Abstract

In this paper, dynamic analysis of simply‐supported COMPOSITE SANDWICH BEAM under a moving mass including ROTARY INERTIA and transverse shear deformation are investigated. Governing equations are gained using Hamilton’s principal. Modal superposition method used to deriving ordinary differential equation of motion in matrix form. Fourth order Runge‐Kutta method applied to solving the ODE with time varying coefficients. Parametric studies such as effects of stacking, aspect ratio, core thickness and stiffness, mass and speed of moving load on the midpoint deflection, dynamic magnification factor and CRITICAL SPEED have been studied. The obtained results show that core thickness and stiffness have considerable effects on CRITICAL SPEED. Inertia of moving mass has distinct effects on dynamic response of beam depend on load velocity.
