Application of group-theoretical analysis to certification of electrodynamic seismic receivers of accelerations

The paper presents a group-theoretical approach to the problems of metrological support for electrodynamic seismic receivers of accelerations. Symmetry groups in the equation of motion of the seismic receiver sensing element were found: translation (transfer) group, nonuniform extension (dimensional scaling) group, and the Galilei group. The proposed technique was developed to define parameters of the CBU-1 seismicreceiver of vertical accelerations using a vibrobench certified by the Gosstandard (National Standards Agency) authorities on state reference standards.
