It is shown that the effects of the stiffness and inertia of the piezoelectric element that lead to higher first natural frequency on the natural frequencies of the beam are significant, and that of the elastic modulus of the bonding layer is small.

• 研究表明，压电元件的刚度和惯量对梁的频率影响很大，变截面智能压电梁的一阶固有频率总是高于等截面梁的固有频率。
