摘要

在地震载荷条件下,使用ANSYS8.0软件分析了1000m3球罐的拉杆直径变化对球罐应力的影响。分析结果表明,球罐的最大应力点位于球罐与盖板连接处外壁面的上侧,拉杆直径的变化对球罐与盖板连接处的应力影响较大,对其他部位的应力影响相对较小,在选择球罐的拉杆直径时应充分考虑拉杆对球罐应力的影响。
ANSYS 8.0 software was used to analyze the influence of the diameter change of the tie-rods of a 1 000m3 spherical tank on its stress.The analysis result shows that the maximum stress point of the spherical tank is located at the up side of the external wall of the connection of the spherical tank and the cover plate,the diameter change of the tie-rods has a large influence on the stress of the connection of the spherical tank and the cover plate,and has a little influence on the other locations.The influence of the tie-rods on the stress of the spherical tank should be fully considered when selecting the diameter of tie-rods.
