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)向傳動機(jī)構(gòu)作為研究對象,選擇對斷開點(diǎn)和節(jié)臂球銷的位置進(jìn)行優(yōu)化設(shè)計,在此基礎(chǔ)上建立了基于多體系統(tǒng)動力學(xué)的導(dǎo)向機(jī)構(gòu)和轉(zhuǎn)向傳動機(jī)構(gòu)的數(shù)學(xué)模型,運(yùn)用該學(xué)科的運(yùn)動學(xué)分析方法研究機(jī)構(gòu)的運(yùn)動規(guī)律,編制了通用優(yōu)化設(shè)計軟件。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)的空間動力學(xué)模型后,運(yùn)用多體動力學(xué)中的動力學(xué)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,并開發(fā)出了相應(yīng)的通用計算程序。
