麥弗遜懸架的設(shè)計(jì)
摘要:為了提高汽車行駛的平順性和穩(wěn)定性, 本課題進(jìn)行了產(chǎn)品名稱為QF1020貨車前后懸架的設(shè)計(jì)。通過對(duì)課題內(nèi)容的分析, 并結(jié)合相關(guān)設(shè)計(jì)手冊(cè),進(jìn)行了方案設(shè)計(jì)與比較, 設(shè)計(jì)了麥弗遜前懸架, 鋼板彈簧后懸架。在設(shè)計(jì)中,首先,分析了麥弗遜獨(dú)立懸架的組成和功用;其次,進(jìn)行懸架的上各零部件強(qiáng)度的校核;第三,詳細(xì)考慮各部件之間的連接關(guān)系;最后在此基礎(chǔ)上進(jìn)行懸架自然振動(dòng)頻率,懸架靜撓度和動(dòng)撓度以及懸架彈性特性的計(jì)算。在分析麥弗遜懸架的組成和作用以及各零部件的尺寸確定的基礎(chǔ)上,再利用CAD軟件進(jìn)行二維制圖。此次的設(shè)計(jì)進(jìn)行了準(zhǔn)確的計(jì)算和詳細(xì)的結(jié)構(gòu)分析,為麥弗遜懸架的結(jié)構(gòu)優(yōu)化提供了依據(jù),從而在運(yùn)動(dòng)學(xué)和動(dòng)力學(xué)方面提高汽車的性能。

The design of McPherson suspension
Abstract:In order to enhance the automobile smooth running and the stability, This topic has carried on the suspension design of the Product Name of QF1020 vehicle. Through analyzing the topic content, and combine the correlation design handbook, carried on the plan to design and to compare, the McPherson strut front suspension , the leaf spring behind suspension and trapezium’s frame are designed. This thesis first analyzes the consists and function of the McPherson suspension in the design, then check the up and down of the suspension, Third, the various components of the link between relations is considered the suspension on the basis of the natural vibration frequency is calculated as well as static suspension deflection and dynamic deflection and elastic characteristics of the suspension terms at last. On the basis of Analysis of the composition and role of the size of the components in the two suspension, then to use CAD software, 2D software mapping .We make an accurate and detailed structural analysis on the design, which provides the?reference for optimal design of the suspension. The approach can enhance the?performance of the McPherson suspension and leaf spring behind suspension.
