轮式装载机前车架的有限元分析与结构优化
Finite Element Analysis and Structural Optimization of the Front Frame of Wheel Loader
摘要
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%.关键词
