vibration Test Fixtures
Vibration Test Fixtures
Vibration testing and shock testing are part of many test programs, and there are a wide variety of vibration types, but the one thing every test has in common is that the equipment under test must be mounted with specialist vibration testing fixtures to interface between the vibration table and the product. These fixtures have to be custom designed to meet the holding points on the payload and the fixing points on the vibration system and must not compromise the results of the tests.
CentraTEQ offers design and manufacture of test fixtures for both new customers and users of vibration tables from any manufacturer.
Benefits
- Enables reliable connection to your vibration test system.
- Can very precisely simulate product under test real life mounting geometry for more accurate test simulation.
- Can allow multiple products to be tested at the same time.
- Allows testing of multiple products in different axis at the same time.
- Various materials of manufacture depending on test environment, mass requirements, etc.
- Can be designed with a common base platform initially allowing simpler adaptors to be used as product develops and changes.
- Fixture designs optimised to ensure no unwanted resonances caused by poor jig design are applied to your product under test.
Without well designed and precisely fabricated fixturing, the coupling between the test item and vibration system is usually compromised and can result in under-test or over-test of the product. The test results may well be erratic, time will be spent troubleshooting, and ultimately a fix will need to be implemented that should have been included in the original design.
From concept to manufacture CentraTEQ provides a complete turnkey solution to your vibration fixture requirements helping to guarantee the integrity of your tests.

2. Details of which Vibration System you are using
3. Your test profile
Vibration Test Head Expanders
We offer Head Expanders for applications where a larger test mounting surface is required. Head Expanders are manufactured from light-weight magnesium alloys, providing high strength to weight ratio. A choice of less expensive aluminium alloys is also available for smaller fixtures without much addition to the total mass.
A Head Expander allows multiple items to be tested simultaneously, decreasing total test cycle time. Head Expanders with load support guidance allow payloads with large footprints to be safely mounted and tested on the shaker, reducing the risk of damage to the shaker suspension system.
Guided Head Expanders are designed for testing of large, heavy packages to handle tough transportation and other demanding test profiles while providing additional restraints and load support.
Benefits
- Uniform surface obtained by precision machining
- Magnesium composition fixture for lower total operating mass
- Round, square and octagon shape Head Expander are available
- Frequency up to 2,000Hz
- Designed to couple with your current shaker system
- Easy integration with thermal chamber and with optional thermal barrier
- Cost effective – increased testing yield
- High resonant frequencies available, depending on size
- Choice of insert mounting hole pattern available
- Special surface processing by coating with protect layer
