The vibration signature of a motor can tell you a lot about what’s going on. Entry level vibration testers can tell you the magnitude. If you have the training, you can use more sophisticated testers ...

The principal vibration testing capabilities which are in common use today largely evolved from the early requirements of the aerospace industry. Standard test protocols, random vibration, single axis ...

This article was updated May 24, 2023. It was originally published Oct. 10, 2000. Noise and vibrations in power transmission devices—both those that use linear, reciprocating motion and rotational ...

A testing machine can be used to push, pull or twist a sample of the material in order to determine the mechanical properties of a material. Many materials are strain rate sensitive which means that ...

Single-shaker vibration test systems have been used for many years to explore a test item’s resonances. Swept sine testing applies only one frequency at a time so resonances are excited separately. In ...

Industries and R&D sites depend on sensors to measure, monitor and analyze vibrations. Unfortunately, the best ways to get accurate and repeatable vibration data are not clear to many engineers; they ...

Excess vibration destroys bearings, windings, and even the cases of motors. Not only that, the vibration can travel through the pipes, couplings, and other parts of the system to damage gearboxes, ...
