摘　　要：以一款粮食筒仓为研究对象,针对粮食筒仓在设计上结构冗余的问题,对其进行轻量化设计。首先对该粮食筒仓的仓壁、仓底和仓下支撑结构3部分进行静力学分析。根据静力学分析的结果,仓壁、仓底和仓下支撑结构仍有较大的优化潜力。因此,以减轻质量为目标,最大位移10 mm为约束条件,对粮食筒仓的尺寸参数进行改进。对其尺寸进行调整后重新进行分析,对比分析结果显示质量减轻了532.384 kg,减重比例达到14.18%,优化效果显著,为类似粮食筒仓的轻量化提供一定借鉴思路。Taking a grain silo as the research object,lightweight design is carried out to address the problem of structural redundancy in the design of grain silos.Firstly,three parts of the grain silo,the wall,the bottom and the support structure under the silo,are statically analyzed.According to the results of static analysis,there is still a large optimization potential for the silo wall,the silo bottom and the support structure under the silo.Therefore,with mass reduction as the objective and a maximum displacement of 10 mm as a constraint,the dimensional parameters of the grain silo are improved.After adjustment of its dimensions and re-analysis,the comparative analysis results show that the mass is reduced by 532.384 kg,with a mass reduction ratio of 14.18%,and the optimization effect is significant,which provides some reference ideas for lightweighting of similar grain silos.
