摘　　要：针对人们在高原地区工作时易产生高原反应的问题,设计一种高原恒压营房,并通过有限元仿真分析真实工况下的结构响应,基于响应特征及使用要求对结构进行优化,提出加设斜梁结构或更换管材并调整梁结构跨距两种改进方案,进而分析改进后的结构稳定性。结果表明:加斜梁的钢架结构使得整体最大变形量降低了24.8%,但整体变形量仍较大,无法满足使用要求;更换管材和调整跨距的优化方案使得底板最大变形量降低了79.4%,大大增强了稳定性,同时该方案可以控制结构的最大应力在钢材的许用应力范围内,增加材料的使用寿命,优化后的营房整体质量增加6.67%。Aiming at the problem that people are prone to altitude sickness when working in the plateau area,a kind of constant pressure barracks was designed,and the structural response under real working conditions was analyzed by finite element simulation.Based on the response characteristics and application requirements,the structure was optimized,and two improvement schemes of adding inclined beam structure or replacing pipes and adjusting the span of beam structure were proposed to analyze the stability of the improved structure.The results showed that the steel frame structure with inclined beam reduced the overall maximum deformation by 24.8%,but the overall deformation was still large,which can not meet the requirements of use.The optimized scheme of replacing pipes and adjusting spans reduced the maximum deformation of the bottom plate by 79.4%,greatly enhancing the stability.At the same time,the scheme could control the maximum stress of the structure within the allowable stress range of the steel,increased the service life of the material,and increased the overall quality of the optimized barracks by 6.67%.
