Abstract

The vibration a paper machine generates during normal operation presents a complicated challenge to engineers of paper machine support structures. The modeling and the analysis procedure inevitably involves many simplifications and assumptions. Therefore, a comparison of the calculated and the measured results is very helpful in assessing the validity of the overall approach. This paper discusses correlation of calculated paper machine vibration with actual field measurements for a specific paper machine installation. A force-response analysis was performed using a commonly accepted industry practice which is generally considered to be conservative in several areas. Subsequently, field vibration measurements were made. The vibration data were recorded at strategic locations of the paper machine and compared with the calculated values. The comparison confirms that the measured results are indeed conservative as compared to the calculated values. Key parameters that affect the predicted results are also discussed in the paper.

Correlation of Foundation Vibration Results

St. Louis, Missouri

The vibration a paper machine generates during normal operation presents a complicated challenge to engineers of paper machine support structures. The modeling and the analysis procedure inevitably involves many simplifications and assumptions. Therefore, a comparison of the calculated and the measured results is very helpful in assessing the validity of the overall approach. This paper discusses correlation of calculated paper machine vibration with actual field measurements for a specific paper machine installation. A force-response analysis was performed using a commonly accepted industry practice which is generally considered to be conservative in several areas. Subsequently, field vibration measurements were made. The vibration data were recorded at strategic locations of the paper machine and compared with the calculated values. The comparison confirms that the measured results are indeed conservative as compared to the calculated values. Key parameters that affect the predicted results are also discussed in the paper.
