Vibration tester for material samples and components - has damped piston supports and eccentric oscillation drive system induced by motor

摘要

A device for vibration testing samples of material has a base with two fixings for the sample and a device which applies vibrations to the sample. It is designed to enable pure flexural oscillations to be applied not only to samples but also to finished components. Each suspension fixing consists of a piston rod (9) with a link (10), a piston (7) attached to its lower end, a cylinder (6) and a clamp (4) for gripping the sample (1) attached via a universal joint (5). The piston has a spring damper (8) concentric with the rod (9). Oscillations are induced by a motor (22) via an elastic shaft (23) and an eccentric wt. (24).
