Based on ANSYS Large Diameter Metallic High-Speed Rotating Disk Modal Analysis

Abstract:

The modal analysis for rotating disk with pre-stressed in different high speeds were made respectively based on the finite element software of ANSYS. The each order natural frequencies and inherent vibration were revealed. The result shows that disc rotation speed increases, the each order natural frequencies will also increase, and inherent vibration corresponding changes. By introducing the disc frequency deviation factor, the effect of stress stiffing effect for the disc natural frequencies and inherent vibration were analyzed and found that relationship of a quadratic curve between disc frequency deviations and speed.
