摘要
平盖是化工设备设计中常用的一种结构型式,平盖一般与筒体焊接或通过法兰螺栓连接。除压力容器设计标准GB150-2011中的平盖仅仅考虑承受压力的工况外,着重分析承受外压的平盖另加集中载荷的二种连接工况,对这种双重工况的平盖进行受力分析,提出平盖厚度和平盖应力的工程设计的计算方法。
Flat is one of the commonly used structures in process equipment design, which is generally connected with cylinder by welding or bolted flange. In the standard GB150, only the fiat subjected to pressure is involved. In this article, the flat subjected to both external pressure and concentrated load was analyzed. With the stress analysis for the fiat under this kind of condition, the calculation methods of thickness and stresses for the fiat were presented.
