A New Non-Incremental Finite Element Solution Procedure for Rotor Dynamics

Abstract

The goal of this research project was to explore the use of a new finite element procedure in the analysis of rotor blades. The use of the large deformation finite element absolute nodal coordinate formulation in the analysis of rotating blades was examined. several important problems were identified and solved. and new challenges are encountered and discussed in this report. The developments made in this research project include introducing new reduced order thin beam and plate elements, improvements of the performance of existing full parameterized elements using different methods for formulating the elastic forces, implementation of the proposed formulations, formulation and implementation of new types of joints that are used in rotor blade models, and comparing the results of the eigenvalue analysis with existing finite element formulations.
