Abstract：A new method for calculating the bending vibration of beams is proposed in this paper. A calculating model for non-uniform beams is established using finite difference method; the model can also be used for uniform beams. Some examples show that the model has good precision. Meanwhile, mode shape optimization is implemented to non-uniform beams using the pre-established model. By changing the function’s form of the model, it’s possible to get the best thickness distribution to obtain an expected mode shape. An example shows that the method is effective and practicable.
