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。Smart antenna may reduce coggege of electronic engineering of uestc, the cochannel interferences ( cci ), enhance the user capacity and spectrum efficiency, reduces the transmit power and electromagnetic interferences, enhance the transmit efficiency, dynamically divide cells in third generation cellular
智能天線技術應用於第三代移動通信系統中具有可以減小因頻率復用造成的共通道干擾( cci ) 、提高頻譜利用效率及增大系統容量、減小發射功率和空間電磁干擾、增加發射效率、對小區進行動態劃分等優點。The effective law on the frequence and modal of vibration due to the fluid velocity, the fluid press and the number of elements was obtained
