Comprehensive Evaluation of Machinery Noise and Vibration Issues

2025年5月26日

Noise and vibration are not only annoying but can also lead to reduced energy efficiency in machinery.

Rotating machinery such as turbines, gears, and pumps often cause unpleasant vibrations and raise concerns about durability.
Analyzing these machines can be challenging, as underlying usage patterns are not always immediately apparent.

By appropriately combining analysis tools across the time, frequency, and order domains, it is possible to highlight performance characteristics and enhance product performance.

Vibration must be measured and evaluated because it can directly cause problems, or because structures and products are required to comply with standards and testing specifications.

Vibration testing and monitoring provide valuable insights into the internal world of vibrations within products, machinery, and structures, helping manufacturers ensure the quality, reliability, and durability of their products and components.
