Abstract This paper designed a simulation test platform of 4000-m deep sea hydrostatic pressure environment , the platform component are: a container cylinder, a end-cover which is located in a container at the top of the cylinder, a sealing flange, a few auxiliary components and control systems。 open a observation hole at the bottom of the cyliner container, to  real-timely

monitor the experiment，high-speed cameras is installed after subassemblies is installed first;

opened a water injection hole on the end-cover ,inject the water into injection container cylinders to pressure change, it's include of a light source hole component, a pressure sensor and a pressure needle valve on the end-cover, the pressure sensor monitor the  internal pressure momentarily, transfer data to the control circuit, mentaining a fixed  pressure, pressure needle valve is used to rule out the air in the cylinder before the experiment and unloading pressure in the cylinder; Cylinder through the end cover on the mobile device on the drive end cover to move up and down, the end cover flange and cylinder container top of extension flange, using concave type card slot accurately on the end cover lock cylinder on the container, the seal card slot respectively by two cylinder to control its lock tight or loose; Seal card slot used for locking, double seal design for hermetically sealed。

According to the known technical indicators, based on JB4732-1995  "Steel  pressure vessel - Analysis and design standards", the size of model is finally decided after structure project design, material selection, structure design and related verify,then set up the 3D model, draw the 2D drawings, and complete the loop design refered to " Hydraulic pneumatic system

design manual"。 When it's cylinder，the end-cover on the container，the shape change   and

strength of the high pressure tank are analyzed according to the ANSYS software, the internal volume change of hyperbaric chamber is discussed, the relevant conclusions finally is got to verify the safety of hyperbaric chamber。

Key words: hydrostatic pressure; High pressure tank; Control; The finite element Analysis
