载后的能力,进行对比,最终作为驱动电机选型的主要理论依据。

In the early stage of vehicle development and planning,the dynamic performance indicators of pure electric vehicles are based on the premise of researching the level of competing models and meeting the requirements of policies and regulations to initially formulate forward-looking competitive power parameter indicators.In order to achieve the power index defined by the parameters,it is necessary to select a suitable drive motor and transmission ratio to achieve this design goal.By building a dynamic simulation model and combining the performance of the actual drive motor,the simulation analysis compares the capabilities of different products after they are mounted on the vehicle,and makes a comparison,which ultimately serves as the main theoretical basis for the selection of the drive motor.
