Choosing the geometry parameters of the independent suspension reasonably is one of the important conditions to obtain the satisfied character of service. Its state of motion is related to handling stability, fort ability, handling of steering and the life of tire, ect. The subject es from the rear suspension of “optima” car which made by DYK Co. Ltd. The doublewishbone suspension can be a reasonable choice of spaceoriented bar articulated point. The location and orientation of the suspension arm length can produce suitable motions. This thesis first analyzes the consists and function of the doublewishbone suspension in the design, then checks the up and down of arms of the doublewishbone independent suspension, Thirdly, make a detailed consideration of the various ponents of the link between relations is made. I calculate the suspension on the basis of the natural vibration frequency, static suspension deflection and dynamic deflection and elastic characteristics of the suspension terms at last. On the basis of Analysis of the position and role of the size of the ponents in the doublewishbone independent suspension, with CAD software and Pro / E, respectively, 2D drawings and 3D product Modeling are made. We made an accurate and detailed structural analysis on the design, which provides the reference for optimal design of the doublewishbone suspension. The approach can improve the performance of the doublewishbone independent suspension.Keyword: doublewishbone suspension。 Design。 錄1 前言14 懸架的功用和組成4 汽車懸架的類型63．懸架主要參數(shù)的確定8 懸架的動撓度 9 后懸架螺旋彈簧剛度及應(yīng)力計算13 設(shè)計要求13 雙橫臂式獨立懸架導(dǎo)向機(jī)構(gòu)設(shè)計20 分類20 減振器阻尼系數(shù) 的確定22 簡式減振器工作缸直徑D的確定24 關(guān)于Pro/E27 本章小結(jié)28參考文獻(xiàn) 謝 錄本試驗臺實現(xiàn)的是懸架的剛度可調(diào)。本試驗臺由空氣壓縮機(jī)、濾清器、安全閥、空氣彈簧、減振器和其它的相關(guān)部件組成機(jī)械振動系統(tǒng)，由傳感器、ECU和執(zhí)行元件組成測控系統(tǒng)，利用傳感器采集信號，通過計算機(jī)處理，控制高度閥和步進(jìn)電機(jī)，從而使簧上質(zhì)量的高度和振動頻率都在一定的范圍之內(nèi)。關(guān)鍵詞：汽車振動，空氣彈簧，可控空氣懸架，懸架試驗臺AbstractThe thesis according to the theory which simplifies about the model of vehicle, on the base of a quarter car simulation suspension mechanism rig, the ordinary helical spring is replaced by an air spring, and the air suspension testing rig have been designed.The test rig put the suspension rigidity adjustment into practice.
