摘要
利用拓扑优化技术对EBZ220M-2型掘锚一体机的截割臂进行了结构改进。首先,利用Creo和Hyperworks软件建立截割臂的拓扑优化模型,通过分析发现,截割臂不同位置的单元密度差异性很大。然后,根据拓扑优化结果,从4个层面优化改进截割臂的结构。改进后的截割臂应力虽然有所增加,但仍满足使用要求,同时质量减轻了11.3%,可实现成本降低和后期运行能耗降低的效果。将新的截割臂应用到工程实践中,经验证,达到了预期效果,经济效益显著。
The cutting arm of EBZ220M-2 excavator anchor integrated machine was structurally improved using topology optimization technology.Firstly,a topology optimization model for the cutting arm was established using Creo and Hyperworks software.Through analysis,it was found that there is a significant difference in unit density at dfferent positions of the cutting arm.Then,optimize and improve the structure of the cutting arm from four levels based on the topology optimization results.Although the stress of the improved cutting arm has increased,it still meets the usage requirements,and the weight has been reduced by 11.3%,which can achieve the effect of cost reduction and energy consumption reduction in later operation.The application of the new cutting arm in engineering practice has been verified to achieve the expected results and significant economic benefits.
