特种装备专用应急起重装置轻量化设计

根据某特种装备使用、维护和维修的需要,明确该设备专用应急起重装置的设计基本要求,确定总体方案设计。利用有限元软件ANSYS对该起重装置整体结构进行有限元分析,验算整体结构的强度。引入轻量化设计理念,对该专用应急起重装置整体结构进行结构优化,大梁侧板进行了重点的减重处理。有限元分析结果表明,新设计的应急起重装置总体结构在满足强度要求的同时,整体重量从原结构方案的220 kg减轻到181 kg。

Lightweight Design of Special Emergency Lifting Device of a Special Equipment

In according to the needs of use, maintenance and repair of a special equipment, and make clear the basic requirements of design of special emergency lifting device of a special equipment, the paper introduced the overall plan of design of this special emergency lifting device. Proceeded to finite element analysis on this lifting device with software ANSYS and checked the intensity of overall structure. Introduced a concept of lightweight design and carried on structure optimization on overall structure of this special emergency lifting device and focused on weight reduction on side plate of girder. The finite element analysis results show that the new design of overall structure of the emergency lifting device can meet the required intensity and at the same time the whole weight can reduce from 220 kg to 181 kg compare with the original project.
