In such a market demand of both urban walking, field sports, in line with modern young people to pursue an extremely strong personality of the mentality of SUV cars to be shipped and Health. SUV can adapt to all kinds of traffic, but also for suspension of fort and handling and stability also have higher requirements. The design of the SUV car suspension system is also in order to meet the current development of the actual needs of such a design. The design of major research SUV cars before and after the suspension system of structural design. Before the current suspension of the more popular Maifuxunshi independent suspension system, rear suspension better use of forttwolink independent suspension. Before and after the suspension of the shock absorber have adopted a twoway roleShock Absorber. This structure of the design and effective use of the improved fort and driving stability. Also in the design of a suspension parameters of the flexibility of the design elements, the orientation and structure of the horizontal Wending Gan calculation and strength checking. Moreover, the use of Matlab software on the ride suspension system of a programming analysis, demonstration of the system design of reasonable accuracy, to meet the actual needs. The design for improving the car on ride fort, handling and stability problems have some practical significance. In addition to auto enterprises suspension design, with some reference value. Key words: independent suspension。 本設(shè)計(jì)對(duì)于提高汽車行駛平順性、操縱穩(wěn)定性等問題具有一定的的實(shí)際意義。 在此次設(shè)計(jì)中還進(jìn)行了懸架參數(shù)的確定、彈性元件的設(shè)計(jì)計(jì)算、導(dǎo)向機(jī)構(gòu)和橫向穩(wěn)定桿的結(jié)構(gòu)計(jì)算及強(qiáng)度校核。前、后懸架的減振器均采用雙向作用式筒式減振器。 本次設(shè)計(jì)主要研究 SUV 轎車的前、后懸架系統(tǒng)的 結(jié)構(gòu) 設(shè)計(jì)。 SUV 能適應(yīng)各種路況 ,而且對(duì)于 懸架的 舒適性和操縱穩(wěn)定性也有更高的要求。 本科生畢業(yè)設(shè)計(jì)(說明書) I 摘 要 隨著汽車工業(yè)和減振器行業(yè)的發(fā)展以及生活條件的改善 ,人們對(duì)汽車 的要求已經(jīng)不僅僅局限于通行 ,乘客對(duì)汽車的運(yùn)動(dòng)性也提出了更高的要求。在這種市場(chǎng)需求下一種 兼具城市行走、野外運(yùn)動(dòng),極其符合現(xiàn)代年輕人追求強(qiáng)烈個(gè)性的心態(tài)的 SUV 轎車應(yīng)運(yùn)以而生。 這次設(shè)計(jì)的 SUV 轎車懸架系統(tǒng)也是為了適應(yīng)發(fā)展當(dāng)前的這種實(shí)際的需要而設(shè)計(jì)。前懸架采用目前較流行的麥弗遜式獨(dú)立懸架系統(tǒng),后懸架采用 舒適性較好的 二連 桿式非 獨(dú)立懸架。這種結(jié)構(gòu)的設(shè)計(jì),有效的提高了乘座的舒適性和駕駛穩(wěn)定性。 而且,采用 Matlab 軟件對(duì)懸架
