Optimization of structural parameters using artificial neural network for vibration reduction in beams

Abstract

Recently optimization of structural parameters like stiffness coefficient and damping coefficient, using artificial neural network for vibration reduction in beam has become a major application in aerodynamics and many other fields. By placing the PVC dampers of different cross sectional area at different locations along a beam, we have to minimize the response and the response time of the beam due to vibrations. Measuring factor of damping (reduction in vibration) is the LOSS FACTOR (Ω) for the system. Along the beam, where the loss factor is more, it gives us an optimal position for placing the damper. It also gives stability to the structure. The stability of the beam enhances due to increase in core loss factor also.
