采用有限转动张量,结合矢量代数法,建立了悬架导向机构的运动学数学模型,并对硬点作灵敏度分析.从提高操纵稳定性和降低轮胎磨损的角度出发,采用微型多目标遗传算法,对悬架跳动中轮心处侧向滑移量、车轮外倾角和前束角进行优化.结果表明,仪通过一次优化就能得到满足不同偏好的悬架硬点坐标.

Based on vector algebra method and using finite rotation tensor, a kinematic model for suspen-sion guiding mechanism is established, and the sensitivity analysis of hard-points is carried out. With the objectives of improving handling stability and reducing tire wear, the side slip of wheel center, wheel camber and wheel toe-in are optimized by using micro multi-objective genetic algorithm. The results show that with only a single run of opti-mization, the coordinates of suspension hard-points meeting different preferences can be obtained.
