The Effects of Ply Angle of Laminated Composite Plates on Wind Induced Vibration
This paper presents an analysis on the effect of ply angle for laminated composite plates on wind induced vibration.With Hamiltons principle and the Rayleigh-Ritz method,the equation of motion for the wind induced vibration is derived.The displacements in time domain and the mean-square value of the transverse response under wind pressure are studied for laminated plates with different ply angles.From the numerically simulation results it is seen that the ply angle of the laminated plate can significantly affect the wind induced vibration.For different rectangle plate the optimal ply angles of minimum displacement is different.The analytical methodology in this paper can be expanded to other kinds of random vibration such as water flow induced vibration.
