“At RMS, we often get asked, “How does Motion Amplification™ fit within an existing PDM program?” Here is a great example. We were collecting baseline readings on a variety of rotating assets on a new print press using our AMS 2140 Analyser. We noticed one of the Oven infeed drives was showing raised levels around 10mm/sec RMS at 1XRPM, and the surrounding structure was also vibrating. At this point, we decided to get the IRIS M Camera out to visualize the vibration problem.

We filtered the videos to the running speed of the drive (40Hz) and were amazed to see the infeed structure, walkway, and guard rails all vibrating at 40Hz. Levels were between 10-100mm/sec! At this point, we suspected a resonance problem and decided to do a Transient run-up on the infeed structure. We noted two clear resonances at 32Hz and 42Hz, both in the operating speed range of the press. Next, we did a quick bump test on the structure with the machine off and confirmed the two natural frequencies at 32Hz and 42Hz. All the camera footage and tests were done within 30 minutes. The client was very happy, especially with the MA videos, which are so powerful in cases like this.” — Stuart Walker
