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.
Here is what you need to do before going ahead with Vibration Testing
Vibration and Shock capabilities are as follows:
- Sine/Random/Sine-on-Random/Random-on-Random Vibration testing:
- DC–3 to 4000Hz frequency range
- 60,000 N force rating
- Maximum static load/payload 2000 lbs
- 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 accelerometer channels upon request
- Classical Shock Testing:
- Half-Sine/Terminal or Initial Peak Sawtooth/Triangle/Trapezoidal pulse shapes
- 120,000 N (newton) shock force rating
- Maximum static load/payload 2000 lbs
- 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 accelerometer 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 -40°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
