IMPRO™
IMPRO (IMpeller PROgram) was developed to assist engineers in the structural assessment of radial flow impeller/compressor wheels. The program is a complete stand-alone finite element-based program for the interactive model generation and analysis specific to impeller wheels.Key Benefits
- Rapid model development for quick turnaround analysis
- Automated boundary condition application, relieving the user of this critical responsibility
- Ability for a non-FEA expert to successfully employee this analytical technique
- Faster time-to-market with more reliable products
Capabilities
Modeling Capabilities
- Both open and closed (shrouded) impellers
- Splitter blades
- Hub geometries with arbitrary back-plane profiles
- Variable blade fillet radii at both hub and shroud locations
- User control of mesh densities
- Both single sector and full wheel models
Analysis Capabilities
- Steady stress
- Natural frequency and Mode-shape calculation
- Dynamic stress
- Low- and High-cycle Fatigue calculations
Post Processing
- Intuitive stress and displacement viewing
- Point-and-click identification of result quantities
- Animated mode shape plotting
- Auto-generated interference diagrams
- Campbell diagrams
Miscellaneous
- Material properties database for common impeller materials with options for adding new materials
- Model translators to and from ANSYS®
- Automatic file handling by the program
Typical Uses of IMPRO
- Analytical design tool for producing structurally sound wheels
- Diagnostic tool for doing Root Cause Analysis (RCA) to explain why a blade, or wheel, has failed
- Redesign tool to verify proposed changes to a design
