NX Nastran for Femap - Rotor Dynamics
Rotating systems are subject to gyroscopic forces such as Coriolis and centrifugal forces that are not present in stationary systems. NX Nastran® Rotor Dynamics software provides the capability to predict the dynamic behavior of rotating systems. With the Rotor Dynamics functionality now integrated into NX Nastran, users can now more easily simulate rotating system loads, perform synchronous and asynchronous analysis to generate Campbell Diagram data, predict whirl frequencies and critical speeds and detect instability in rotating components.
Benefits
- Rapidly evaluate and improve the dynamic performance of rotating systems prior to physical prototyping and production commit
- Troubleshoot dynamicsrelated noise and vibration problems in previous designs as well as current in-production rotating equipment systems
- Evaluate and develop optimal in-service design modifications to increase production process throughput of rotating equipment systems
- Evaluate rotor imbalance and study general excitation response
- Compute critical speeds and whirl frequencies from Campbell diagrams
- Evaluate in-flight maneuvering loads on an engine rotor and simulate engine blade-out conditions
- Perform multi-disciplinary structural design analysis and optimization within the unified NX Advanced Simulation environment leveraging NX integration capabilities and using a single common CAE interface
