| 摘 要： | 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.

| Abstract: | Based on vector algebra method and using finite rotation tensor,a kinematic model for suspension 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 optimization,the coordinates of suspension hard-points meeting different pref... |
