驅(qū)動橋設計與分析的理論研究現(xiàn)狀
隨著測試技術(shù)的發(fā)展與完善，在驅(qū)動橋設計過程中引進新的測試技術(shù)和各種專用的試驗設備，進行科學實驗，從各方面對產(chǎn)品的結(jié)構(gòu)、性能和零部件的強度、壽命進行測試，同時廣泛采用近代數(shù)學物理分析方法，對產(chǎn)品及其總成、零部件進行全面的技術(shù)分析、研究，這樣就使驅(qū)動橋設計理論發(fā)展到以科學實驗和技術(shù)分析為基礎的階段。
(1)計算機支持驅(qū)動橋設計與分析的理論創(chuàng)新：
電子計算機在工程設計中的推廣應用，使驅(qū)動橋設計理論與技術(shù)飛躍發(fā)展，設計過程完全改觀。驅(qū)動橋結(jié)構(gòu)參數(shù)及性能參數(shù)等的優(yōu)化選擇與匹配、零部件的強度核算與壽命預測、產(chǎn)品有關(guān)方面的模擬計算或仿真分析即更進一步的美工造型等等設計方案的選擇及定型，設計圖紙的繪制，均可在計算機上進行。采用電子計算機作分析計算手段，由于其計算速度很快且數(shù)據(jù)容量很大，就可采用較準確的多自由度的數(shù)學模型來模擬驅(qū)動橋在各種工況下的運動，采用現(xiàn)代先進的數(shù)學方法進行分析，可取得較準確的結(jié)果，這就為設計人員分析多種方案進行創(chuàng)造性的工作提供了很大的方便。當前，由于計算機的外部設備及人機聯(lián)系方面的成就，已可將計算機的快速計算和邏輯判斷能力、大容量的數(shù)據(jù)儲存及高效的數(shù)據(jù)處理能力、計算結(jié)果的動態(tài)圖像顯示功能與人的創(chuàng)造性思維能力及經(jīng)驗結(jié)合起來，實現(xiàn)人機對話式的半自動化設計，或與產(chǎn)品設計的專家系統(tǒng)相結(jié)合，實現(xiàn)自動化設計。其設計過程可由電子計算機對有關(guān)產(chǎn)品的大量數(shù)據(jù)、資料進行檢索，對有關(guān)設計問題進行高速的設計計算，通過計算機屏幕顯示其設計圖形和計算結(jié)果;設計人員可用光筆和人機對話語言直接對圖形進行修改，取得最佳設計方案后，再由與計算機聯(lián)機的繪圖設備繪出產(chǎn)品圖紙。這種利用計算機及其外部設備進行產(chǎn)品設計的方法，統(tǒng)稱為計算機輔助設計。今后CAD將與CAM結(jié)合成CADMAT系統(tǒng)，更將顯示出其巨大的功用。
(2) 基礎學科支持驅(qū)動橋設計與分析的理論創(chuàng)新：
隨著計算機在驅(qū)動橋設計中的推廣應用，一些近代的數(shù)學物理方法和基礎理論方面的新成就在汽車設計中也日益得到廣泛應用?，F(xiàn)代驅(qū)動橋設計，除傳統(tǒng)的方法、計算機輔助設計方法外，還引進了最優(yōu)化設計、可靠性設計、有限元分析計算機模擬計算或仿真分析、模態(tài)分析等現(xiàn)代設計方法與分析手段。驅(qū)動橋設計與分析理論達到當前的高水平，是百余年來特別是近三十年來基礎科學、應用技術(shù)、材料與制造工藝不斷發(fā)展進步的結(jié)果，也是設計、生產(chǎn)與使用經(jīng)驗長期積累的結(jié)果.它立足于規(guī)模宏大的生產(chǎn)實踐，以基礎理論為指導，以體現(xiàn)當代科技成就的驅(qū)動橋設計軟件及硬件為手段，以滿足社會需求為目的，借助于材料、工藝、設備、工具、測試儀器、試驗技術(shù)及經(jīng)營管理等領(lǐng)域的成就，不斷地發(fā)展進步.
