摘要
文中利用MSC.Nastran与Hyperworks有限元软件对履带装载机车架进行了动态特性有限元分析,以此对样机进行了修改,证明可以利用计算机来代替大量同类试验工作,保证了设计的快速性与准确性。
Utilizing the MSC. Nastran and Hyperworks finite element software this paper carried out finite element analysis of the dynamics characteristics on the frame of caterpillar loader. Modifications were carried out on the prototype by the use of this analysis, and it was testified that it is possible to use the computer to substitute numerous similar experimental works, thus guaranteed the rapidity and accuracy of design.
