ZL50裝載機(jī)工作裝置CAD研究（本科畢業(yè)論文設(shè)計(jì)）
摘 要

裝載機(jī)是一種機(jī)動(dòng)靈活的工程機(jī)械，被廣泛應(yīng)用于各大廠礦以及工程施工場(chǎng)所。采用裝載機(jī)能夠提高效率，避免人力和物力的浪費(fèi)。目前，國(guó)內(nèi)各家工程機(jī)械廠及研究機(jī)構(gòu)已加強(qiáng)了對(duì)小型工程機(jī)械，尤其是裝載機(jī)、挖掘機(jī)的研究以適應(yīng)當(dāng)前的國(guó)內(nèi)市場(chǎng)需求，但國(guó)內(nèi)的研究水平與國(guó)外研究水平相比仍有一定的差距。為了研究開發(fā)經(jīng)濟(jì)高效的國(guó)民建設(shè)和工程施工設(shè)備，提高裝載機(jī)的技術(shù)性能，就有必要對(duì)裝載機(jī)工作裝置的結(jié)構(gòu)形式、運(yùn)動(dòng)過程進(jìn)行較為全面的計(jì)算分析，從而為其設(shè)計(jì)提供理論與技術(shù)支持。
本文主要介紹了三維CAD/CAM/CAE集成化設(shè)計(jì)軟件SolidWorks的功能和特點(diǎn)，運(yùn)用此軟件對(duì)ZL50裝載機(jī)工作裝置進(jìn)行虛擬實(shí)體建模和虛擬裝配，并通過其運(yùn)動(dòng)分析的插件Cosmosworks進(jìn)行有限元分析。

ABSTRACT

Loader is a kind of engineering machine with the features of simple and convenient maneuverability.It is widely applied to the diggings and construction place.The application of loader will improve the work efficiency and avoid the waste of manpower and material resources.In recent years,many research organizations in our country have been doing some research on the small size engineering machine,especially on loader and grab,in order to enhance the performance and the quality of these machines.Although we have made progress, there is a technology wide gap between our institute and aboard institute on study level.Therefore,in order to develop engineering construction equipments which aremore economical and more efficient,it is necessary to synthetically study the structure and motion of loader’s work device.The aim is to work out the computing analysis which is the basis of designing machines.
This article mainly introduced three dimensional CAD/CAM/CAE the integrated design software SolidWorks function and thecharacteristic, utilize this software to carry on the hypothesizedentity modelling and the hypothesized assembly to the ZL50 car loaderwork installment, and through its movement analysis plug-in unitCosmosworks, carries on the finite element analysis.


Key words： Loaders，working device，Solid modeling，Virtual Assembly，F(xiàn)initeelement analysis
