| 摘 要： | 以某ZL50装载机前车架为研究对象,利用Pro/E软件建立三维实体模型,导入ABAQUS软件建立有限元模型.基于载荷-时间历程的动态有限元分析,获得典型工况下的前车架应力分布云图.结果表明:在举升和卸载工况下,局部结构应力峰值过大,应力集中位置较多;在应力集中位置增设加强筋和过渡圆角,并对加强筋板厚度进行优化后,前车架受力状况得到明显改善,应力集中现象得以消除,安全系数提高近200%.

| Abstract: | Taking ZL50 loader as the research object, 3D model was created by the Pro/E software. By importing the model to the ABAQUS software, the finite element model was established. Based on the dynamic finite element analysis of the loading-time course, the stress distribution graph of the front frame under typical working conditions was obtained. The results show that the local structural stress peak was too large and stress concentration points were too many under lifting and unloading working conditions. Increasing the reinforcing rib and the transition fillet at the stress concentration points, and optimizing the thickness of the reinforcing rib, the stress status of the front frame was obviously improved. The stress concentration phenomenon was eliminated. The safety coefficient was improved about 200%. |
