In this paper, ackerman steering linkage of double - wishbone suspension is taken as the study object, choosing the splitting joint and steering lever joint to carry out the design of optimization the mathematics models are established based on the multi - body system dynamics, applying its analysis method of kinematics to study the mechanism kinetic principles owing to more spatial factors considered, and calling off many hypotheses affecting the accuracy, compared with the traditional methods, the models are better to reflect the realistic motion principles, the results are more exact and applicable moreover, the force analysis is applied to the conduct mechanism the analysis method of dynamics in the multi - body dynamics is applied to study the forces applied on every component, working out the constraint reaction force of up and down ball joints, and developing the current computation program in the end, produce the upper wishbone geometry model in the ansys software package, meshing and carrying out the fea, testifying if the intensity of the wishbone meet with the requirements
本文以雙橫臂獨立懸架的轉向傳動機構作為研究對象，選擇對斷開點和節臂球銷的位置進行優化設計，在此基礎上建立了基於多體系統動力學的導向機構和轉向傳動機構的數學模型，運用該學科的運動學分析方法研究機構的運動規律，編制了通用優化設計軟體。由於考慮了更多的空間因素，取消許多影響準確性的假設，因此建立的數學模型與傳統的方法相比更能反映實際運動規律，得到的優化結果也更加精確實用。此外，本文還針對導向機構進行受力分析，在建立該機構的空間動力學模型后，運用多體動力學中的動力學分析方法研究各個桿件的受力，計算出上下球鉸的約束反力，並開發出了相應的通用計算程序。 -

Against the way so called " top to down " by which most of the educational study deduct the certain theory, this paper prefers to use the collaboration of the way of " top to down " and the way of " bottom to up ", but the preferable way is " bottom to up " : i go near the world of the teacher ' s life, listen to the voice of the teacher, i make an attempt to keep the teacher ' s real situation, motion, chance and feeling, i welcome to invite readers to give an ear to their stories and understand the teacher ' s personal practical theory, also, expect me to do tiny but deep - ground task for verbalism in the educational study by standing the position on the chinese reality
與當前教育研究中大量的從既有理論框架中推演出某種論點並加以論證的所謂「自上而下」的方式不同，本研究更傾向于採取「自下而上」與「自上而下」相結合併以前者為主的策略：走近教師的生活世界，傾聽教師的聲音，用敘事的方式盡可能保留實踐中的情境、流動、機緣、感受，邀請讀者一同傾聽故事，並以此為基礎展開對教師個人實踐理論的理解，也期望通過立足中國現實土壤的研究為教育研究本土化做一點哪怕微不足道卻是扎實的工作。 -
