The assembly is equipped with one imbalanced-weight gyratory motor that creates multi-plane inertial vibration for the purpose of controlling the ...

Revisiting the models of vibration screening process | JVE ...

Vibration screening is a process of great significance for granular materials processing. Notwithstanding the fact that the process has been studied with careful attention [1-4], its theory is by no means complete yet. Particularly, the relative role of stochastic and deterministic processes has not been clarified so far.

Environmental stress screening - Wikipedia

Environmental stress screening (ESS) refers to the process of exposing a newly manufactured or repaired product or component (typically electronic) to stresses such as thermal cycling and vibration in order to force latent defects to manifest themselves by permanent or catastrophic failure during the screening process. The surviving population, upon completion of screening, can be assumed to ...
