1. 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(dú)立懸架的轉(zhuǎn)向傳動(dòng)機(jī)構(gòu)作為研究對(duì)象，選擇對(duì)斷開(kāi)點(diǎn)和節(jié)臂球銷(xiāo)的位置進(jìn)行優(yōu)化設(shè)計(jì)，在此基礎(chǔ)上建立了基于多體系統(tǒng)動(dòng)力學(xué)的導(dǎo)向機(jī)構(gòu)和轉(zhuǎn)向傳動(dòng)機(jī)構(gòu)的數(shù)學(xué)模型，運(yùn)用該學(xué)科的運(yùn)動(dòng)學(xué)分析方法研究機(jī)構(gòu)的運(yùn)動(dòng)規(guī)律，編制了通用優(yōu)化設(shè)計(jì)軟件。由于考慮了更多的空間因素，取消許多影響準(zhǔn)確性的假設(shè)，因此建立的數(shù)學(xué)模型與傳統(tǒng)的方法相比更能反映實(shí)際運(yùn)動(dòng)規(guī)律，得到的優(yōu)化結(jié)果也更加精確實(shí)用。此外，本文還針對(duì)導(dǎo)向機(jī)構(gòu)進(jìn)行受力分析，在建立該機(jī)構(gòu)的空間動(dòng)力學(xué)模型后，運(yùn)用多體動(dòng)力學(xué)中的動(dòng)力學(xué)分析方法研究各個(gè)桿件的受力，計(jì)算出上下球鉸的約束反力，并開(kāi)發(fā)出了相應(yīng)的通用計(jì)算程序。
