摘 要
本設計是基于ADAMS/view雙橫臂獨立懸架的仿真與優(yōu)化，利用ADAMS多體力學軟件建立雙橫臂獨立懸架的多剛體模型，通過對模型中的車輪施加運動約束從而對其進行運動性能的仿真分析，從而獲得該車輪定位角的變化，將其設計要求和分析結(jié)果對比，可以得出懸架結(jié)構(gòu)設計的合理性及需要改進的地方。
此外，對雙橫臂獨立懸架做了合理的簡化，建立了雙橫臂獨立懸架力學及虛擬樣機的模型，并在虛擬樣機軟件ADAMS/view模塊上進行仿真，在此基礎上對前懸架的各個參數(shù)進行優(yōu)化設計，使其得到懸架振動達到最優(yōu)值，從而為設計和改進提供快速、可靠的技術(shù)依據(jù)，達到大幅度降低設備研制成本，大大降低了輪胎的磨損情況的目的。

ABSTRACT
The design is simulation and optimization of double wishbone suspension based on ADAMS/view, we modeling the multi-rigid of Double-wish-bone Independent suspension by using the modtion view ,and then ,start the simulation after constraining the vehicle wheels and we can get the change of the vehicle location angle ,finally,compare the simulation result with the design requirement , we will find whether the tesultment the dement of design which performence should be improved.
Desides ,according to mechincs of vibration and dynamics of multi-body system ,a virtual prototype model of wishbone type independent front suspension was established model, the parameters of front suspension were optimized to minimize the vibration of front suspension. Thus, it provides a quick and reliable technical basis for designing and improveing, reduce cost of equipment developed and purpose of the tyre wear.
