【 摘 要 】

The paper describes a sound vibration modulator to control turbodrill revolutions during turbine motor drilling. The principle of the modulator operation is based on the quarter-wave acoustic resonator property to suppress noises at the resonant frequency. A resonant chamber, which is a quarter-wave acoustic resonator, is embedded into the sound vibration modulator to control the number of turbodrill revolutions. The resonant chamber is a hollow cylinder with two cavities: an internal closed annular cavity and a central cylindrical cavity. During each revolution of the turbodrill shaft absorption of sound energy occurs at a frequency equal to the resonant chamber frequency, i.e. it creates a wave break. The number of these breaks will be equal to the number of turbodrill revolutions.
