| Abstract: | The coupled thermoelstic stability of the axially moving beam are investigated.The differential equation of motion of the axially moving beam under the thermoelastic coupling is established based to the equilibrium equation and the thermal conduction equation involving deformation term.The dimensionless complex frequencies of the axially moving beam with simply supported under the coupled thermoelastic case are calculated by the differential quadrature method,and the curves of the real parts and imaginary p... |
