摘要
家用安全屋作为一种家庭用的避险设备,能够在紧急情况下有效地保障人身安全,因此其研究具有重要意义。首先对安全屋的舱体结构进行静载仿真分析,根据结果确定舱体壁厚、加强筋截面长度与宽度为优化参数,舱体最大变形与最大等效应力为首要优化目标,舱体质量为次要优化目标,利用UG与ANSYS Workbench的协同仿真进行多目标优化,得到一组最优解,并将优化前后的仿真结果进行对比,为家用安全屋的结构设计与优化提供理论依据。
As a kind of household hedge equipment, the household safe house can effectively protect the personal safety in case of emergency, so the study on it is important. In this article, firstly, static load simulation analysis of the safe house cab- in structure is carried on. According to the results, it could determine the cabin wall thickness, the length and width of rib section as the optimize parameters. Making the maximum deformation and the maximum equivalent stress of cabin as the pri- mary optimization goal, cabin quality as the secondary optimization goal, a set of optimal solutions could be obtained by using the UG and ANSYS Workbench co-simulation for multi-objective optimization. Finally, comparing the simulation results ＂after optimization with the results before simulation, it could provide theoretical basis for structural design and optimization of house- hold safe house.
