摘要
随着我国航空航天事业的飞速发展,地面试验模拟设备的规模随之大幅增加,致使高超声速模拟设备的主要部件真空球罐不断向大型化方向发展,真空球罐大型化可以降低单位容积存储能力的投资,节约土地,节省辅助设施的费用。大型球罐建造过程中因无法进行焊后整体热处理,一般从设计上控制球罐壳体壁厚不超过38 mm,结构上采用内加T型筋形式增加球壳的强度、刚度及稳定性。本文介绍了基于20000m^(3)内加筋真空球罐的内部T型筋的加工、加强筋与球罐壳板的焊接、球罐的现场组装等多个关键技术难点,保证了大型真空球罐球罐壳板的成型及组装过程中的尺寸满足要求。
With the rapid development of aerospace industry in our country,the scale of the ground test simulation equipment increases sharply,causing vacuum spherical tank,as the major equipment in the hypersonic simulation unit,continuously become larger.Large-scale of vacuum spherical tank can reduce the investment for unit volume of storage capacity,and save the land and the cost of the auxiliary facilities.In construction of large spherical tanks,due to the fact that overall post-welding heat treatment is difficult to carry out,the shell thickness of the spherical tanks is generally controlled not over 38 mm.In the structure,T-type gusset for reinforcement is added to increase the strength,stiffness and stability of the spherical shells.In this paper,several key technical difficulties in the manufacture of 20000 m^(3)vacuum spherical tank were introduced,such as the processing of internal T-shaped bars,the welding of reinforcing bars and shell plate,and the field assembly of the spherical tank,all of which are the factors to ensure the forming of the shell plates in large vacuum spherical tank and the size precision of the shell plate for the assembly process.
