摘要
针对飞行器建立一种实体单元螺栓建模的飞行器舱段径向连接结构有限元模型.然后考虑参数敏感性分析步骤构建结构质量优化设计流程.最后对不同舱段直径和舱段材料的飞行器径向连接结构进行优化设计,得到优化设计方案,并比较分析不同舱段材料性能的优劣.研究成果可为飞行器径向连接结构早期的无样本强度预测设计缩短设计周期并节省成本.
Abstract
At first,a finite element model of the radial connection structure of aircraft cabin based on the solid element bolt modeling is established.And then,a structural quality optimization design process considering the pa-rameter sensitivity analysis step is constructed.At last,the optimal design of the aircraft radial connection structure with different cabin diameters and cabin materials is carried out,and the optimal design scheme is obtained,and the advantages and disadvantages of the performance of different cabin materials are compared and analyzed.The research results can shorten the design cycle and save the cost for the preliminary design of radial connection struc-ture without sample strength.
