System Introduction
（1） Supporting vibration system: (to be provided by the user)
1. Equipment introduction (relevant parameters are provided by the user's device and measured on site)
An electric vibration testing system with a table size not exceeding 1200 * 1200mm can be selected, which is widely used in aviation, aerospace, weapons, ships, communications, automobiles, electronics, electricians, home appliances and other fields. We can provide comprehensive testing equipment for multiple environments such as climate and mechanics.
The vibration testing system is mainly used for conducting vibration and impact environment tests, environmental stress screening tests, reliability tests, and fatigue tests on products to assess their lifespan.
(The main technical specifications of the corresponding model of equipment system provided by the supporting manufacturer)
（2） Temperature test chamber system:
1. Main technical indicators

Temperature fluctuation: ± 0.3 ℃ (at constant temperature)
Temperature uniformity: ≤± 1 ℃ (0-70 ℃): ≤± 2 ℃ (1-150 ℃) measured under no-load conditions
Humidity range: 20% to 98% RH (meeting the requirement of simultaneous temperature and humidity alternation)
Humidity fluctuation: ± 2.5% RH
Heating rate: 1-3 ℃/min (average without load)
Cooling rate: 1-1.5 ℃/min (average unloaded)
Balance method: adopting cold balance
Connection table size: 1200 * 1200mm, (horizontal+vertical)
Connection plate: horizontal+vertical+blind plate (docking table surface is 1200 * 1200mm, docking 5-ton vibration table)
Water supply system: Central purified water supply system, automatic replenishment method (provided by the equipment manufacturer of the central water supply system)
Water flow rate: flow rate 10M3/h (centralized cooling tower water supply, equipment and pipeline construction provided by equipment manufacturer, silent cooling tower, noise: ≤ 65Db, circulating water pump one backup and one in use)
Observation window: multi-layer hollow anti fog glass, size ≥ 400 * 500mm
Communication control: remote RS232, RS485 communication
Panel over temperature: The panel has independent over temperature protection, and the temperature can be set independently to prevent the instrument from losing control and causing danger
Test lead hole: one φ 100mm test hole on the left and right sides of the box, and equipped with special foam rubber plug.
Fault alarm: protection against water shortage, overcurrent, dry burning, overheating, high pressure, etc
Power: 40KW
Operating power: 30KW
2. Box structure
The test box adopts an integral structural form, with internal channel steel reinforcement to ensure that the strength of the box remains unchanged. The box studio adopts a whole welding process and is sealed with high and low temperature resistant organic silicone material. The company completes the assembly and ships the whole.
Lifting system: The bottom is equipped with a hydraulic lifting system+motor-driven left and right movement, with left and right directional movement tracks,
And provide limited protection to prevent the device from moving within its effective range. The elevator is equipped with a mechanical locking device to prevent it from descending from a high position for a long time, compressing the vibration table and causing losses.
Shell material: The surface of the galvanized sheet is treated with acid pickling and phosphating before electrostatic spraying.
Internal material: General SUS304 # (thickness 1.2mm) stainless steel plate with integral welding and internal reinforcement structural components
Pressure balancing device and exhaust port: A pressure balancing device is installed at the top of the studio to balance indoor pressure fluctuations.
Bottom drainage: There is a condensate drainage outlet at the bottom to facilitate the timely discharge of condensate or leaked liquids.
Observation window: multi-layer hollow anti fog glass, size ≥ 400 * 500mm
3. Test box blind (bottom) plate
The test chamber is equipped with three blind plates, one is a movable bottom (blind) plate used for high and low temperature tests, one is a movable bottom plate connected to the vertical vibration table for temperature and humidity (vertical) vibration comprehensive tests, and one is a movable bottom plate connected to the horizontal vibration table for temperature and humidity (horizontal) vibration comprehensive tests.
4. Connection between the box and the vibration table
During horizontal vibration, it is directly connected to the horizontal sliding table. For comprehensive testing of vertical vibration, an expansion table must be installed. The equipped test box base is mainly used for testing at three workstations: horizontal vibration, vertical vibration, and no vibration; The sealing material between the vibration table and the test chamber is made of silicone tape with good high and low temperature resistance
5. Box lifting and track transmission device
In order to ensure the interface between the test chamber and the vibration table has good mechanical transmission characteristics while maintaining thermal and air tightness. Equipped with a hydraulic vertical lifting system to ensure that the box can move up and down. The bottom of the box is equipped with track rollers that can slide back and forth on the track, making it easy to separate the box from the vibration table. When in use, use the specially designed high and low temperature resistant silicone rubber pad provided by our company for moisture insulation, waterproofing, and sealing to connect and seal.
