摘　　要：针对难以一次定位的曲面形工件的超声检测 ,提出了一种双探头超声寻位检测方法。对涉及的一些问题给出了可行的解决办法。开发了相应的检测软件 ,并进行了仿真实验。理论分析与仿真结果表明 ,该方法是切实可行的。To resolve the non-destructive testing problem of the curved surface parts that are difficult to decide positioning, a non-destructive testing method of two probe continuous ultrasonic searching is put forward. The resolution is provided for some key problems included in this method. As a result, the testing software is developed, and consequently is used to do the testing simulation for a columnar part. The theoretic analysis and calculation results show that the testing method is feasible.
