| Abstract: | The dynamic stability of axially moving beam under the action of axially load and temperature load are studied.The differential equation of motion of the axially moving beam under the action temperature load is found by using the D Alembert's principle.The character equation is given,the numerical values were calculated of the dimensionless complex frequency of simply supported beam using the Galerkin method.The effects to the natural frequency and stability of the transverse vibration beam by the dimension... |
