【摘要】 基于UG三维建模软件对矿用WK-75型挖掘机行走底架进行数字化建模,求得各个部件的重量及部件重心位置,通过MATLAB软件对简化后载荷矩阵进行求解,并应用有限元软件对装置工作过程中底架可能出现最大应力的3种不同工况下进行数值模拟分析。模拟结果表明:工况1和工况2受力远小于Q460E钢板材料许用应力,工况3所受应力与Q460E钢板材料许用应力接近,加厚底架钢板后,可以提高底架的抗载荷能力和抗变形能力。更多还原

【Abstract】 Based on the UG 3 D modeling software, the WK-75 excavator walking frame is digitally modeled and the weight of each component and the center of gravity of the parts are obtained. The simplified load matrix is solved by MATLAB software and the finite element. The simulation results show that the stress of the working condition and the working condition is much less than that of the Q460 E steel plate, and the working conditions of the Q460 E steel plate are much lower than those of the Q460 E steel plate. Stress and Q460 E steel plate material close to the stress, thicken the chassis plate,can improve the anti-load capacity of the chassis and anti-deformation ability.更多还原
