摘要
本文以车身垂直振动加速度均方根值最小为目标;轮胎与地面的附着性能、车身侧倾角、悬挂动行程和轮胎寿命在一定限制条件下作为约束,建立数学优化模型。采用单调性分析法优选悬挂刚度、阻尼系数及轮胎刚度。其优点是计算机程序极为简单,在一般微机上即可实现,结果也令人满意。
In the paper mathematical model for optimization of the vehicle suspension parametes has been built with the minimized mean square roots of vertical vibration acceleration of vehicle body as its objective function and simultan-eously with tyre-ground adhesion performance, vehicle inclination, verticaldisplacement of suspension dynamic state and limited tyre life as the constraints.The monotonicity analysis was applied to optimize the suspension stiffness, damping force coefficient and tyre stiffness. This method possesses advantageyielding a most simply computation program that may be implemeted on ordinary micro-computer with satisfactory result.
