摘要
压电换能器在工作过程中的发热,不仅会引起换能器的性能下降,而且还可能导致换能器失效。基于传热学的基本理论,应用ANSYS有限元分析软件,建立了压电换能器的热分析模型。采用有限差分的数值求解方法,对换能器的整体温度场进行了求解,分析了前后质量块采用不同材料的Langevin换能器的温度场分布规律,为大功率压电换能器的散热和性能优化方法的研究提供了基础。
The heating of piezoelectric transducer not only lowers the efficiency of these devices, but may also lead to their failure. Based on the heat transfer equation, the FEM thermal analysis model of piezoelectric transducer was established by means of ANSYS. The temperature field distribution of Langevin transducers with various material types was analyzed. The work provides a foundation for the thermal analysis and optimization of large power piezoelectric transducers.
