Papers detail the basic structure of the steering system, function, technical requirements and overall performance. At the same time, the steering rack and pinion, for a detailed layout and its spatial structure detailed analysis to determine the structure and arrangement of the steering, accurate analysis of the characteristics of the gear transmission and transmission efficiency. According to the data of cars which carry out design calculations determine the steering gear ratio and other geometric parameters. Thus, the use of 3 d modeling software PROE draw the steering parts, each part and draw the parts drawing. Further assembly。 e to its assembly drawing. On this basis, then, the conversion format, imported into ADMAS software for motion simulation. Age in progress, is also continuous development of science and technology, new technology, new material emerge in endlessly. Pinion and rack steering gear, in constant accumulation, has been constantly innovation, constantly toward portable, intelligent direction.Keywords: saloon car。 steering system。 pinion and rack。 steering gear。 transmission ratio安徽工程大學(xué)畢業(yè)設(shè)計(jì)（論文） 3 目 錄引言 .............................................................................................................................................6第一章 緒論 ...............................................................................................................................7 轉(zhuǎn)向系統(tǒng)的設(shè)計(jì)要求 .................................................................................................7 轉(zhuǎn)向器的功用及分類 .................................................................................................8 轉(zhuǎn)向器的功用 ................................................................................................8 轉(zhuǎn)向器的分類 ................................................................................................9 齒輪齒條轉(zhuǎn)向器的優(yōu)缺點(diǎn) ..........................................................................10 汽車轉(zhuǎn)向器國內(nèi)外現(xiàn)狀及發(fā)展趨勢 .......................................................................10 國內(nèi)外現(xiàn)狀 ..................................................................................................10 轉(zhuǎn)向系的發(fā)展發(fā)展趨勢 ..............................................................................11 設(shè)計(jì)的主要內(nèi)容 .......................................................................................................12第二章 轉(zhuǎn)向器的設(shè)計(jì)計(jì)算 .....................................................................................................13 轉(zhuǎn)向系主要參數(shù)的確定 ...........................................................................................13 轉(zhuǎn)向系傳動比的確定 ..................................................................................13 動力缸的設(shè)計(jì)計(jì)算 ......................................................................................15 齒輪齒條轉(zhuǎn)向器設(shè)計(jì)計(jì)算 .......................................................................................17 主要設(shè)計(jì)參數(shù)的選擇 ..................................................................................17 齒輪齒條參數(shù)的計(jì)算 ..................................................................................17 按齒根彎曲疲勞強(qiáng)度計(jì)算校核 ..................................................................18 按齒面接觸疲勞強(qiáng)度校核 ..........................................................................18第三章 轉(zhuǎn)向器三維模型的建立 .............................................................................................19 轉(zhuǎn)向器方向盤的建立過程 .......................................................................................19 齒輪齒條模型建立的過程 .......................................................................................22 小齒輪的建立過程 ......................................................................................22 齒條的創(chuàng)建 ..................................................................................................24 動力缸的建立 ..............................................................................................27 轉(zhuǎn)向器的裝配過程 ...................................................................................................28第四章 轉(zhuǎn)向器的運(yùn)動仿真分析 .............................................................................................30 軟件介紹 ........................................................................................30 三維模型的導(dǎo)入過程和定義約束 ...........................................................................31 模型的導(dǎo)入 ..................................................................................................31 定義約束 ......................................................................................................32 仿真實(shí)驗(yàn)與結(jié)果分析 ................................................................................................33結(jié)論與展望 ...............................................................................................................................36致謝 ...........................................................................................................................................37參考文獻(xiàn) ...................................................................................................................................38附錄 A 外文文獻(xiàn)及其譯文 ...................................................................................................39附錄 B 參考文獻(xiàn)及摘要 .......................................................................................................51插圖清單安徽工程大學(xué)畢業(yè)設(shè)計(jì)（論文） 4 圖 11 轉(zhuǎn)向系 .......................................................................................
