Repetitive Shock Vibration Table

Let’s move some products

Repetitive Shock Vibration tables generate multi-axis vibration using one or more pneumatic impact hammer(s) (also known as impactors) that strike the bottom of the vibration table on which a product is attached. Thermotron’s repetitive shock vibration test systems are designed specifically for very aggressive temperature change rates and high levels of multi-axis repetitive shock vibration.

Repetitive shock shaker tables can be used as stand-alone units or combined with an AGREE or AST chamber for HALT/HASS testing. The repetitive shock vibration system incorporates many unique features designed to satisfy a wide range of vibration testing and screening applications for many industries.

The basic system utilizes Multi-Zone Control. This patented feature uniformly—and more effectively—tests products. As a result, you receive improved product reliability, reduced warranty and recall risks, as well as better-utilized company resources.

Additional Accelerometers

All Thermotron vibration test systems include accelerometers to measure the proper acceleration that products experience while under test on a vibration shaker. Typically, Thermotron repetitive shock tables include four accelerometers and electrodynamic vibration shakers include two. Users may purchase additional accelerometers to use on the vibration shakers.
Custom Colors
You are probably used to only seeing a Thermotron environmental chamber or electrodynamic shaker in just one of two colors – blue and gray. But we can in fact paint your piece of test equipment any color you like, provided you let us know which one.

Custom paint color is an available optional feature for equipment purchased from Thermotron, and the process is quite simple. During the quote process, you work with our Sales and Application Engineers and simply notify them what color you want your test equipment to be painted. We primarily work with RAL and FED-STD-595C – Color Standards, but if you provide us with a color and the standard it comes from we will work with our paint supplier to ensure that your environmental chamber or electrodynamic shaker is painted your specified color.

So, why would you want to have your climate chamber painted a different color? There are many reasons here are a few of the most common:

Branding – customers want to have their equipment painted to promote their brand, and incorporate their branding colors into items their staff and customers see every day.

Grouping – Some customers with many Thermotron chambers in their lab need them to be color coordinated by function, ability, or size.

Safety – We have also had customers request that only certain parts of the environmental chamber or electrodynamic shaker are painted. For example we had a customer paint all electrical panels bright orange to highlight potential safety hazards.

There are many unique reasons to specify a paint color on your environmental chamber or electrodynamic shaker, almost as many as there are colors. What color would you put on your test equipment?
Multi-Zone Control

Experience ultimate table uniformity with Thermotron’s patented Multi-Zone Control, the first of its kind on the market. The patented repetitive shock table can be divided into one, two, or four zones and run a test with superb uniformity, within 5% Grms of each zone. This feature makes dynamic adjustments automatically, compensating for system variability including inconsistencies in the table, impactor wear, air supply, fixtures, mounting, etc. Download the brochure.

Vibration Level Monitor & Alarm

This optional safety feature can be included with Thermotron Repetitive Shock Vibration Test Systems to safeguard the product(s) under test and/or the shaker system from an excessively high acceleration level. The Vibration Level Monitor (VLM) provides audible and visual alarm indication in the event a preset acceleration level is exceeded and will automatically stop the shaker system. This redundant safety feature is tied to a standalone accelerometer that can be attached to the shaker table, fixture or product. The VLM imparts an added level of safety to the PSD Vibration Limit Functions already built into the AST-8800 Controller software as standard.
CSA or CE Electrical Codes

For equipment going to Canada or the European Union, Thermotron can build the equipment to CSA or CE electrical codes to ensure the safety of equipment users and the facility.
Fixtures

Fixtures are often an important aspect of Environmental testing with chambers or vibration. Fixtures help avoid errors in product responses to various environmental simulations. Proper fixture design and product mounting are essential to accurate and effective testing.
Quiet Package

A quiet package is an optional feature that minimizes the noise levels coming from environmental test equipment. Depending on the equipment (electrodynamic shaker or climate chamber) and the size of the environmental test equipment, the quiet package will look and vary in functionality.
