摘　　要：本文以超声相控阵检测某游艇舷侧板为案例,制作了7mm平底孔对比试块和横向分辨力试块,制定了超声相控阵接触法检测工艺,并得到该系统的横向分辨力为2mm。最终使用该工艺实施了超声相控阵检测。结果表明:超声相控阵技术能够可靠地检出玻璃钢船艇的内部缺陷。Taking the ultrasonic phased array testing of a yacht's broadsidepanel as an example,the comparative test block of Ф 7mm flat bottom hole and the transverse resolution test block are made,and the testing technology of ultrasonic phased array contact method is developed,and the transverse resolution of the system is 2 mm.Finally,ultrasonic phased array inspection is carried out by using this technology.The results show that ultrasonic phased array technology can reliably detect the internal defects of FRP boat.
