  1. Because the different stiffness match of front and rear suspension is very influencing to the ride comfort, optimal model of ride comfort is developed, regarding the rms of driver ’ s acceleration as the objection, regarding the stiffness of front and back suspension as optimal variable, regarding quiet flexibility 、 dynamic flexibility 、 frequency and dynamic load as nonlinear constraints. by matlab program and using sqp, the optimal match of front and back suspension ’ s stiffness is achieved, this optimal model consider not only request of quiet 、 dynamic flexibility 、 frequency and damp, but also security of run and peace of road, it is closer to the fact than other models which only consider partial restriction

    由於前後懸架垂直剛度不同匹配對汽車行駛平順性影響較大,論文建立以駕駛員垂直加速度均方根值作為汽車行駛平順性優化目標值、以前後懸架垂直剛度作為優化變量優化設計模型,並輔以靜撓度、動撓度、、動載荷等非線性約束,使用序列二次規法,利用matlab編制優化程序,求得前後懸架垂直剛度最優匹配值;此優化模型不僅包含動靜撓度及和阻尼限制,還考慮到汽車行駛安全性和路友好性,比文獻報只考慮部約束優化模型更切合實際情況。
