摘要

本文利用本构形式、线性理论、弹性理论和压电方程，研究了旋转对包覆薄膜的压电杆轴对称波的影响。引入势函数解耦径向和轴向运动方程。棒的表面覆盖着一层完全导电的材料。得到了PZT-4陶瓷纵向振动和弯曲振动的频率方程，并对其进行了数值研究。计算得到的无量纲频率、相速度、相对频移、机电耦合和电位移以色散曲线的形式表示。这种类型的研究对旋转传感器和陀螺仪的构造具有重要意义。

Influence of Rotation on Transversely Isotropic Piezoelectric Rod Coated with a Thin Film

In this paper, the influence of rotation on axisymmetric waves of a piezoelectric rod coated with a thin film is studied using constitutive form linear theory elasticity and piezo-electric equations. Potential functions are introduced to uncouple the equations of motion in radial and axial directions. The surface area of the rod is coated by a perfectly conducting material. The frequency equations are obtained for longitudinal and flexural modes of vibration and are studied numerically for PZT-4 ceramics. The computed non-dimensional frequency, phase velocity, relative frequency shift, electromechanical coupling and electric displacement are presented in the form of dispersion curves. This type of study is important in the construction of rotating sensors and gyroscope.

期刊介绍： Engineering Transactions (formerly Rozprawy Inżynierskie) is a refereed international journal founded in 1952. The journal promotes research and practice in engineering science and provides a forum for interdisciplinary publications combining mechanics with: Material science, Mechatronics, Biomechanics and Biotechnologies, Environmental science, Photonics, Information technologies, Other engineering applications. The journal publishes original papers covering a broad area of research activities including: experimental and hybrid techniques, analytical and numerical approaches. Review articles and special issues are also welcome. Following long tradition, all articles are peer reviewed and our expert referees ensure that the papers accepted for publication comply with high scientific standards. Engineering Transactions is a quarterly journal intended to be interesting and useful for the researchers and practitioners in academic and industrial communities.
