Rotordynamic Analysis with Shell Elements for the Transfer Matrix Method

Abstract

Shell finite elements were used to model conical sections with a range in parameters; axial length, radius, wall thickness, cone angle and Young's modulus. The parameters were chosen to cover the complete range of rotors, casings, and housings used throughout the turbomachinery industry. Flexibility coefficients were generated for these structures. The need for these flexibilities to be used in the current day rotor dynamics transfer matrix computer programs is demonstrated. The flexibility coefficients are presented in nondimensional tables and plots for ease in use by turbomachinery design engineers and analysts in industry. Theses.
