摘　　要：目的以某重型装备的运输用框架结构为研究对象,提出工程轻量化的设计准则及设计方案,以解决重型装备过度包装的问题。方法利用Ansys软件对运输用钢架包装箱的起吊工况和堆码工况进行数值仿真分析,并基于分析结果对经验设计方案进行改进。结果优化后的钢架箱质量减少了942kg,质量减少比例达到了43%,起吊工况静强度安全系数为2.14,堆码工况静强度安全系数为1.94,稳定性安全系数有4.96倍。结论工程轻量化设计后的钢架箱满足屈服强度失效准则和稳定性失效准则规定的安全性能,提高了材料的使用效率,包装成本显著减少。The work aims to propose design criteria and design program for lightweight engineering with frame structure of certain heavy equipment for transportation as the research object to solve the problem of excessive packaging of heavy equipment. Numerical simulation analysis was carried out on the lifting and stacking conditions of the steel frame packaging boxes for transportation with software Ansys. The empirical design plan was improved based on the analysis results. The weight of the optimized steel frame box was reduced by 942 kg, and the weight reduction ratio reached 43%. The static strength safety factor of the lifting condition was 2.14, while the static strength safety factor of stacking condition was 1.94. The safety factor of stability was 4.96 times. The steel frame box of engineering lightweight design meets the safety performance specified by the yield strength failure criterion and the stability failure criterion, which not only improves the use efficiency of materials, but also significantly reduces the packaging cost.
