After getting some mini massagers for the fair sex from a discount sale fair, I started thinking about vibration/haptic motor projects again! I’m in the middle of a lot of projects based on small ...

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 ...

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 ...
