What aspect does vibration analysis NOT typically focus on?

Vibration analysis primarily revolves around the study of mechanical vibrations in machinery and equipment to identify mechanical defects, assess operational efficiency, and monitor the effectiveness of corrective measures. The technique involves evaluating patterns of vibration that can reveal various issues such as imbalance, misalignment, and bearing wear.

Temperature fluctuations, although important in the broader context of equipment health monitoring, fall outside the primary focus of vibration analysis. While it's crucial to monitor temperature as it can impact machine performance and reliability, this particular aspect is more aligned with thermal analysis or condition monitoring techniques that specifically address thermal issues rather than the vibrations that the machinery experiences during operation. Thus, observing temperature fluctuations is not a core component of vibration analysis itself.
