摘要
本文发展了其固有频率可由仓内空气压力和作为动吸振器质量的水的调节来控制的动吸振装置。作者进行了模型试验，试验结果显示了流体动吸振器有如下优点：（１）吸振器频率容易改变。（２）减振效果恒定、可靠。（３）装置费用经济、节约。
In the paper a special kind of dynamic absorber is developed, which the natural frequency can be controlled by adjusting the air pressure and the water in the tank. Model tests were conducted and the experimental results inducate that the hydrodynamic vibration absorber has the following advantages: ability of easily changing the frequency of the absorber3 reliability in vibration reduction and low cost.
