摘　　要：建立了当涡流检测渗碳层深度时所涉及的有限元计算方程,开发了有限元软件进行计算和后处理,得到了不同渗碳层深度时的磁感应强度图。结果表明,渗碳层深度不同时磁场分布也不同,两者之间有较好的对应关系,计算结果与实验结果相吻合。A finite-element equation related to test of case-depth using eddy current is deduced. Software is developed to compute this equation and perform post-processing and magnetic induction intensity image with different case-depths is gained. The results show that the distribution of magnetic field differs according to the variation of case-depths and the calculation results well agree with the experimental ones.
