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。 -

Through the studies of the invariants of the single axis motions, computational theories have been developed in this thesis to provide practical solutions for the problem of structure and motion from fitting the corresponding points in the whole sequence to its conic locus or conies for short. it is then shown that all single axis geometry can be directly computed either from one conic and one fundamental matrix or from at least two conies. the rotation angles then can be calculated directly from using the laguerre formula
本文通過詳細分析單軸旋轉運動中的不變量，利用物體點在單軸旋轉運動中軌跡為圓，而在圖象平面的投影為二次曲線的這一特徵，以二次曲線為分析的基元，研究了求解單軸旋轉運動結構問題的新理論和一系列新演算法，並在此基礎上完成了物體的三維重建等工作。 -
Because formation satellite ' s relative position is very close and the geometry can change easily, based on the relative motion of satellites, the initial phase bias could be quickly resolved simulation solution indicates that phase bias can be determined quickly and the relative states accuracy should be improved by using initial phase bias
由於編隊衛星相對距離近，相對構型容易改變，因此採用衛星相對機動的方式進行整周模糊度的快速初始化。模擬結果表明，基於衛星機動，整周模糊度可很快初始化。利用初始化的整周模糊度，相對狀態的解算精度會大大提高。 -
