Abstract
In this work, an attempt has been made to determine the mode shapes of a beam by experimental roving impact tests without using an FFT analyzer. The roving impact test was performed by acquiring the vibration using the National Instruments data acquisition system (NIDAQ) and LabVIEW. The acquired data was subjected to post-processing using MATLAB to determine the mode shapes. The mode shapes were determined using both roving accelerometer and roving hammer impact tests. The results were found to be in good agreement with each other. The numerical modal analysis of the beam was also carried out using the finite element package, ANSYS and compared with the experimental results. The maximum percentage error in natural frequency was found to be 4.26%.
