摘　　要：开展了基于波动法的油罐底板腐蚀检测技术研究,通过选择恰当的激励信号,有效地抑制多模式现象和频散现象,利用粘贴在油罐底板上的压电元件检测油罐底板的响应,从响应信号中识别损伤信息,从而确定出底板中的损伤。基于波动法的油罐底板腐蚀检测技术将为快速检测油罐底板的腐蚀状况提供一种新的手段,并为油罐底板检测系统的开发奠定技术基础,具有工程应用价值。The corrosion detection technology plate of oil tank was studied. Using an array of based on wave propagation method for bottom PZT wafers affixed to tank bottom plate, some wafers acted as elastic wave generators, others receive the structural response information, then location the corrosion by this information. It will provide a new technical which can detect the corrosion in oil tank bottom plate rapidly, and this technology would lay a solid technical foundation for the health monitoring system of tank bottom plate.
