Vibration, Mechanical Shock, and Impact
Time-varying forces and accelerations occur in daily life, and are commonly experienced, for example, in an elevator and in aircraft, railway trains, and automobiles. All of these situations involve motion of the whole body transmitted through a seat, or from the floor in the case of a standing person, where the human response is commonly related to the relative motion of body parts, organs, an...
متن کاملMechanical Bed for Investigating Sleep-Inducing Vibration
In running cars or trains, passengers often feel sleepy. Our study focuses on this physiological phenomenon. If a machine can reproduce this phenomenon, it is feasible to put a person, such as an insomnia patient or an infant, to sleep without any harmful effects. The results of our previous study suggest that low-frequency vibration induces sleep. This report describes a new mechanical bed for...
متن کاملOccupational exposure to mechanical vibration: the Italian vibration database for risk assessment.
The Italian vibration database is presented. It is hosted by a web server at the National Institute of Occupational Prevention and Safety (ISPESL) in Rome, Italy (http: / /www.ispesl.it/vibrationdatabase). It supports in risk assessment employers who have to comply with Legislative Decree 187/05, now replaced by Legislative Decree 81/08, which transposes into law Vibration Directive 2002/44/EC....
متن کاملVibration Analysis of Global Near-regular Mechanical Systems
Some near-regular mechanical systems involve global deviations from their corresponding regular system. Despite extensive research on vibration analysis (eigensolution) of regular and local near-regular mechanical systems, the literature on vibration analysis of global near-regular mechanical systems is scant. In this paper, a method for vibration analysis of such systems was developed using Kr...
متن کاملStochastic resonance in a nonlinear mechanical vibration isolation system
This paper concerns the effect that a stochastic resonance can have on a vibration isolation system. Rather than reducing the transmitted force, it is shown that it is possible to significantly mask the component of the force transmitted though the isolator, when the system is excited harmonically. This can be achieved by adding a very low intensity of random noise to the harmonic excitation fo...
