Stochastic vibration of laminated composite coated beam traversed by a random moving load

This paper deals with the random vibration of a simply-supported laminated composite coated beam traversed by a random moving load. The moving load is assumed to move with accelerating, decelerating and constant velocity types of motion. Using basic analytical techniques, this investigation aims at improving the random response of beams made from isotropic materials by using composite coats. Closed form solutions for the variance of the response is obtained. The results arrived at in this paper discuss the random vibration characteristics of the response of the aforementioned beam taking into account the speed effect, lamina thickness and orientation of the coat effects.
