在汽车悬架结构优化设计问题的研究中,为了改善汽车前悬架的运动学特性,以某车型麦弗逊悬架为研究对象,研究麦弗逊悬架结构参数优化问题,从而减少轮胎磨损,提高汽车稳定性。根据车轮跳动原理和前轮定位参数变化规律,建立麦弗逊悬架动力学模型,采用免疫算法对麦弗逊悬架的结构参数进行优化,并进行实车验证。仿真结果和试验结果之间的误差小于10%,验证了优化方法的可行性。研究结果表明,优化后悬架的前轮定位参数及变化范围满足了理想的范围,改善了悬架性能,减少了轮胎磨损,同时提高了汽车稳定性。

In order to improve the kinematics of McPherson suspension, choose McPherson suspension for study target, research the problem of optimization about the structure parameters of McPherson suspension, then reduce tire wear and improve vehicle stability. Based on the principle of wheel hop and the law of front wheel alignment variation, establish the dynamics model of McPherson suspension, use immune algorithm to optimize the structural parameters of McPherson suspension, and give reasonable solution to test K＆C performances of vehicles. Error be...
