摘　　要：以大型电站排汽装置为研究对象,建立三维壳体模型,运用有限元分析理论,对设计条件下的排汽装置的强度及稳定性进行了分析,并根据计算所得位移载荷曲线得出设备临界载荷,判断设备稳定性,根据设备应力分布,判断设备强度。Taking the large-scale power plant exhaust device as the research object and establish a three-dimensional shell model.The strength and stability of the exhaust device under design conditions were analyzed by using the finite element analysis theory.According to the calculated displacement-load curve,the critical load of the device is obtained,and the stability of the device is judged.According to the stress distribution of the equipment,the strength of the equipment is judged.
