摇臂是装载机工作装置中重要的传力件,要传递较大的转斗缸作用力。针对客户反馈的某机型摇臂在使用过程中出现早期断裂的情况,利用有限元方法对其结构强度进行分析,找出危险截面,进行改进设计。首先在Pro/E中建立某机型摇臂三维实体模型,将其模型另存为*.STP格式的中性文件,由ANSYS Workbench读取后进行网格划分,建立有限元模型,运用ANSYS Workbench对有限元模型进行结构强度分析,并与其他成熟机型摇臂进行对比;通过对比找出应力较大的危险部位,对其进行改进设计,使摇臂结构强度满足市场需求,提高产品质量,同时也为后续其他机型的摇臂设计提供参考。
The rocker arm is an important force transmission part in the working device of the loader, to transmit the larger acting force of the bucket cylinder. According to the customer feedback, a type of rocker arm appeared early fracture in the process of using the finite element method to analyze its structural strength to identify the dangerous cross-section, to improve the design. Firstly, a three-dimensional solid model of rocker arm of a certain model was established in Pro / E, and its model was saved as a neutral file in * .STP format. After being read by ANSYS Workbench, the mesh was divided and the finite element model was established. Using ANSYS Workbench The finite element model is used to analyze the structural strength and compare with other mature rocker arms. By comparing and identifying the dangerous parts with larger stress, the rock-arm structural strength can be improved to meet the market demand and improve the product quality. Meanwhile, Also provide follow-up for other models of rocker arm design.
