Lightweight Design and Research of Hydraulic Excavator Arm Based on ABAQUS

液压挖掘机作为一种传统的大型机械工业设备,在机械行业发展进程中,随着理念的改变,人们对发展的要求更加倾向于低碳环保、节能减排。因此如何通过某些优化手段与设计方法,使得在不降低相关部件性能的情况下,减少能源消耗,提高综合性能成为相关领域研究的重点,液压挖掘机的轻量化研究被广泛关注。本文根据挖掘机在工作中的运动以及运作时的复杂工况进行研究,同时通过静力学分析,对挖掘机小臂提出轻量化设计方案,结合优化要求,再通过有限元分析软件ABAQUS相关模块的精密计算得到相应的优化模型。最后,对优化后的模型进行强度与刚度等的计算,以此保证轻量化的合理性。

As a traditional large-scale mechanical industrial equipment,in the development process of the mechanical industry,due to the general requirements of the society for the industrial industry and the improvement of the performance requirements,the lightweight research of hydraulic excavators has been widely concerned.In this paper,according to the movement of the excavator at work and the complex working conditions during operation,the lightweight design scheme of the excavator arm is proposed through static analysis.Based on this,combined with the optimization requirements,the corresponding optimization model is obtained through the precise calculation of the relevant modules of the finite element analysis software ABAQUS.Finally,the strength and stiffness of the optimized model are calculated to ensure the rationality of lightweight.
