状态监测传感器的计算机建模可以帮助其开发，提高其性能，并允许分析传感器对组件操作的影响。本文详细介绍了用于基于导波的温度监测系统的 COMSOL 模型的开发，以期将来将该技术用于航空发动机热部件中喷嘴导流叶片的温度监测。该模型基于实验测试系统，该系统充当模型验证的方法。压电楔形换能器用于在铝板中激发兰姆波模式，并使用热板控制温度。飞行时间测量在 MATLAB 中进行并用于计算群速度。将结果与从色散曲线提取的理论波速进行比较。这种模型的组装和验证有助于未来基于导波的传感器系统的开发，并且所提供的方法可以作为构建类似 COMSOL 模型的指南。结果表明，该模型与实验等效值吻合较好，也符合理论预测。
The computer modelling of condition monitoring sensors can aide in their development, improve their performance, and allow for the analysis of sensor impact on component operation. This article details the development of a COMSOL model for a guided wave-based temperature monitoring system, with a view to using the technology in the future for the temperature monitoring of nozzle guide vanes, found in the hot section of aeroengines. The model is based on an experimental test system that acts as a method of validation for the model. Piezoelectric wedge transducers were used to excite the Lamb wave mode in an aluminium plate, which was temperature controlled using a hot plate. Time of flight measurements were carried out in MATLAB and used to calculate group velocity. The results were compared to theoretical wave velocities extracted from dispersion curves. The assembly and validation of such a model can aide in the future development of guided wave based sensor systems, and the methods provided can act as a guide for building similar COMSOL models. The results show that the model is in good agreement with the experimental equivalent, which is also in line with theoretical predictions.
