Review article

The article discusses the A. M. Kurzanov kinematic supports. Equations of vibrations of the protected object located on the A. M. Kurzanov supports are obtained through the Lagrange equations of the 1-st kind. There has been carried out a numerical analysis for 15 different earthquakes, which allows evaluating the efficiency of seismic isolation (reduction of the maximum absolute accelerations of the protected facility) and estimating mathematical expectation of absolute accelerations. The analysis has shown that with the help of the A. M. Kurzanov kinematic supports, on average, it is possible to reduce the peak acceleration by half. Some recommendations on the use and selection of parameters of kinematic supports are offered.
