| 摘 要： | 对比常见的4种独立悬架的运动学特性,研究独立悬架的运动学优化目标,设定对比分析的条件. 使用Pro/Engineer进行仿真并优化这4种悬架的运动学特性. 对比研究表明:双横臂式、四连杆式和五连杆式悬架的运动学特性相近且略优于麦弗逊式. 实验表明,车轮行程不大于250mm的普通轻型汽车悬架应满足车轮外倾角变化量小于1°,车轮前束角变化量小于0.1°,车轮侧滑量小于13mm.

| Abstract: | The kinematic characteristics of 4 popular independent suspensions are compared and the objectives of kinematic optimization of independent suspension are investigated.Conditions for comparison and analysis are defined.The kinematic characteristics of these 4 suspensions are simulated and then optimized using Pro/Engineer.The comparison showed that the kinematic characteristics of the "double wishbone" suspension,4-Link suspension and 5-Link suspension are similar and slightly better than the MacPherson suspension.It is proposed that for kinematic optimization,for the suspension of normal light vehicle where the travel of wheel is no more than 250 mm,the change of wheel camber angle should be less than 1 degree,the change of wheel toe-in angle should be less than 0.1 degree and the side-slip of the wheel should be less than 13?mm. |
