现场制作给水箱的静力分析

Static Analysis of Water Tank Built on the Spot

对矩形给水箱中的成品给水箱和现场制作水箱进行了比较,现有的现场制作给水箱是直接仿照不锈钢的成品给水箱,可能存在安全隐患的问题。根据不锈钢的成品给水箱的内部拉筋形式设计现场制作水箱,对其进行三维建模,建立有限元模型,并进行静力分析。研究发现水箱四面立板中心部位变形较大,且立板连接处应力较大,有开裂的隐患,需要在设计和加工现场制作水箱时添加一圈加强筋,以增强水箱的强度刚度及安全性。

As rectangular water tank,the finished product water tank is compared with the water tank build on the spot.The on-site production of feed water tank is a direct imitation of the stainless steel finished product feed water tank which may have hidden safety problems.According to the internal strengthening rib form of the stainless steel finished product feed water tank,the design of on-site production of water tank will be obtained.Then,the three-dimensional modeling,the es-tablishment of finite element model,and static analysis are carried out using the ANSYS software.The study found that the central part of the vertical plates on all sides of the water tank is deformed greatly,and the stress at the connection of the vertical plate is large,so that there is a hidden danger of cracking.It is necessary to add a ring of reinforcing bars in the design and manufacture of the water tank built on the spot in order to enhance the strength,stiffness and safety of the water tank.
