目前对于煤矿用轮式推土机推土铲大臂系统的寿命评估工作主要是使用MSC-Fatigue软件分析法,结合疲劳耐久性集成化仿真分析流程确定其载荷谱,用实际大臂为研究对象对接头处进行疲劳试验,找出煤矿用轮式推土机推土铲大臂的裂纹扩展与使用寿命之间的关系,对起重机的剩余使用循环次数可以进行预测,可以对煤矿用轮式推土机推土铲今后的使用载荷有指导作用,减少发生事故的几率。
At present, the life assessment of bulldozer boom system for wheel excavators in coal mines mainly uses MSC-Fatigue software analysis method, combined with the fatigue durability integrated simulation analysis process to determine the load spectrum, with the actual boom for the study of the joint Department of fatigue test to find out the coal mine wheel dozer bulldozer boom crack propagation and the relationship between the life of the crane can be used to predict the number of remaining cycles can be used in coal mine wheel dozers future The use of load has a guiding role to reduce the chances of accidents.
