汽車變速器的三維造型與運(yùn)動(dòng)學(xué)仿真論文

摘 要：汽車變速器是整個(gè)汽車傳動(dòng)系統(tǒng)中相對(duì)關(guān)鍵的一個(gè)部件，變速器對(duì)整車的動(dòng)力性與經(jīng)濟(jì)性、操縱的可靠性與輕便性、傳動(dòng)的平穩(wěn)性與效率都有著較為直接的影響。以Pro/Engineer 5.0為工具，建立變速器各零部件的三維實(shí)體造型，根據(jù)它們之間的約束關(guān)系進(jìn)行整體裝配建模，檢測(cè)變速器整體模型中個(gè)零件之間的干涉情況，以確保運(yùn)動(dòng)仿真的順利進(jìn)行；在Pro/Mechanism模塊中建立變速器的運(yùn)動(dòng)仿真模型，動(dòng)態(tài)模擬變速器的整個(gè)工作過程。該方法實(shí)現(xiàn)了變速器設(shè)計(jì)階段的可視化，使原來在二維圖紙上難以表達(dá)和設(shè)計(jì)的運(yùn)動(dòng)變得非常直觀和易于修改，從而提高了汽車變速器的設(shè)計(jì)質(zhì)量和效率。

ABSTRACT: Auto transmission is the whole car transmission system, one of the crucial parts relative performance of vehicle transmission with economy, manipulating the reliability and portability, transmission and steadiness and efficiency have relatively direct influence. To Pro/e 5.0 for tools, set up the transmission of parts of three-dimensional molding, according to the constraint relation between them on the whole assembly modeling, detection transmission in a whole model between the parts, to ensure the interference of the motion simulation smoothly; In Pro/Mechanism in the module of establishing transmission, dynamic simulation motion simulation model of the whole process of the transmission. This method is realized the visual transmission design phase in the original 2d drawings to express and design sports become very intuitive and easy to modify, thereby improving the auto transmission design quality and efficiency.
Keywords： transmission,  entity modelling, assembly modeling, movement simulatio
