THE ANALYSIS OF VIBRATIONAL RESPONSE OF STRUCTURES WITH UNCERTAIN PARAMETERS

This paper is based on study of vibrational responses of different vibrating systems at different frequency with uncertain parameters. The concept of uncertainty plays an important role in the design of practical mechanical system. So it becomes important to study its effects on mechanical system for different frequency domain i.e. low, medium and high frequency. There are large and varied amount of research has been dedicated to developing techniques which predict the dynamic responses of structures in all frequency domain and structures with uncertainty. Here in this paper structural element plate is selected on which mass and stiffness uncertainty are taking in account. By using FEM technique finding out, how plate is dynamically behaves in vibration.
