机车结构部件在不同线路工况下的载荷谱计算

Load Spectrum Calculation of Locomotive Structural Parts in Different Line Conditions

现有载荷谱编谱方法,只是编制机车结构在试验线路所受载荷谱。当机车在其他线路运行时,使用试验线路载荷谱对结构进行设计规范是不准确的。本文给出一种新的载荷谱编谱方法,通过对机车在试验线路上的测试,编制机车不同线路工况载荷谱,对机车结构部件提供更准确的设计规范。

Current loading spectrum method is only used to locomotive structure in the test line. When the locomotive is running on other lines, it is not accurate to use the load spectrum of the test lines to design the structure. In this paper, a new method of load spectrum is presented, through test of the locomotive on the test lines, making load spectrum of locomotive different working conditions, to provide a more accurate design specification for locomotive structural components.
