摘要
将声发射技术应用于常压储罐罐底板特性的在线检测中,不仅体现该技术的方便快捷等特点,同时可以对整个储罐的底板特性进行评价,包括有无泄漏迹象、活性源信号的中心频率、摩擦噪声信号的中心频率及信号的传播途径等。
Acoustic emission as to apply to atmospheric storage tank flat bottom tank floor characteristic inspection, it can not only show the character of super fast -highly flexible, but also evaluate the whole characteristic of the tank floor, including the leakage, the central frequency of the activity source, the central frequency of the friction source and signal spread path.
