摘要
以某型号液压挖掘机作为研究对象,建立了挖掘机的三维模型,经格式转换后导入ADAMS软件中,添加驱动和约束后生成了主要工作部件的虚拟样机模型。仿真得出了挖掘机的整机极限工作范围,并进行了铲斗挖掘力分析,给出了各铰点力的仿真结果。在ADAMS软件协同环境下对其动臂进行有限元分析,给出了其应力和应变分布云图。通过对结果的分析验证了设计的合理性和正确性,为产品的后继开发及优化设计提供了可靠的依据。
A type of hydraulic excavator was choosed as the study object and its three-dimensional model was established. Then imported the model into ADAMS, the main working parts virtual prototype model e was generated by added drivers and constraints. The limit working range of the hydraulic excavator was got, after analyzing the digging force of the scraper pan, the simulation result of the force of each hinge points was given. The stress and strain distribution graph of the active arm was drew though the finite element analysis in ANSYS. The analysis of the results verified the rationality and correctness of the design, it provided a reliable basis for subsequent development and optimization of the product design.