(3) 逆工程理論與方法得到廣泛的應用：
在驅(qū)動橋自動化制造領(lǐng)域中，常常涉及大量的復雜曲面設計制造與檢測。通常情況下，首先在計算機上應用計算機輔助設計及制造技術(shù)進行產(chǎn)品模型設計，然后生成數(shù)控代碼進行加工。與這種傳統(tǒng)的加工模式相比較，逆工程表示了一種CAD模型不存在的產(chǎn)品設計方法，而是通過從各種方式獲得的實物模型中抽取數(shù)據(jù)進行再設計的一種開發(fā)模式有產(chǎn)品的修改。驅(qū)動橋殼設計與制造就是一種非常典型的逆工程設計方法。
(4)快速原型技術(shù)應用：
產(chǎn)品創(chuàng)新設計是充分發(fā)揮設計者的創(chuàng)造性想像才能，利用有關(guān)技術(shù)知識和技術(shù)原理進行創(chuàng)新構(gòu)思的一種實踐活動，其目的是創(chuàng)造性地設計出富有新穎性和先進性的產(chǎn)品。在傳統(tǒng)設計開發(fā)中，其過程分為方案設計、技術(shù)設計、工藝設計和產(chǎn)品制造.隨著計算機信息技術(shù)的發(fā)展，產(chǎn)品設計開發(fā)的范疇已經(jīng)從傳統(tǒng)的內(nèi)容擴展到產(chǎn)品規(guī)劃、制造、檢測、試驗、營銷以及回收全過程。傳統(tǒng)的設計，延長了產(chǎn)品開發(fā)周期?？焖僭图夹g(shù)是將CAD模型逐層完成實體模型的制造技術(shù)，快速原型技術(shù)徹底擺脫了傳統(tǒng)的加工方法，采用全新的增長加工方法，將復雜的三維加工分解為簡單的二維加工的組合。因此它不必采用傳統(tǒng)的加工機床和加工模具，而只需要傳統(tǒng)加工方法10%一30%的工時和20%一30%的成本就能直接制造出產(chǎn)品樣本和模具。在產(chǎn)品創(chuàng)新設計開發(fā)中應用快速原型技術(shù)，用現(xiàn)代的高科技手段和技術(shù)來改造傳統(tǒng)的產(chǎn)品設計開發(fā)方法，能夠促進設計創(chuàng)新、產(chǎn)品創(chuàng)新、工藝創(chuàng)新和管理創(chuàng)新，形成數(shù)字化、虛擬化、智能化、集成化，從而帶來了產(chǎn)品設計開發(fā)的革命。
(5) 并行工程應用到產(chǎn)品的管理與開發(fā)：
驅(qū)動橋產(chǎn)業(yè)己在世界范圍內(nèi)展開了劇烈的競爭，縮短新產(chǎn)品的設計一開發(fā)時間、降低成本、提高質(zhì)量、提高市場競爭力，日益成為各制造廠家考慮的首要問題。并行工程作為現(xiàn)代的、先進的產(chǎn)品設計開發(fā)模式，是解決上述問題的好辦法，己為各國汽車制造業(yè)所采用。所謂并行工程，是集成、并行設計產(chǎn)品及相關(guān)過程的系統(tǒng)工程，它考慮到產(chǎn)品從概念設計、設計定型、制造、使用、維修直至報廢這一全過程中的所有相關(guān)因素，能解決因設計與制造工藝脫節(jié)而引起的設計改動頻繁、開發(fā)時間長、成本高等矛盾可最大限度地提高設計質(zhì)量和開發(fā)效率，提高產(chǎn)品的市場竟爭力。并行工程的關(guān)鍵是對產(chǎn)品及其相 關(guān)過程實行集成的并行設計，面向制造與裝配的設計是并行工程的重要內(nèi)容，在產(chǎn)品開發(fā)的整個過程中，設計是關(guān)鍵。產(chǎn)品的先天質(zhì)量決定于設計。統(tǒng)計表明， 產(chǎn)品在包括原材料、制造、使用、維修等各方面的花費即廣義成本的70%也是由設計階段決定。并行工程的目標就是盡量早地在設計階段就引入制造與裝配等工藝的約束，例如材料的選擇、制造工藝性、裝配性等約束，使設計方案的修改盡可能地在 產(chǎn)品開發(fā)的前期進行，減少從制造到裝配時發(fā)生的不利情況，使產(chǎn)品設計一次成功 ，避免在產(chǎn)品開發(fā)后期因改變設計而造成的巨大浪費，這就對驅(qū)動橋設計與分析理論的目標提出了更苛刻的要求。
