DESIGN AND DEVELOPMENT OF A MULTICONFIGURATION BEAM VIBRATION TEST SETUP

Over last few decades, significant work in the area of beam vibrations is reported. Uses of classical beam theories have been implemented to study the modal characteristics viz. mode shapes, frequency and damping. The change of modal characteristics provides an indication of structural condition based on changes in frequencies and mode shapes of vibration. This needs to be checked theoretically and validated experimentally with the specimens. In the present work, a setup for the beam vibrations with different configurations is developed economically. The setup can check many key parameters of beam vibrations. Further a case study is presented, whereby cantilever beam specimens with different materials are checked using FFT analyser on the setup developed and the results are validated using ANSYS package.
