In this study, after developing the mathematical platform and entering it into a computer, we can predict whatthe level of vibration should be if the pipeline that is being tapped is free of imperfectin. When the tap test isconducted on actual pipeline material and looked at the resulting patterns of vibrations, weak points couldquickly be identified. This method of attaching small machines to pipelines that are above ground and havingthem tap and measure vibrations offer a faster and cheaper way to find cracks or patches of internal rust thanthe conventional method of using imaging techniques.

在这项研究中，在开发数学平台并将其输入计算机后，我们可以预测如果被攻丝的管道没有振动，那么振动水平应该是多少。当在实际管道材料上进行敲击测试并观察由此产生的振动模式时，可以快速识别出薄弱点。这种将小型机器连接到地面上的管道上并让它们敲击和测量振动的方法比使用成像技术的传统方法提供了一种更快更便宜的方法来找到裂缝或内部生锈的补丁。
