摘要
动臂是挖掘机的主要承力部件,在施工时会承受较大的交变复合应力和复杂的瞬态冲击载荷.基于CATIA软件建立挖掘机动臂的实体三维模型,并根据有限元分析结果制定动臂瞬时应力的检测方案.通过实测数据与有限元计算数据的对比,在验证有限元分析可靠性的基础上,优化动臂模型,指导实际生产.
The boom is the primary holding-force part of excavator, which bearing greater alternating complex stress and complex instantaneous impact load in the process of construction. The real 3D model of the boom was built by CATIA software, and the instantaneous stress test plan of the boom was formulated based on the finite element analysis. Through the comparison of experiment results and element analysis results, the reliability of finite element analysis was verified, which can optimize the model of boom and guide the actual production.
