Abstract
A mathematical model, based on Timoshenko beam assumption and the energy approach, for a rotating cylindrical shaft with cylindrical constrained layer damping treatment is developed. The model is developed for a shaft made from composite materials, and treated with a cylindrical constrained layer damping partially covering the length of the shaft. The discrete equations of motion are developed using the assumed mode method. The developed equations are applied to study the effect of the constraining cylinder's material and some geometric parameters on enhancing the dynamic characteristic of the shaft; more specifically, on the bending stiffness and damping of the shaft. The results, in general, indicate that the proposed treatment can be effective in enhancing the dynamic performance of the shaft. Also, results indicate that for best (bending stiffness and damping) performance, optimized parameters (length, thickness, material properties) are needed.
