整车操纵性能仿真客观评价体系研究

Study on Objective Evaluation System of Whole Vehicle Handling Performance Simulation

根据整车评价的实际工况确定科学的六分力试验方法,建立轮胎的PAC2002模型;根据整车悬架的运动学与动力学试验数据和转向系统试验数据,在Carsim软件中建立某品牌SUV整车模型;根据GB/T 6323—2014和主观评价试验项目建立仿真流程,选取关键的客观评价指标并与主观评价结果对比,建立整车操纵性能仿真客观评价体系。结果表明仿真结果与主观评价结果有很好的一致性。

According to the actual working conditions of the whole vehicle evaluation,the scientific six-component force test method was determined,and the PAC2002 model of the tire was established. According to the kinematics and dynamics test data of whole vehicle suspension and the test data of the steering system,the whole vehicle model of a brand SUV was established by Carsim software. According to GB/T 6323—2014 and subjective evaluation test items,the simulation process of the SUV was established,key objective evaluation indexes were selected and compared with subjective evaluation results,and the objective evaluation system of the whole vehicle handling performance simulation was established. The results showed that the simulation results were in good agreement with the subjective evaluation results.
