VIBRATION TEST CHAMBER

Vibration Combined Temperature Humidity Test Chamber / Climatic Test Chamber with Vibration Shaker / Composite Temperature Humidity Vibration Battery Testing Chamber Manufacturer

THE ULTIMATE SOLUTION FOR VIBRATION CLIMATE TESTING (Vibration Climatic Test chambers)

A product is exposed to various mechanical loads during its life cycle. This exposure can occur both during transport and in normal operation. To ensure that the product is capable of supporting these loads, they are simulated in the laboratory with vibration tests. Electrodynamic shakers are implemented to excite vibrations in the component for vibration analysis and modal analysis. These agitators are also used for in-service life tests, in which high
frequencies are applied.

Vibration Climatic Test chambers that can be interfaced with various types of vertical, horizontal shaker. Lifting system through worm with activation via touch screen panel or remotely. Different floors for each type of shaker. With sizes of several liters (other sizes on request), temperature ranges ranging from -99⁰C to + 200⁰C, humidity between 10% and 98% and temperature variation rates of 5, 10 or 15⁰C / minute. Wide range of accessories and
options. Remote monitoring system.

Working Principle : Vibration Combined Temperature Humidity Test Chamber has high and low ramp rate in terms of temperature and humidity with vibration environment. These chambers are designed for high/low relative humidity & high/low temperature range compatible with the mechanical and electrodynamic vibrations system. The Vibration table are designed for the testing of vibrations of very small electronic components and Environmental test chambers  gives a combined testing of temperature, humidity and vibration testing in one equipment.

MIL-STD-202 – Vibration Testing Methods: Two types of vibration testing methods that works on high and low frequency.

Method 201 – Vibration, High Frequency:

• Purpose:  It is used for the calculation of components withstand at high frequency vibration on vibration shaker.
• Frequency Range: 10 Hz to 2000 Hz
• Acceleration Levels: Up to 20 G
• Test Duration: 4 hours per axis (12 hours total)
• Waveform: Sinusoidal
• Sweep Rate: 1 octave per minute

Method 204 – Vibration, Sweep:

• Purpose: It tests the ability of a component to withstand vibration over a range of frequencies on vibration shaker.
• Frequency Range: 10 Hz to 2000 Hz
• Acceleration Levels: Up to 20 G
• Test Duration: 12 hours total (4 hours per axis)
• Waveform: Sinusoidal
• Sweep Rate: 1 octave per minute, with a minimum of 4 complete cycles

TEMPERATURE AND VERTICAL VIBRATION CLIMATIC TEST CHAMBER

1. Advanced chambers for vibration and temperature testing or advanced chambers for vibration and temperature testing on feet are widely approved by users.
2. With volumes from several L to several m3.
3. Temperature range from -99 ° C to 200 ° C and more range.
4. It is built to be placed according to the shaker used by the user.
5. Multivalence and test modes (hot, cold, hot-cold-humidity).
6. Uniformity with the entire line of CLIMATS environmental chambers.
7. These chambers, built to user specification, are dedicated to combined tests of vibration, temperature and humidity.
8. The test volumes are optimized according to the geometry, nature, mass and dissipation of the product to be tested, while using a vibrating element.
9. These environmental chambers are modifications of the standard chambers.
10. They benefit from the CLIMATS experience, which includes ventilation, a refrigeration machine, an electric plate, control software, which are the basics of our buildings.
11. The flexibility of the manufacturing process allows the construction of environmental chambers: with the test volume rising forward with a vibrating jar or a movable plate, it can slip under the chamber; chamber lifted by the feet with the camera being simply positioned on top of the shaker.
12. A perfect seal is guaranteed between the shaker and the chamber.
13. An additional plate allows the camera to be used in conventional mode as well.
14. The vibration frequency shall be varied logarithmically between the approximate limits of 10 and 2,000 Hz.  However, the procedure of method 201 may be applied during the 10-55 Hz band of the vibration frequency range.

VIBRATION TEST CHAMBER CHARACTERISTICS

Very Easy Operation

 A worm-type lifting system, managed by a touch screen control panel, allows the test cabin to be adapted to any height of the shaker.
 It is also possible to add horizontal movement on request. This is especially valuable if the shaker allows both vertical and horizontal movement or if more than one shaker is needed in the same chamber.

Great Flexibility

 Different backgrounds, for vertical and horizontal vibrations, can be adapted for any existing shakers.
 If there is a need to use the camera without the shaker in place a blind bottom is available.
 The test cabin is managed by a detachable control panel on the right side of the chamber.

Standard Models

 Available sizes several liters; the temperature range is -99 to 200 ° C, while the humidity range is 10% to 95% (in the + 10 / + 95 ° C temperature range).
 3 temperature variation are available: 5, 10, or 15 ° C / minute.
