FIELD: physics, measurement. ^ SUBSTANCE: invention is related to the field of instrument-making and may be sued to assess dynamic errors of low-size inertial systems, when it is required to use them in navigation devices and other control instruments. Device comprises platform rocking in two planes and installed on cross-like suspension, detectors of platform angular position in each axis and two motors with reducers, connected to crankshaft-link mechanisms that transform rotary motions of motors into angular motions of platform and installed on immovable base. Besides device comprises rolling bearing, which transfers angular oscillations to platform from crankshaft-link mechanism along one of axes without modulation of platform oscillations in the second axis. ^ EFFECT: provision of possibility to reproduce angular oscillations of rocking platform in two orthogonal planes that vary according to harmonic law in expanded frequency range. ^ 2 dwg |
