Thermoelastic Vibration of an Axially Moving Microbeam Subjected to Sinusoidal Pulse Heating

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 differential 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 effects of phase-lag and width of the sinusoidal pulse are studied and represented graphically. The effect of the moving speed on the microbeam resonator is also investigated.
