摘要

这项工作的主要目标是分析使用商业上可用的langasite (La3Ga5SiO14)和langatate (La3Ga5.5Ta0.5O14)压电晶体作为车辆重量传感器中动态敏感元件的可能性，作为已经证明用于此目的的石英晶体的替代品。为此，我们使用有限元模拟(在COMSOL Multiphysics 5.6软件中)和分析模拟，分析并比较了在langasite、langatate和石英晶体表面获得的输出信号的振幅。结果表明，在动态称重中，langasite和langate晶体可以与石英晶体同等使用，从而获得定性的汽车重量测量结果。

Study of the Possibility of Using Langatate and Langasite Crystals as a sensing element in Vehicle Weight Sensors in Dynamics

The main goal of this work is to analyze the possibility of using commercially available piezoelectric crystals of langasite (La3Ga5SiO14) and langatate (La3Ga5.5Ta0.5O14) as a sensitive element in vehicle weight sensors in dynamics, as an alternative to the already proven quartz crystals used for this purpose. For this purpose, we analyzed and compared the amplitudes of the output signal obtained at the faces of langasite, langatate, and quartz crystals using finite element simulations (in COMSOL Multiphysics 5.6 software) and analytical simulations. The results show that langasite and langatate crystals can be used on a par with quartz crystal to obtain qualitative results of vehicle weight measurement in dynamic weighing.
