12、嚴(yán)格全面的道路試驗(yàn)規(guī)范。,試驗(yàn)規(guī)范,20,試驗(yàn)規(guī)范,21,原則：測(cè)試過(guò)程中，確保試驗(yàn)數(shù)據(jù)的可靠與準(zhǔn)確性。（為了確保數(shù)據(jù)質(zhì)量， 在正式測(cè)試之前，進(jìn)行一個(gè)試測(cè)。試測(cè)的工況可以選擇加速+制動(dòng)+轉(zhuǎn) 向的工況，然后進(jìn)行數(shù)據(jù)檢查和校隊(duì)。）,測(cè)試原則,六分力傳感器輸出信號(hào),22,左右懸架位移信號(hào),左前輪軸頭三向加速度信號(hào),23,左前輪軸頭三向加速度信號(hào),24,汽車在行駛過(guò)程中，不平路面的激勵(lì)以及駕駛員輸入（轉(zhuǎn)向，加速，制動(dòng)）將

13、導(dǎo)致汽車行駛狀態(tài)的變化。這種變化將使車輪載荷隨時(shí)間而變，進(jìn)而懸架各零部件之間發(fā)生相對(duì)位移。這種相對(duì)位移的產(chǎn)生源于懸架各零部件之間的動(dòng)態(tài)載荷所發(fā)生的相對(duì)變化，故而在行駛里程累計(jì)到一定程度后，某些零部件將會(huì)疲勞破壞。因此有效的獲取懸架零部件動(dòng)態(tài)載荷時(shí)間歷程，是分析和設(shè)計(jì)零部件耐久性能的重要工作。 一般來(lái)說(shuō)，懸架結(jié)構(gòu)強(qiáng)度和疲勞分析可以分為零部件級(jí)和系統(tǒng)級(jí)分析方法。 零部件級(jí)分析：采用多體動(dòng)力學(xué)方法得到懸架硬點(diǎn)載荷，對(duì)單一結(jié)構(gòu)進(jìn)

14、行分析的方法； 系統(tǒng)級(jí)分析方法：以整個(gè)懸架為基礎(chǔ)，同時(shí)考慮襯套、限位塊剛度以及零部件間相互運(yùn)動(dòng)的影響的分析方法。 零部件級(jí)分析方法原理簡(jiǎn)單，而且容易將分析過(guò)程流程化、規(guī)范化，從而保證分析結(jié)果的準(zhǔn)確性和一致性； 系統(tǒng)級(jí)分析方法，由于能夠考慮幾乎所有的懸架本身特性，如非線性連接關(guān)系、運(yùn)動(dòng)關(guān)系等特性，因而可以得到更為準(zhǔn)確的分析結(jié)果。,載荷分解,25,疲勞分析,26,疲勞分析五框圖,疲勞分析,27,轉(zhuǎn)向節(jié)單位載荷作用下應(yīng)
