The article analyzes the performance of a negative-stiffness vibroisolating table in the range of a frequency of 2–110 Hz and reviews other possible ways of vibroisolating. The paper deals with conducted experimental tests on the transmissibility of vibrations employing specific tested equipment for vibration excitation enabling to execute research facilities. The article also describes the methodology of experimental tests and presents the obtained results and conclusions of experimental analysis.
