【摘要】：雙離合自動變速器DCT（Dual Clutch Transmission）是目前世界上比較優(yōu)秀的自動變速箱之一，具有換擋平穩(wěn)、動力性好等優(yōu)點。新型自主研發(fā)自動變速箱的設計思想源于選擇性輸入雙離合自動變速器，在其基礎上以控制輸出替代控制輸入，并運用技術(shù)比較成熟的行星輪系系統(tǒng)以減小其檔位齒輪個數(shù)達到減小其軸向尺寸的效果。由于NSGA-Ⅱ為當今世界多目標進化算法中的一枝獨秀，具有精英策略、約束處理、無共享參數(shù)等優(yōu)秀性能，能很好的實現(xiàn)算法結(jié)果的收斂性和解的多樣性。運用莊家法則能快速減少對象和淘汰組員的優(yōu)勢與預排序構(gòu)造集元素不被它后面的元素所支配的特性，提出改進的NSGA-Ⅱ—基于預排序的莊家法則快速構(gòu)造非支配解集方法。本文主要圍繞該新型選擇性輸出自動變速器展開，，運用改進的NSGA-Ⅱ?qū)π行禽喯挡考脑O計進行優(yōu)化，得到最優(yōu)解。本文主要研究內(nèi)容如下； （1）介紹自動變速器的種類、特點、運用場合、發(fā)展現(xiàn)狀及其各自的工作原理并進行優(yōu)缺點對比。 （2）總結(jié)DCT的兩種分類方式及其特點，分析新型選擇性輸出DCT的結(jié)構(gòu)特點和工作原理，同時對行星輪系部件進行說明并介紹行星輪系設計時的原則和注意事項，介紹齒圈設計及加工過程中一些干涉。 （3）介紹遺傳算法，NSGA-Ⅱ,Pareto解及莊家法則，并給出改進NSGA-Ⅱ的算法步驟和選擇最優(yōu)解的方法。 （4）運用改進NSGA-Ⅱ的算法，對行星輪系進行優(yōu)化設計，提出目標函數(shù)及限制條件，運用Matlab工具進行編程得到Pareto解并通過計算得到最優(yōu)解。
[Abstract]:Double clutch automatic transmission DCT (Dual Clutch Transmission) is one of the automatic gearbox world relatively good at present, has advantages of good dynamic stability of the shift, etc. design new sources of independent research and development of automatic transmission in the selective input dual clutch automatic transmission, on the basis to control the output instead of the control input, and the use of planetary gear train system with mature technology to reduce the number of gears to reduce its axial size effect. Because the NSGA- II as one of the world's multi objective evolutionary algorithm in a thriving, with elite strategy, constraint handling, without sharing parameters such as excellent performance, good convergence and achieve results the diversity of use can quickly reduce the banker law advantage and pre sorting objects are constructed and eliminated members of the set of elements are not characteristic elements after the control, this thesis proposes an improved N SGA- II - non dominated solution set method for rapid construction of banker law based on pre ordering. This paper mainly focuses on the new selective output of automatic transmission, using the improved NSGA- design of planetary gear train components were optimized to obtain the optimal solution. The main research contents of this paper are as follows;
(1) introduce the types, features, applications, development status and their respective working principles of automatic transmission, and compare their advantages and disadvantages.
(2) two classification of DCT and its characteristics, analyses the structural characteristics and working principle of a new type of selective output DCT, the components of planetary gear train is described and the design of the planetary gear train the principles and considerations, some interference ring gear design and processing.
(3) introduce the genetic algorithm, NSGA- II, Pareto solution and the rule of the dealer, and give the algorithm steps to improve the NSGA- II and the method of choosing the optimal solution.
(4) use the improved NSGA- II algorithm to optimize the planetary gear train, and propose the objective function and the restrictive condition. We use the Matlab tool to program the Pareto solution and get the optimal solution by calculation.
