Abstract

Multi-exciter vibration systems provides access to simultaneous multicomponent calibration of motion transducers. Vibration control is an essential prerequisite to generate accurate spatial orbit motion for transducer calibration. Relationship of shapes and orientations of spatial orbits and amplitudes and phases of acceleration components is discussed. Multi-exciter vibration control for both cross-coupling compensation and amplitudes and phases control of acceleration components is investigated. The experimental results show that the proposed control method can efficiently reduce cross-coupling of the tri-axial vibration exciter and a variety of spatial orbits can be generated.
