电驱动方程式赛车转向操纵稳定性分析

Stability Analysis of Steering Maneuvering in Electrically Driven Formula Race Cars

对车辆来说,拥有良好的转向操纵稳定性是至关重要的,对方程式赛车尤为重要,对赛车进行转向操纵稳定性的分析与研究是每一支参赛车队都必须要做的。笔者首先对FSAE大学生方程式赛车在国内外的发展现状和方程式赛车操纵稳定性的影响因素进行简要说明,然后以学校参赛车队设计的电动方程式赛车的转向系统硬点坐标为基础,利用ADAMS/CAR虚拟样机对方程式赛车影响因子进行建模,并针对整车主要影响因子进行仿真分析、试验,输出仿真曲线,借助曲线结果的分析,对赛车操纵稳定性给予评价。

Having good steering stability is crucial for vehicles,especially for formula racing.Analyzing and researching the steering stability of racing cars is a must for every participating team.The author first provides a brief explanation of the current development status of FSAE college student formula racing at home and abroad,as well as the influencing factors on the handling and stability of formula racing.Then,based on the hard point coordinates of the steering system of the electric formula racing designed by the school's participating teams,the ADAMS/CAR virtual prototype is used to model the influencing factors of formula racing.Simulation analysis and experiments are conducted on the main influencing factors of the entire vehicle,and simulation curves are output,by analyzing the curve results,evaluate the handling and stability of the racing car.
