【摘要】 针对液化乙烯气船舶C型独立液货舱在内部真空载荷作用下失稳而损坏的问题,计算该液货舱模型的临界压力和许用轴向应力,运用有限元方法得到该实际货舱壁在不同真空状态下的最大轴向应力变化规律,确定液货舱工作中的最大允许真空度,指出避免货舱失稳的相关措施。更多还原

【Abstract】 The C-type tank of LEG carrier may lose stability and be damaged under the vacuum situation.This paper calculates the critical pressure of the tank and analyzes the variety pattern of the maximum axial stress in the bulkhead under different vacuum by finite element method.The maximum allowable vacuum for this separated C-type tank is determined and the corresponding measures to prevent structure from buckling are discussed.更多还原
