摘 要
懸架是汽車上的重要總成之一,懸架的作用是彈性地連接車橋和車架,減緩行駛中車輛受到由路面不平引起的沖擊力,保證乘坐舒適和貨物完好,迅速衰減由于彈性系統(tǒng)引起的振動(dòng),使車輪按一定軌跡相對(duì)車身運(yùn)動(dòng)。懸架決定著汽車的穩(wěn)定性、舒適性和安全性,所以研究懸架成為研究汽車中的重要一個(gè)環(huán)節(jié),ADAMS軟件為研究汽車懸架運(yùn)動(dòng)學(xué)分析提供了幫助。本次畢業(yè)設(shè)計(jì)首先利用ADAMS軟件的View功能給定設(shè)計(jì)點(diǎn),創(chuàng)建懸架模型,通過(guò)測(cè)試懸架模型得到一些曲線和數(shù)據(jù),對(duì)比這些曲線和數(shù)據(jù)之后得出輪胎接地點(diǎn)的側(cè)向滑移量變化是影響懸架的重要因素。所以將目標(biāo)函數(shù)定為車輪接地點(diǎn)的側(cè)向滑移量。然后通過(guò)ADAMS軟件的后處理功能優(yōu)化前懸架模型,最后得出使輪胎接地點(diǎn)的側(cè)向滑移量變化最小的一組數(shù)據(jù)。從而達(dá)到優(yōu)化的效果。

Abstract
Suspense is one of the important parts in a car. Suspense serves as a role that connects the axles and frames in a much bouncing way which can kill the unavoidable shock when the car is on a unsmooth road, thus making sure that the goods in the car cannot be damaged as well as guaranteeing a better driving pleasure. It can quickly kill the shock from the bouncing system to let the wheel move a the course of the car. Suspense determines the stability, riding comfort, and safety. Therefore, analyzing the suspense becomes one of the greatest parts of the whole analysis. ADAMS software did a great help to the analysis of suspense kinematics.The design of ADAMS software first given design points, View function to create suspension model, through the test suspension model get some curves and data, contrast these curves and data that pick up the tyres after the change of lateral sliding site is the important factors affect suspension. So will the objective function as the wheels of lateral slippage pick site. Then through the ADAMS software post-processing function optimization model of the suspension, finally come to pick up the tire place lateral sliding the smallest quantity of set of data. This group of data is finally wanted results.
