【摘要】 本文查阅了大量关于汽车底盘的资料与文献,阐述了汽车底盘各系统的研究方法及概况,提出图解分析法及弹性系数法的概念及其理论;经过推导、计算与分析,建立了汽车底盘中转向系、传动系、制动系以及行驶系的数学模型。其次应用图解分析法及弹性系数法对各数学模型进行分析,总结了各参数对其所对应的目标参数或性能指标的影响程度以及影响特性,进而提出系统或机构最佳的改进方向和措施,本文所提出的分析方法对汽车设计或改型设计具有较大的实际意义。文章最后介绍了相似工程学的理论基础,应用系统相似分析与度量的方法对汽车底盘各系统结构模型进行了相似度的计算,通过改变系统相似特征值提高系统相似度。此方法有利于汽车的系列化、多样化及个性化的产品设计。更多还原

【Abstract】 Firstly,this paper collectes lots of data and information about chassis,and expatiates the analysis methods and research status about all of systems of chassis,puts forward the conception and theory of the graphic method and elastic coefficient method;erects the mathematic model of the chassis by illation , calculating and analyzing. Secondly,using the graphic method and elastic coefficient method to analyse the different mathematic models,summarise the different parameters influence property and level of aim-parameters or index.Furthermore,it makes sure the best orientation and puts forward the best improvement measure of the system or mathine.The result proves that the research method is useful and valuable to vehicle design or retrofit design.In the end,this paper introduces the theoretical basis of similarity engineering.Using the methods of similarity analysis and similarity measure to calculate the similarity of all of system structure models of chassis,improves the similarity through changing the similarity eigenvalue.This method is useful to design for serialized,versatile and individualized automobile products.更多还原
