ACTIVE VIBRATION DAMPING SYSTEM Russian patent published in 1998 - IPC

FIELD: mechanical engineering; facilities for active damping of vibrations. SUBSTANCE: vibration-active base mounts flexible support for equipment to be protected against vibrations. System also incorporates magnetoelectric converter, controlled voltage changer, equipment vibration sensor, and differentiating link. Newly introduced in system are pressure sensor, pressure controller, vibration regulator, and comparison unit; novelty is also that flexible support is adjustable part provided with rigid tank and flexible pneumatic member both filled with compressed gas, their working spaces being separated by moving diaphragm with throttling hole. In the course of system operation, magnetoelectric converter creates force displacing moving diaphragm which changes pressure in flexible pneumatic member thereby preventing displacement of equipment being protected against vibrations. EFFECT: improved design. 5 dwg
