  1. Further acceleration only compounds the push, as weight shifts back to the rear drive wheels, off of the front turning wheels, leading to a further lessening of the car ' s ability to turn in

    此時如果進一步加速,只會加劇推頭,因為重量轉移到后輪,前輪(轉向輪)承受的重量減少,導致車輛的轉向性能變差。
  2. 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的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的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的優化設計模型,並輔以靜撓度、動撓度、頻率、動載荷等非線性約束,使用序列二次規劃法,利用matlab編制優化程序,求得前後懸架垂直剛度的最優匹配值;此優化模型不僅包含動靜撓度及頻率和阻尼的限制,還考慮到汽車的行駛安全性和道路友好性,比文獻報道的只考慮部分約束的優化模型更切合實際情況。
