| Abstract: | The transverse vibration of axially moving Timoshenko beams is investigated based on the boundary conditions for two edges simple supports. The coupled planar motion is analyzed by the differential quadrature scheme.The numerical examples show the first five natural frequencies are affected by the axially moving speed.The effects of the net-point number on the first five natural frequencies are discussed.The analytical results were confirmed by the numerical calculations . |
