多层结构复合材料的超声检测系统设计

Ultrasonic inspection system for multi-layer composite material

分析了超声波在多层结构复合材料中的传播特性,设计了测量多层复合材料厚度及各种缺陷的超声检测系统超声发射系统。该系统由超声波发射系统、接收系统及计算机控制处理系统组成。针对多层结构复合材料层厚及内部缺陷分别进行了计算机仿真和实测实验,并对实验结果进行了比对。结果表明,该检测系统性能达到了设计要求。

Based on the analysis of ultrasonic propagation characters in composite material,this paper presents a scheme of the ultrasonic inspection system for multi-layer composite material.Computer simulation and inspection experimental of 3-layer composite material indicate that the system can achieve inspection of multi-layer composite material efficiently.
