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, ...

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 ...

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 ...

Jet engine vibration is arguably the worst enemy of a typical aircraft maintenance team. Parts which are out of balance can eventually result in a cracked turbine, fan, and compressor components, as ...

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 ...
