Normal Modes Analysis of a Propeller

This tutorial demonstrates a simple normal modes analysis of a propeller.

  1. The goal of this analysis is to determine the natural frequencies of the propeller with the center hole fixed by eigenvalue extraction.
  2. The propeller is made of stainless steel.
  3. The units used in this analysis are inches, pounds and seconds (in-lb-s). The effects of gravity are not considered in this model; however, the mass of the part is.
