PROCESS OF THREE-COMPONENT VIBRATION REPRODUCTION Russian patent published in 2008 - IPC G01M7/06 

FIELD: physics.

SUBSTANCE: process of three-component vibration reproduction for a test object with assistance of one vibroexciter creating vibration acceleration along its axis. Amplitude of acceleration to be created is calculated by the formula where n₁, n₂ and n₃ are given components of vibration acceleration vector in the central orthogonal axes of test object. Acceleration is transmitted by the central orthogonal axes of test object with the help of a platform, the base surface of which holds test object fasteners and forms dihedral angle with the base surface of fixation to vibroexciter stand, while the test object is fixed to the platform so, that one of the object's central coordinate axes coincides with vibration acceleration direction and forms an angle .

EFFECT: higher accuracy of test mode reproduction; simplification of vibration test procedure and reduction of necessary number of tools.
