Primary objective of the work is to design, fabrication and testing of a 3-dimensional Mechanical vibration test bed.
Vibration testing of engineering prototype devices in mechanical and industrial laboratories is essential to understand the
response of the envisioned model under physical excitation conditions. Typically, two sorts of vibration sources are
available in physical environment, acoustical and mechanical. Traditionally, test bed to simulate unidirectional acoustic
or mechanical vibration is used in engineering laboratories. However, a device may encounter multiple uncoupled and/or
coupled loading conditions. Hence, a comprehensive test bed in essential that can simulate all possible sorts of vibration
conditions. In this article, an electrodynamic vibration exciter is presented which is capable of simulating 3-dimensional
uncoupled (unidirectional) and coupled excitation, in mechanical environments. The proposed model consists of three
electromagnetic shakers (for mechanical excitation). A robust electrical control circuit is designed to regulate the
components of the test bed through a self-developed Graphical User Interface. Finally, performance of the test bed is
tested and validated using commercially available piezoelectric sensors.
