What does an increase in vibration amplitude usually indicate?

An increase in vibration amplitude is typically a sign that a machine may be experiencing some form of distress or problem. This could be due to various factors such as imbalances, misalignments, or mechanical failures. When a machine operates normally, the vibration amplitude tends to remain within a specific range that is characteristic of healthy operation. However, significant deviations from this range—especially increases in amplitude—often signal that something is wrong and requires further investigation.

Monitoring vibration amplitude is a crucial part of predictive maintenance, as it directly relates to the health and functionality of machinery. Timely detection of increased vibration can prevent costly breakdowns and extend the lifespan of the equipment. Therefore, the presence of high vibration can indicate potential machinery issues or imbalances that should be addressed to maintain optimal performance and safety.
