How Specialists Like AME Tackle Vibration Challenges

Ever hear the term “Like Clockwork”? This originates from the immaculate precision with which watches and clocks are built. Industrial mechanical systems such as diesel engines, gearboxes, motors, pumps, etc. are often quite similar, just on a much larger scale. While industrial mechanical systems typically have more room for error due to the conditions in which they operate, they can deviate from their “clockwork” state. These deviations, more often than not, present themselves through subtle yet telling signs such as vibration – which can cause a multitude of potential issues. For high-stakes machinery operators—be it a yacht captain, sea captain or an industrial plant engineer—these vibrations indicate a need for intervention, often in a language that requires unique expertise to decipher.

As specialists in tackling complex vibration challenges, AME's teams are well-versed in the art and science of decoding vibrations to ensure the continued smooth operation of vital equipment. But how does this process occur? What methods form the foundation of this diagnostic service?

In this blog post, we get into the meticulous process AME undertakes to address vibrations. 

Understanding Vibration Challenges

Before we get into the solutions, let's first understand the problem. Vibration challenges often manifest as atypical, repetitive, motion inconsistent with that of normal operations. This highlights that a machine is operating outside of its optimal parameters. Operational irregularities such as unbalance, misalignment, wear, and structural deficiencies can affect a wide variety of performance aspects, such as poor fuel/power consumption, poor/irregular flow of fluids, insufficient power, and unpleasant or even unsafe working conditions. The consequences of unresolved vibration challenges range from decreased performance/efficiency to outright machinery failure.

Common causes of vibration challenges span widely. They include issues with rotating components like shafts, propellers, or pulleys which can become imbalanced or misaligned due to wear, poor installation, or damage. Resonance, another key factor, is a situation where the forcing frequency of a machine matches its natural frequency. This will undoubtedly lead to vibration amplification and eventual failure. Understanding these root causes, as well as the inner workings of machinery, is the first step in diagnosis and resolution.

The Troubleshooting Process

Now let's break down the methodical process AME follows when confronted with a vibration challenge.

Initial Assessment
Our specialists begin by studying the technical details of a machine and its components. They then perform a broad survey, looking for obvious signs such as high noise levels, structural problems, or increased wear on components. This often involves a visual inspection in conjunction with the use of standard vibration measurement devices.

Data Collection and Diagnostics
Once preliminary observations are made, we move on to detailed data collection. Vibration analysis data is collected across multiple points of the machinery, and data is rigorously compared to established baselines or predetermined standards if baselines are unavailable. This phase can often involve a considerable amount of data processing, but is essential for determining the precise origin and nature of the vibration at hand.

Root Cause Analysis
Informed by diagnostic data, we focus on identifying the root cause. For instance, we might find that rubber elements of a coupling have gone bad, causing it to go out of balance, therefore transmitting harmful vibration to the overall system. Other times we discover that machinery foundations have insufficient stiffness to support the rotational forces put on it by the machinery application. This phase requires a deep understanding of machinery dynamics and the interaction of different components under different operational stresses.

Resolution Strategies
With the root cause established, our team develops strategies for mitigation and repair. These approaches can vary from precision alignment of components, to in-situ balancing of rotors, or even redesigning faulty parts. We place a strong emphasis on preventing reoccurrence by addressing both the immediate issue as well as any underlying systemic weaknesses. Think of it like a car leaking oil, you can keep filling it with new oil (immediate issue), but you’re also going to want to stop the leak (underlying weakness).

Verification and Monitoring
Once repairs or adjustments are complete, the system undergoes extensive verification testing to ensure that vibrations have been brought back to acceptable levels. Not only does this prove that the corrective actions were successful, it also provides a new baseline to compare to for future trending purposes. Furthermore, remote condition monitoring is often recommended for ongoing surveillance, providing a real-time window into the machine's health.

AME’s troubleshooting processes ensure that no stone is left unturned in the quest to resolve vibration challenges  effectively.

We urge those responsible for operating mission-critical machinery to view vibration analysis not as an additional expense, but as a strategic investment in the long-term health of their systems. Whether you're a captain, a plant engineer, or a fleet manager, understanding and responding to vibration challenges with the aid of specialists like us can be the difference between smooth operations and a disruptive breakdown.
