When collecting vibration data with an FFT analyzer, a linear averaging process is used to reduce noise in the vibration spectrum. This video discusses signal processing, averaging and the Fast Fourier Transform in the vibration data collector..
Surface morphology is a detailed study of a surface. We studied the surfaces of railroad tracks and found that using analytical imaging helps us see what we cannot see with our naked eyes…
This case study comes from a custom-made, four-story-high pump at Engro Fertilizers. In January 2014, we started noticing abnormal noise and vibration from the gearbox. But we couldn’t see anything apart from an increased gear mesh frequency…
In large cities in India, such as Delhi, metros cause a lot of damage to buildings. Stories have appeared on the news of people who have to repair their houses again and again…
The mounting of a vibration sensor directly impacts its performance. Incorrect mounting may give readings that relate not only to a change in conditions but also to...
Acceleration enveloping is the sophisticated signal processing technique that helps to pinpoint bearing failure at an early stage. Below is a guide of how to successfully implement it...
