MULTIDIRECTIONAL TESTING VIBROSTAND Russian patent published in 2008 - IPC G01M7/06 

FIELD: technological processes; measurement.

SUBSTANCE: invention is related to the sphere of structures testing for vibration, namely, to structure of multi-directional testing vibrostands. This technical solution is aimed at creation of vibrostand, which generates three-component linear vibrations on the tested item with application of one vibroexciter, which generates vibrations along its axis and allows to increase the accuracy of test modes reproduction, to simplify the design of vibrostand, to exclude the necessity of synchronous control system for several vibroexciters. In order to achieve the mentioned technical result, in testing vibrostand that includes vibroexciter, platform that has base for connection with vibroexciter table and base with assembly units for fixing of tested object, plane of platform base with assembly units for fixing of tested object creates with the plane of base for connection with vibroexciter table dihedral angle where n₁, n₂, n₃ - components of preset vibration accelerations in central orthogonal axes of tested object, at that the fixture units are made with the possibility of object installation so that one of its central orthogonal axes n₁ that matches direction of vibration accelerations n₁, creates angle with rib of dihedral angle .

EFFECT: creation of multi-directional testing stand, which allows to increase the accuracy of test modes reproduction, to simplify the design of vibrostand, to exclude the necessity of synchronous control system for several vibroexciters.
