New design of active vibroprotection devices

A principally new design of active vibroprotection devices has been developed, which can overcome limitations with respect to the active frequency range and maximum vibration suppression coefficient, which are inherent in the existing devices. It is shown that these limitations are related to the parasitic signal of accelerometer inclination in the Earth’s gravity field. A method is proposed to compensate for this effect so that, even with simple electronic circuits, the lower frequency boundary of active vibroprotection decreases from 2 to 0.2 Hz and the maximum vibration suppression coefficient increases from 40 to 60 dB.
