6m圆盘造球机机架轻量化设计

Lightweight Design of 6m Disc Pelletizer Frame

摘要: 本文为减轻圆盘造球机的重量，节约制造成本，提出一种对机架进行轻量化设计的思路。本文利用ANSYS workbench为平台，对造球机的整体及机架(支架和底座)进行应力分析，分析认为造球机的机架设计冗余量较大是造成设备重量增加的主要原因；因此以降低机架重量为目标，对机架进行轻量化设计，对优化后的机架结构进行比较，其结果表明最大等效应力降低10%，薄弱部件静刚度提升了10%，同时减轻设备质量1000 kg，既达到了轻量化的目的，又提升了其静刚度和强度，有效的降低设备的重量和制造成本既改善性能。为以后机架底座的设计提供了理论支持和设计参考。

Abstract: In order to reduce the weight of the disc pelletizer and save the manufacturing cost, this paper puts forward an idea of lightweight design of the frame. In this paper, the stress of the whole and the frame (bracket and base) of the pelletizer is analyzed by using ANSYS workbench as the platform. It is concluded that the large redundancy in the frame design of the pelletizer is the main reason for the increase of the weight of the equipment. Therefore, with the goal of reducing the weight of the rack, the lightweight design of the rack is carried out, and the optimized frame structure is compared. the results show that the maximum equivalent stress is reduced by 10%, the static stiff-ness of weak parts is increased by 10%, and the equipment mass is reduced by 1000 kg at the same time, which not only achieves the goal of lightweight, but also improves its static stiffness and strength, effectively reduces the weight of equipment and manufacturing cost, and improves performance. It provides theoretical support and design reference for the design of the frame base in the future.
