| 摘 要： | 为改进汽车运动性能、提高运动汽车的操纵稳定性.通过对新型三轮跑车实际样车的三维坐标测量,利用ADAMS/Car精确建立新型三轮跑车的整车虚拟样机模型,对其进行了稳态回转特性试验、蛇形试验以及双移线试验等.仿真试验结果表明:横向稳定杆对新型三轮跑车的整车操纵稳定性影响最大,其次是质心高度对车操纵稳定性的影响.从理论上研究和分析车的操纵稳定性,确定车加装横向稳定杆以及使质心位置降低后会显著改善该车的操纵稳定性.

| Abstract: | To improve the athletic performance of automobile and the handling stability of sports car,based on the 3D coordinate measurement on the sample car,the virtual prototype model of a new type three-wheel sport car was precisely built in ADAMS/Car,and the steady turning test,snaking test and double lane change test on it were carried out. According to the simulation results,anti-roll bar has the biggest influence on handling stability,and the height of center of mass has big influences on handling stability as well. Research and analysis on the handling stability of this kind of car by theory confirm that installing anti-roll bar and reducing the height of center of mass can improve the handling stability of the car remarkably. |
