FEATURE: Finite-Element Analysis Tool for Utility Rotordynamic Evaluation. Volume 2. FEATURE/COJOUR workshop notes
The FEATURE computer program (Finite-Element Analysis Tool for Utility Rotordynamic Evaluation) is a flexible, user-oriented tool for analysis of rotor-bearing systems. The program performs linear critical speed, damped response, and stability calculations for a wide range of rotor geometries, including multiple, concentric, counterrotating spools and large, multispan, rigidly coupled rotors. A finite-element formulation gives the program excellent numerical stability and the use of static substructuring greatly reduces run time. The COJOUR computer program is to provide a technically sound means for determining dynamic coefficients for use in the FEATURE code. It is capable of solving a wide variety of fluid film journal bearing configuration including both fixed-pad and tiling-pad types with or without thermal effects. The program will give comprehensive output such as load capacity, power loss, stiffness and dampling coefficients, etc.
