摘要
以方板为例,研究了换能器激励面积对板面节线分布的影响.结果表明:换能器激励面积影响方板节线分布,当激励源频率不变时,方板表面节线随激励面积的变化而变化,随着激励面积的增加,节线组成的圆角正方形不断减小.
Taking the square plate as example,the effect of transducer excited-area on the distribution of nodal line is studied by using the finite element method.It′s shown that when the excited frequency is fixed,the location of the nodal line changes with the different excited-area,the rounded square consisted of nodal line decreases when the excited-area constantly increases.
