摘　　要：为研究内置式环形耐压液舱在液舱周向范围变化时的力学规律,采用ANSYS有限元法对单壳体内置式耐压液舱进行了强度计算,对液舱与外界是否连通两种载荷工况下的应力情况进了比较分析。结果表明:在两种载荷工况下,液舱周向范围的变化对液舱应力变化的影响规律相同,但液舱内外相连通时的应力值更高;液舱周向范围280°左右时对结构的变形最为有利。In order to research the mechanics law of inner annular pressure tank with the change in its circumferential range,a strength compilation method of mono-shell inner pressure tank is carried out based on finite element.The stress situations under two kinds of payloads conditions in the tank are compared and analyzed.The result shows that under the two different conditions,the change of tank circumferential range has the same effect on the change of tank shell stress according to the rule.The stress′value is greater when the liquid is connected to the outside.It is most favorable for the structure′s deformation when the range is about 280°.
