A Portable Non-Contact Tremor Vibration Measurement and Classification Apparatus

Measurement of hand-vibration transmissibility by non-contact measurement techniques

Background: Workers who use hand-held vibrating tools may experience finger blanching attacks due to episodic vasospasm in the digital vessels. In occupational medicine, the pathological consequences to the exposure to handtransmitted vibration are known as vibration induced white finger (VWF). In many cases, workers are recommended to use anti-vibration gloves and a standard procedure (ISO 108...

Vibration isolators for portable vibrating tools. Part 6. Problems concerning vibration force measurement.

Multi-point independent simultaneous force measurements were made to investigate the vibration force distribution on the palm and to determine one representative point on it for the purpose of field survey. The phase relationships between the force and the acceleration were also pursued. In connection with vibration force transmission, important effects such as vector, bypassing and mechanical ...

Design of a non-contact magnetic spring for vibration isolation

This document serves to summarise the research performed by the author undertaken in approximately the first six months of his doctorate. The aim of the project is to build a vibration isolation table using non-contact magnetic springs. The document is structured with an introduction to the project, followed by an introduction to the field of magnetic levitation, including a literature review. ...

A Fiber Optical Sensor For Non–Contact Vibration Measurements

Vibration tests are widely employed in many industrial fields, and in particular in aerospace industry to evaluate the mechanical behavior of parts for aircrafts and satellites. Usually, these tests are carried out with shakers, while inertial accelerometers are used to measure the shaker table acceleration from which the vibration amplitude is computed. Some applications require the measuremen...
