摘要
文中提出了一种新型消振元件──可用于消除变频振动的液压式固有频率可控动力消振器。介绍了该消振器的原理、动态特性、动刚度的计算和实验曲线以及固有频率和油区的关系曲线。进行了手控变频消振实验。结果表明，该消振器对于变频振动具有令人满意的消振效果。
This paper studies a new kind of vibration damping element-the hydraulic natural frequency controllable dynamic vibration absorber,whichcan be used in the damping of fundamental frequency of vibrations with constant or variable frequency. The principle of the absorber is described, and its dynamic characteristic is analyzed. The calculation and experimental results of its dynamic stiffness are shown for comparison purpose,damping experiments were carried out for vibration with changing frequency and the results are satisfactory.
