🔎 For those new to the topic of Vibration Analysis, here's a great example of successfully combining CM technologies: MA + VA by Stuart Walker. The problem at hand involves elevated vibration levels in an Oven Infeed Motor and its adjacent structures, including guard rails, with a measured range of 10 to 100 mm/sec RMS. These vibrations could potentially lead to premature wear, reduced efficiency, and in worst-case scenarios, catastrophic machine failure. 📹 To visualise and quantify this problem, RDI Technologies Inc.'s IRIS M™ Motion Amplification® camera was used to offer a visual perspective of the vibrations, magnifying their movements to detect issues otherwise invisible to the naked eye. Complementing this, Emerson's Automation Technologies & Solutions AMS 2140 Analyser provided detailed data through transient run-up tests spanning from 0 to 37,000 Cycles Per Hour (CPH) and bump tests conducted with the machinery switched off. These tests are critical for pinpointing the vibrational issues at their source. 🛠️ The analysis led to a twofold recommendation. First, it was noted that the oven infeed stabilisation structure and guarding resonate at natural frequencies within the operational speed range of the oven infeed drive, which is suboptimal as it can amplify vibrations. The drive roll of the oven infeed, operating at a frequency of 1 times the Rotations Per Minute (RPM), is identified as the primary source of excitation force. 📊 To mitigate this issue, the recommendations were: either reduce the excitation force generated by the oven infeed drive roll or adjust the natural frequencies of the structure to be at least 30% different from the operational speeds, avoiding resonance. Implementing stiffening measures would serve to increase the natural frequencies, whereas adding mass would have the opposite effect, reducing them. These adjustments must be carefully calculated and implemented to ensure that the natural frequencies do not coincide with the excitation forces, thus effectively minimising the vibration and stabilising the system for reliable operation. 🔗 For a deeper dive into the technologies used in this case example, explore the capabilities of the IRIS M™ Motion Amplification® camera for visual diagnostics: https://lnkd.in/dwaq93E, and the AMS 2140 Analyser for advanced vibration analysis and data collection: https://lnkd.in/di7HCcs.
