Abstract

Active control of low frequency line spectrum is an important technique for vibration and noise reduction.Based on theoretical study and finite element analysis for a maglev-air bag active-passive hybrid vibration isolator, special force-measuring fixture for the isolator was designed to conduct active control tests of the isolator and obtain its output force characteristics.Then, aiming at mechanical line spectrum vibrations, an active control method taking force as error signal was proposed and it was verified with tests.The test results showed that under the condition of taking force as error signal, the low frequency line spectrum control effect on transmitted force of the active-passive vibration isolation platform is good and the active control test platform’s low frequency line spectrum vibration can be reduced significantly.
