The car is placed as a whole in the warehouse and exposed to negative pressure environment, which can realistically restore the low-pressure working state. The characteristic is high cost and the need to build an altitude warehouse steel shell.


Structure of EST altitude warehouse:

The outer compartment is made of airtight steel shell, ensuring the airtightness and internal pressure of the compartment.

The inner compartment is made of polyurethane insulation board to ensure the temperature and humidity of the sample.

Size of EST altitude warehouse:

Internal usage space: 24m x 6m x 6m (L x W x H)

Altitude experiment altitude: 0-5500m altitude

Vehicle entrance size: 4.5m × 5.0m (W × H)

Personnel transition room: 2m × 2m ×  2.5m (L x W x H)

Personnel door size: 1m x 2m (W x H) with two single leaf opening doors

The floor of the test vehicle carrying the load at the bottom of the warehouse body

Design process:

Selection of main materials for the warehouse body;

Preliminary scheme design;

Perform finite element analysis:

Perform finite element analysis on solid modeling;

Feedback from finite element analysis to optimize and improve the design

This process loops until the final design drawings meet the requirements.
