摘 要
挖掘機(jī)結(jié)構(gòu)非常復(fù)雜,往往是多發(fā)動(dòng)機(jī)同時(shí)驅(qū)動(dòng),其工作環(huán)境惡劣,外載荷隨機(jī)性變化,因此在設(shè)計(jì)大型礦用挖掘機(jī)時(shí),為了使其能夠作業(yè)安全,工作順暢,除必要的理論分析和靜強(qiáng)度計(jì)算外,還必須要進(jìn)行動(dòng)力學(xué)分析和有限元分析,以保證在設(shè)計(jì)之初機(jī)械的動(dòng)強(qiáng)度及可靠性。

ABSTRACT
The construct of excavator is very complex and the multiple movers often work simultaneously. At the same time its working environment is very bad and the eternal load varies randomly. As a result, when designing the new product of excavator, in order to ensure the performance safety, the designer not only has the basic theory analysis on static load computing, but also do necessary work about the kinetics of mechanism to qualify the dynamic reliability in the period of designing.
The first novel is devoted to write the development of domestic and theforeign excavators, As well as the study of the subject content and significance.To meet ou- rs development requires, this paper make dynamics simulation and finite element a- nalysis of mining excavator equipment which capacity is 27 m3. It introduced the s- tructure of the mechanical shovels, and analyzed the structure of its working equeq- uipment. According to the empirical formula to determine of the equipment structu- re size, and the various components size.Then briefly introduced the process of esta blishment of the working equipment, and evelopment of the used software also inc- luding its applicational charactistic , then lead the model of working equipment est- ablished in the UG to ANSYS.then introduced the software ANSYS in the static a- nalysis .Contra pose the working equipment of excavator in different conditions in the working, it analyzed the work force of the model by static analysis device to get the stress changes and the maximize location of unit. Then it is the conclusions of the full text . Our future tasks is to establish the effectiveness of virtual prototyping evaluation mechanism, to combine data of physical prototype simulation analyze the errors causes and research a fault-tolerant Virtual Prototyping System to ensure that the test data is credible, and any potential errors can be quantified.
