Abstract
The experimental research has been carried out in two steps. In the first step, we designed and we studied in laboratory a mathematical model to reproduce a real situation of the fan insulation. In the second step, we made experimental investigations on the spot. Comparing the measured vibration amplitudes to those obtained on mathematical model, we identified a hidden connection near one of cassettes with coil springs. The hidden connection has appeared during the cassettes mounting and so was created a mechanical asymmetry. Due to this, the dangerous levels of vibration have occurred and it was caused a temporary shutdown of the fan. The process for detecting and eliminating the mounting nonconformities it is presented in the paper.
