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 ...

Vibration motors are the silent workhorses behind tactile feedback in wearables and handheld devices. These compact actuators convert electrical signals into physical cues, enriching user interaction.

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 ...

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 ...

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 ...

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 ...
