Численный анализ свободных колебаний цилиндрической конструктивно анизотропной оболочки при различных граничных условиях

Abstract

The analytical solution of approximate natural frequencies for the free vibration of cylindrical shells of GFRP (glass fiber reinforced plastic) with clamped boundary conditions at one end and simple supported boundary conditions at another end is presented using the Rayleigh-Ritz method, while the winding angle varies. Frequency variations for different vibration modes with certain shell’s geometrical parameters are discussed. The effect of shell’s geometrical parameters is also investigated on natural frequencies.
