磁流变阻尼器对齿轮系统减振降噪实验研究
Experimentally Reducing Vibration and Noise of Gear System using Magneto-rheological Damper
摘要
Abstract
In order to solve the problem that the gearbox of a gear system causes too large vibration and noise during operation,a magneto-rheological damper for suppressing its vibration and noise was proposed.A gear vibration and noise reduction bench was built to experimentally evaluate the damping characteristics of the magneto-rheological damper by monitoring the vibration of the bearing block,rotor and sound pressure level of the gear system.The evaluation results show that the damper can effectively reduce the gear system's vibration and noise.The root mean squares (RMS) values of the vibration acceleration and velocity of the bearing block are reduced by 50％.The peak-to-peak value of rotor vibration is reduced by 55％.The sound pressure level is reduced by 8 dB.The damper can simultaneously inhibit each frequency component of the gear system's vibration and noise in a wide frequency range.The experiments performed in the paper verify that the damper can effectively guarantee the smooth operation of the gear transmission system with good vibration reduction characteristics over a range of operating speeds.关键词
