Anyone seeking to control the risks from vibration transmitted to the hands and arms may contemplate the use of anti-vibration gloves. To make an informed decision about any type of personal protective equipment, it is necessary to have performance data that allow the degree of protection to be estimated. The information provided with an anti-vibration glove may not be easy to understand withou...

Continuously monitoring the operation of each individual fan can significantly improve the measurement quality of aerial pollutant emissions from animal buildings that have a large number of fans. To monitor the fan operation by detecting the fan vibration is a relatively new technique. A low-cost electronic vibration sensor was developed and commercialized. However, its large scale application...

BACKGROUND Tissue healing is an intricate process that is regulated by circulation. Heat modalities have been shown to improve skin circulation. Recent research supports that passive vibration increases circulation without risk of burns. Study purpose is to compare and determine effects of short duration vibration, moist heat, and a combination of the two on skin blood flow (SBF) and skin tempe...

Stewart platform is a good candidate for high speed and six degree of freedom motion control, finding its application in the area of multi-axis vibration control. The critical problems associated with Stewart platform are the high non-linearity and uncertainty in its dynamics. To model the system dynamics of the Stewart platform a simple linear model is developed, for the motion of the Stewart ...

Regular whole body vibration training, i.e. standing on a platform that vibrates at a high frequency over a small amplitude, has been reported to produce neuromuscular adaptation and increase bone mineral density in some frailer populations [1]. As such, it has attracted interest for its potential benefits regarding physical function, fall and fracture risk in older people. These potential bene...

OBJECTIVES To investigate changes in digital circulation during and after exposure to hand transmitted vibration. By studying two frequencies and two magnitudes of vibration, to investigate the extent to which haemodynamic changes depend on the vibration frequency, the vibration acceleration, and the vibration velocity. METHODS Finger skin temperature (FST), finger blood flow (FBF), and finge...

Many advanced techniques have been developed for vibration-based machine fault diagnosis. One of the prerequisites to use vibration for fault diagnosis is the vibration signal measured from a machine component must be well isolated from other vibrations that are generated by adjacent components. Many machines have numerous and small components that are closely packed together. Due to limited sp...

BACKGROUND Circulation plays an essential role in tissue healing. Moist heat and warm water immersion have been shown to increase skin circulation; however, these heating modalities can cause burns. Recent research has shown that passive vibration can also increase circulation but without the risk of burns. MATERIAL/METHODS The aim of this study is to compare the effects of short-duration vib...

natural vibration analysis of plates represents an important issue in engineering applications. in this paper, a new and simplify method for vibration analysis of circular and rectangular plates is presented. the design of an effective robust controller, which consistently attenuates transverse vibration of the plate caused by an external disturbance force, is given. the dynamics of the plate i...
