平地机后机架工况分析与试验测试

平地机后机架是整机的主要结构件,其整体刚强度决定了整机的应用范围及工作能力.通过分析计算得出了平地机后机架受力状况恶劣的两种实际工况,并运用有限元分析法,得出了恶劣工况下,后机架上的危险区域分布,最后用模拟工况试验的方法得出了不同工况下危险区域的应力数值,验证了分析计算结果,同时也为平地机后机架的结构设计提供了依据.

Work Conditions Analysis and Test on Rear Frame of Grader

Rear frame of grader is important structure in the whole machine,whose integral rigidity would decide range of application and work capability of the entire grader.2 cases of adverse working conditions while the rear frame is stressed have been found out thru analyses and computation.The findings also indicate risk distribution over the rear frame under adverse operational conditions.Finally,we get stress values at the risk areas under various work conditions thru tests using the work conditions simulation,...
