摘　　要：为讨论实肋板式耐压液舱结构中的应力分布和各种加强形式对液舱区结构应力的影响,利用ANSYS软件对相同尺寸的不同耐压液舱结构形式分别进行了有限元计算,通过对比得出:在船体壳板、液舱壳板加纵骨和在液舱壳板上加设中间支骨分别对降低耐压船体中的应力特别是轴向应力、液舱壳板的轴向应力以及周向应力效果十分显著.In order to discuss the stress distribution of solid frame pressure tank structure and the stress effect of different stiffened types, finite element stress analysis of different pressure tank structures of same size were made by ANSYS. Based on these calculations, it was found that the stress, especially axial stress of hull plate, axial and radial stresses of tank shell could be reduced greatly if stringers and ring-frames were added to hull plate and hull shell respectively.
