Abstract
This paper develops the solution for the generalized thermoelastic vibration of an axially moving microbeam resonator induced by sinusoidal pulse heating. The system of governing equations is reduced to a novel six-order thermoelastic di r erential equation in terms of either deflection or temperature. The Laplace transformation method is used to determine the deflection, temperature, axial displacement, and bending moment of the microbeam. The e r ects of phase-lag and width of the sinusoidal pulse are studied and represented graphically. The e r ect of the moving speed on the microbeam resonator is also investigated.
