Fatigue Life Analysis of Working Mechanism for Mining Backhoe Loader-bucket
为了确定矿用挖掘式装载机工作机构的疲劳寿命,分析并确定了铲斗随机挖掘阻力的计算方法,利用Matlab模拟铲斗的随机挖掘阻力.采用Pro/E建立该机工作机构的三维模型,将其映射到Workbench环境中创建其有限元模型;将模拟的挖掘阻力数据导入ncode模块,分析铲斗、小臂和大臂的应力和疲劳寿命情况.结果表明:该机工作机构的应变量范围在0.313×10-2-0.028 m之间,应力范围集中在705-3.85×108Pa;铲斗与连杆的连接部位寿命最短…查看全部>>
In order to figure out the fatigue life of the working mechanism of mining backhoe loader-bucket,the calculation method of the random excavating resistance of bucket was analyzed and determined,and Matlab was applied to simulate the random excavating resistance.With Pro/E,the three-dimensional model of the working mechanism was established,and its finite element model was created by Workbench.The simulated excavating resistance was imported into ncode to ana…查看全部>>
