Piezoelectric ceramics are used more in the active control of noise and vibration with sensors and actuators. As a result, a one-dimensional homogeneous thermoelastic fixed piezoelectric rod subjected to a moving heat flow has been considered. The heating rod is affected by three fields, namely, thermal, mechanical, and electric potential. In order to design a reliable smart structure, this study is necessary and the thermopiezoelectric behavior of piezoelectric ceramics must be understood clearly. The Laplace transform method is applied to acquire the distributions of stress, deformation, and temperature fields. The effect of heat source velocity and phase lag parameters on the considered physical fields is displayed graphically, and the results are compared with other models of thermoelasticity. The present findings could find possible applications for designing receiving portions of transformers of Rosen type for voltage magnification.

通过双相滞后模型暴露于轴向移动热源的热弹性压电固定杆

压电陶瓷更多地用于通过传感器和执行器主动控制噪声和振动。因此，已经考虑了经受移动热流的一维均匀热弹性固定压电棒。加热棒受热、机械和电势三个场的影响。为了设计可靠的智能结构，这项研究是必要的，必须清楚地了解压电陶瓷的热压电行为。应用拉普拉斯变换方法获取应力、变形和温度场的分布。热源速度和相位滞后参数对所考虑物理场的影响以图形方式显示，并将结果与​​其他热弹性模型进行比较。
