摘　　要：为实现对金属板材的产品质量进行准确快速的检测,利用有限元法建立电涡流测厚系统的理论模型。根据涡流检测的原理分析发现,金属板材的厚度与探头电感值存在密切联系。仿真主要研究金属板材厚度变化对探头电感值的影响,仿真结果表明,在合适的同一频率下,探头电感值随着金属板材厚度的增加而减小。In order to detect product quality accurately and fast,a finite-element model is established for thickness measurement using eddy current technique. According to the principle of eddy current testing,thickness of the tested sheet is closely related to the probe inductance value. Then,with the established model,the influence of thickness of the tested sheet on the probe inductance value is investigated. The simulation results show that the probe inductance value decreases when the tested sheet becomes thicker.
