BladePro-CF flutter _ An ANSYS-based Impeller Analysis System.pdf

|
This paper presents the architecture and capabilities of BladePro-CF, an ANSYS based analysis systemdeveloped to assist engineers in the structural assessment of radial and mixed-flow impellers. Theautomated tasks include: finite element model generation, boundary condition application, file handling andjob submission and queuing of analysis jobs, and impeller-specific post-processing tools. The FE modelgeneration features both open and closed (shrouded) impellers, multiple splitter blades, hub geometrieswith arbitrary back-plane profiles, variable fillet radii at both hub and shroud surfaces, user controllablemesh densities, and definition of blade surfaces using multiple streamlines. Also, both single sector and fullwheel models can be generated. The analysis capabilities include steady and vibratory stress calculation, frequency and mode shape calculation, and low-and high-cycle fatigue life predictions . BladePro-CFincludes impeller-specific post-processing capabilities such as intuitive stress and displacement viewing, animated mode shape plotting, auto-generated interference and Campbell diagrams. This paper uses a realworldapplication to demonstrate these capabilities. BladePro-CF can be primarily used as an analytical toolfor facilitating the design of structurally sound wheels, a diagnostic tool for doing Root Cause Analysis (RCA) to explain why a blade, or wheel, has failed, and a redesign tool to confirm the improvement of anexisting design.
