Abstract

Vibration effects include unwanted behaviour such as improper working, early failure, noise problems etc. System performance decreases due to vibrations. Therefore, we need to understand the vibration pattern of structures, which is a function of natural frequencies as well as mode-shapes. Such understanding is must for developing a good design. Mode-shapes helps us in understanding the way in which is structure is going to vibrate when put under free or forced vibrations. This paper presents a basic work related to development of Matlab program which can be useful for analysing the natural frequencies and mode-shapes of a free-free beam. Extreme as well as a number of intermediate positions of mode shapes of the free-free beam structure have been plotted. The work is supposed to be helpful for beginner researchers to understand the mode-shape analysis of beams.
