摘要
将坐标变换理论引入到弯曲波的动力学方程中,推导了能控制弯曲波沿任意角度偏转的材料参数空间分布设计公式,建立了仿真计算模型并利用有限元分析软件对模型进行了数值仿真分析,结果表明,该波导设计方法对于弯曲波的控制十分有效,为薄板弯曲波的控制提供了新方法,
The coordinate transformation theory is introduced into the elastic dynamic equation of flexural waves,distribution of matrials in an elastic thin plate is calculated,which can make flexural waves deflect at any angle. The simulation model of the waveguide design is built,and it is analyst with finite element method.Results show that this method is effective on flexural waves control.
