摘要
针对目前人工精炼铝作业面临的工作环境恶劣、劳动强度大、工艺繁琐效率低等问题,综合考虑精炼铝车间布局和工艺技术要求,设计了一款集精炼、扒渣、清炉多功能于一体的新型自动化设备。为了保证设备具有较高的刚度质量比,对关键工作部件轮组式伸缩臂进行了参数化建模,基于响应面法对其结构尺寸进行了多目标优化设计,在保证足够工作刚度的条件下质量减轻45.6%,实现了结构的轻量化。对优化前后整体结构进行了有限元静力学仿真,分析结果表明优化设计后的总体结构相较于原方案而言,最大变形量减小了29.5%,最大Von Mises值减小了51.1%,总质量减小了8.2%,验证了所设计结构的合理性和优化方法的可行性。本研究可为类似金属炉内冶炼机械装置的设计与结构优化提供借鉴与参考。
Aiming at the problems of poor working environment,high labor intensity and low efficiency in manual refining of aluminum,considering the layout of refining aluminum workshop and technical requirements,a new automatic equipment integrating refining,slag removal and furnace cleaning was designed.In order to ensure the high stiffness-to-mass ratio of the equipment,the parametric modeling of the key working parts of the wheeled telescopic boom was carried out,and the multi-objective optimization de-sign of its structural size was carried out based on the response surface method.Under the condition of ensuring sufficient working stiffness,the mass was reduced by 45.6%,and the lightweight of the structure was realized.The finite element statics simulation of the whole structure before and after optimization was carried out.The analysis results showed that the maximum deformation was reduced by 29.5%,the maximum Von Mises value was reduced by 51.1%,and the total mass was reduced by 8.2%compared with the original scheme,which verified the rationality of the designed structure and the feasibility of the optimization method.This study can provide reference for the design and structural optimization of similar metal smelting machinery in furnace.
