JQ140G架桥机机臂有限元分析

Finite Element Analysis of the Arm Bridge-erecting Machine JQ140G

本文详细地分析了JQ140G铁路架桥机机臂的各种受力状况,并对其进行了有限元分析和强度测试,分别给出了分析结果和测试结果,对这两种结果进行了比较,认为机臂的有限元分析的结果是准确和可靠的,JQ140G铁路架桥机机臂的强度符合设计要求。

This article analyses each kind ofstress condition of thebridge horn of railroad armbridge-erecting machine JQ140G in detail, and carries on the finite element analysis and the intensity test to it and provides the analysing resultsand the test results separately. Based on the comparison of the two kinds of results, it figures out that the finite element analysis result is accurate and reliable and the intensity of the bridge horn of the arm bridge-erecting machine JQ140G conforms to the design requirement.
