不同加强筋对救生舱舱体抗爆性能影响的研究

摘要

通过理论计算与数值模拟相结合的方式，对不同加强筋对救生舱舱体抗爆性能的影响进行了研究。对不同加强筋的抗拉（压）能力和抗弯曲能力进行理论计算与比较，采用ANSYS软件对不同加强筋进行数值模拟，结合形变云图与应力云图，综合分析比较不同加强筋的抗爆承压能力。结果表明，相同横截面积加强筋的抗爆承压能力大小关系为：半圆环形加强筋>空心方形加强筋>T形加强筋>I形加强筋。%Through combination of theoretical calculation and numerical simulation,it was studied that capsule hull antiknock perform-ance impact on the different reinforcement. It made theory calculation and comparison of different reinforcement tensile( pressure)abili-ty and the ability to resist bending,it made numerical simulation for different reinforcement by using ANSYS software,combined with the deformation nephogram and the stress nephogram,it made comprehensive analysis and comparison of different reinforcement antiknock bearing capacity. The results show that the same cross-sectional area reinforcement of antiknock bearing capacity size relations as fol-lows:the round ring stiffener>hollow square reinforced>T-shaped stiffener>I-shaped reinforced.
