| Abstract: | The power flow charateristic of beam-plate coupling structure is studied. The differential transform is used to solve the vibration problem of the non-uniform beam. The power flow characteristic of beam-plate coupling structure is discussed. The effect of the parameter variation of nonuniform beam and the position difference on the power flow is discussed in detail by numerical simulation. The results obtained provide the basis for reducing vibration of the non-uniform beam-plate assembly in engineering design. |
