Vibration Testing
LabTest Certification Inc. offers vibration testing using our three-axis Electrodynamic Shaker System . This system offers a high force and displacement rating, which allows us to test according to the most stringent vibration profiles.
Vibration testing is the process of applying a pre-defined amount of vibration to a test specimen by controlling the parameters including frequency, acceleration, displacement and duration. Equipment can be subjected to vibration testing for many purposes including establishing reliability, detecting resonances or demonstrating compliance with a standard. At LabTest, the test article is securely mounted on our electrodynamic shaker table and vibration is applied at the levels required to meet your needs.
LabTest Certification is an accredited ISO 17025 Testing Laboratory for Shock & Vibration testing for a large variety of products in the areas of Military, Marine, Avionics, Automotive, and more.
Vibration and Shock capabilities are as follows
Sine/Random/Sine-on-Random/Random-on-Random Vibration testing and other vibration profiles, upon request:
DC–3 to 4000Hz frequency range
60,000 N force rating
Maximum static load/payload 2000lbs
4 to 8 channel data logging; with our Spider 81 (Crystal Instruments) Vibration Controller System; 1 reference channel and up to 7 monitoring accelerometer channels
Arrangements can be made to increase the number of monitor accelerometers and data logging channels upon request
Classical Shock Testing:

Pre/Post shock profile compensation
4 to 8 channel data logging; with our Spider 81 (Crystal Instruments) Vibration Controller System; 1 reference channel and up to 7 monitoring accelerometer channels
Arrangements can be made to increase the number of monitor accelerometers and data logging channels upon request
Temperature-Conditioned Vibration:
All vibration and shock tests can also be performed at high and low temperatures by utilizing a thermal chamber specifically designed to fit over our shaker system. The thermal vibration chamber is capable of temperatures from -50°C to +85°C and can achieve very high rates of thermal change
Vibration testing can provide a range of useful information from the early research and development stage of a product through to the final design verification and/ or certification stages. Some of the useful benefits of performing vibration testing include:
- Demonstrate that a product complies with the criteria of various test specifications
- Identify resonant frequencies
- Verify that a product can physically withstand the expected vibration exposure of its life cycle.
- Verify that a product can operate throughout the expected vibration exposure of its life cycle
- Locate ‘weak links’ in the design during the development stage to identify where the most effective improvements can be made
- Generate maintenance schedules with confidence
- Sine Sweep/Resonance Search, Track and Dwell (RSTD).
- Shock Response Spectra (SRS).
- Multi-Sine and Sine Oscillator.
- Transient Time History (TTH) and Transient Random Control.
- Earthquake Control
- Time Waveform Replication.
- Transportation Simulation.
- Military Equipment Testing.
- Vehicle Component Testing.
- Aircraft Component Testing.
- Marine Component Testing.
- Li-Ion Battery Transport Testing.
- Vibration Sensor Verification.
- Combined Vibration/ Temperature Testing
