ABOUT VIBRATIONS OF COMPOSITE BAR IN PLAN MOTION

D. Bolcu, D. Tarnita

Abstract

The vibrations analysis has become one of the most important parameters to be considered during the machines designing process, especially in the case of high velocities. The use of the composite materials that posses high resistance and low specific weight, represents a solution to the above mentioned problems. In this paper, the mathematical model for composite bars presenting constant section, is described by a equation. The dynamic response is obtained using the Laplace transform and the sinuses finite Fourier transform of the spatial variable. The experimental treatment are made with a BK2515 vibration analyzer, the measures being in the time mode (0…12.5) sec and in the frequency mode, in the interval (0…1000) Hz.
