Machines have their own language. When operating, they’re constantly broadcasting signals of their status. To a large extent, machine health is about translating this language to understand where, when, why, and how a machine requires attention or intervention.
That’s where vibration analysis comes in. The source of a vibration, the direction (vertical, horizontal, or axial), and the vibration intensity can all indicate impending problems. For instance, if a shaft is supported by four bearings and one vibrates differently to the others, that bearing may be headed toward failure. If vibration analysts spot the problem in time, they can intervene early. If they don’t, however, preventable problems can turn into catastrophic failures.
More vibration data translates into better insights about machine health. Unfortunately, the sheer volume and velocity of the data available creates a serious obstacle in vibration analysis. When analysts have vibration data coming from many sources on a constant basis, it becomes an overwhelming effort to understand what it all means. In this circumstance, the amount of data manufacturers can analyze depends not on the actual amount available but rather on how much data analysts can handle. Much of the data goes uncollected, or unanalyzed, which means important insights go unnoticed.
How can analysts cover more data to gain better insights into machine health? Artificial intelligence in manufacturing is one possible solution.
AI Optimizes the Work of Vibration Analysts
AI and machine learning technologies excel at carrying out routine, repetitive tasks at high speeds on a massive scale. For the purposes of vibration analysis, the tools could instantly examine each piece of vibration data and identify whether it’s irrelevant (as much of it is) or an anomaly that requires analysts’ attention.
Such technologies can also handle the diversity of machinery present within manufacturing facilities and across facilities. Instead of being programmed to know what anomalous vibrations look like on every piece of machinery, AI can learn that information by studying the standard vibrations. Once it understands what the machine should be doing, it can easily identify when a vibration deviates from the norm. This makes AI widely applicable in diverse industrial settings and a perfect fit for vibration analysis.
3 High-Value Tasks Vibration Analysts Can Focus on With AI
AI isn’t a replacement for human vibration analysts, and we shouldn’t expect it to become one. Vibration analysis is nuanced work, and missing a problem can have serious deep consequences. Therefore, human analysts should always have the final judgment call about when or why to shut down a machine. Armed with AI, however, analysts can make those calls at exactly the right time and with a higher level of accuracy and precision. When they can spend less time collecting and analyzing data, they can also take on more high-value responsibilities in the following ways:
Imagine if there was advance warning of every developing machine health issue, a detailed action plan, and a facility-wide commitment to addressing it as quickly and completely as possible. Downtime would become extremely rare. AI-driven vibration analysis makes that vision possible.
