摘要

摘要: 针对齿轮箱在运行中振动噪声较大的问题，提出一种将磁流变阻尼器用于齿轮传动系统的振动噪声控制的方法。搭建了齿轮减振降噪实验台，通过对轴承座和转轴的振动、以及齿轮噪声声压级的监测，实验研究了磁流变阻尼器对齿轮系统的减振降噪特性。结果表明，磁流变阻尼器能有效抑制齿轮传动系统的振动与噪声，轴承座振动加速度有效值及振动烈度的幅值降幅在50%左右，转轴轴振峰峰值降幅达55%；各频率的噪声声压级均有8 dB左右的降低。阻尼器能抑制啮合频率及其高次谐波、转频及其高次谐波等各频率下的振动噪声，实现宽频减振；且能有效保证齿轮传动系统在较宽的转速范围内平稳运行。

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.
