摘要 基于相控阵对声束的控制原理,采用模拟软件CIVA对聚焦声场进行仿真。通过改变探头单组激发晶片数目、频率和聚焦深度,分析三者之间的关系;结合人工缺陷的实际检测结果,探讨聚焦与不聚焦检测的实施方法。试验表明,采用相控阵超声进行聚焦检测时存在焦点与最大声压位置的重合区和分离区,且最佳聚焦区域在近场区范围以内;不聚焦检测时应该根据缺陷的埋藏深度设置合理的单组激发晶片数目,以获得较好的检测效果。 On the base of beam controlled theory, ultrasonic phased array focusing testing was simulated by the software CIVA. By changing the number of stimulated elements, frequency and depth of focusing, the relationship among those was analyzed. The method of real testing in focusing mode and non-focusing mode was discussed with the result of manual defect testing. Study shows, that there exists area of superposition and separation to focal point and maximum acoustic pressure in focusing mode. The best effective area of focusing should be within the near field of ultrasound. In non focusing mode, the number of elements stimulated should be chosen according to the depth of defect.
