Most vibration in the real world is random. For example, a vehicle traveling over roads experiences random vibration from the road's irregularities. A ground-launched rocket experiences non-stationary vibration during its flight - the motor ignites, the rocket travels through the atmosphere, the motor burn ends, and so forth. Even a wing, when subjected to turbulent airflow, undergoes a random vibration response. Among the many items typically tested with random vibration are motorcycle components, jet engines, cruise missiles, catalytic converters and any products that will see transportation.
NTS is capable of generating up to 70,000 force pounds with tandem shakers and up to 45,000 force pounds on a single shaker. NTS has performed vibration testing in excess of 200 GRMS in a single band and can hook up in excess of 100 data channels. Our engineers understand proper placement of accelerometers and force limiting instrumentation. Need a high number of data channels? Our systems can accommodate 60 or more data channels and still give you the data right at the end of the test with a formal report following in less than two weeks.
NTS performs a wide variety of tests designed to evaluate equipment and materials when subjected to various types of noise/sound. Contact us today for more information about how we can assist with your specific vibration testing requirements.
