Abstract

Finite element techniques were used to analyze the dynamic characteristics of hollow tapered isotropic and composite shafts. Mathematical models of hollow tapered isotropic and composite shafts were developed, which were then discretized using Galerkin's Method to produce standard vibration equations. The solutions to the standard vibration equations were coded into two com puter programs, which can be used to calculate the torsional dynamic characteristics of an isotropic rotor system, and the coupled axial-torsional dynamic characteristics of a composite shaft. Several examples using each computer program are presented, illustrating their ability to predict natural frequencies and mode shapes of torsional systems.
