【 摘 要 】
Wave-type oscillations generated by a downhole unbalanced seismic source are studied on the laboratory test stand. The mode of source operation with an inner chamber filled with a fluid is investigated at shaft rotation frequency ranged from 3 to 8 Hz. The difference of rotation frequencies of vibration source and magnetic field of asynchronous motor stator is determined. The amplitude-frequency characteristic of the vibration source in the low-frequency range is obtained.
