摘要
用有限元法对非均匀介质的涡流检测信号进行了数值模拟,并针对检测信号采用逼近的方法预测了表面硬化层深度。研究表明,这种方法与常规方法相比,有更好的可靠性。本文还给出了渗碳层深度的数值模拟实例。
The numerical simulation on the eddy signals was introduced by approaching method based on Finite Elements theory to predict the hardened depth. The experiments have proved the enhanced reliability of this method comparing with the routine solutions. An example of the numerical simulation of carburized layer was presented.
