Gearbox Noise and Vibration Prediction and Control
This paper will review practical techniques and procedures employed to quiet gearboxes and transmission units. The author prefers solving the gear noise problem at the very source to introduce an enclosure as a means to reduce radiated noise, which seems to be easy but its effect on the sound pressure level is small. The gearbox noise problem solution is focused on the improvement of gear desig...
متن کاملGear Noise and Vibration – a Literature Survey
This paper is a survey of the literature on gear noise and vibration. It is divided into three parts, “Transmission error”, “Dynamic models” and “Noise and vibration measurement”. Transmission error (TE) is considered to be an important excitation mechanism for gear noise and vibration. The definition of transmission error is “The difference between the actual position of the output gear and th...
متن کاملRail System Noise and Vibration Control
Control of noise and vibration emitted by steel wheel and rail transportation systems has a long history of designs and techniques, some of which were dismal failures and some which worked very well. Many of the early efforts had a valid technical base for the design, however, there were also many based on intuition or ideas with great expectations, but which had no real technical basis. In the...

متن کاملThe Effects of Noise and Whole Body Vibration on Urinary Metanephrine and Normetanephrine
Background and Aim: Little attention has been paid to the effects of combined exposure to noise and vibration. Exposure to noise and vibration can effect stress hormones and may lead to high blood pressure and cardiovascular disorders. This study aims to investigate the effects of noise and vibration on urinary Metanephrine and Normetanephrine among men. Methods: In this experimental study, 30 ...
