Rotor dynamics analysis software provides a digital model to assess the survivability of the rotating system in a wide range of situations, evaluate complex vibrations and instabilities under real operating loads. Rotor dynamics analysis software from Siemens provides powerful geometry editing functionalities, meshing, and solver technologies combined with user-friendly postprocessing capabilities to perform analyses efficiently.
Rotor dynamics analysis helps engineers to predict and prevent critical operating conditions of rotating machines.
Join this webinar and discover how an integrated multi-physics simulation solution addresses the rotating machinery manufacturer’s engineering challenges accurately and effectively while accelerating product time-to-market.
In this webinar, we demonstrate different types of rotor dynamics analysis in an integrated CAE environment, including:
- Critical Speed assessment
- Response to unbalance and misalignment
- Model reduction to save computation cost
Campbell diagram: compute the critical (or whirling) speed of rotating machines
The critical speed is the speed at which the system can become unstable, engineers must be able to accurately predict those speeds as well as to detect possible resonance problems before real commissioning.
Campbell’s diagram is used to identify critical speeds and shows how the frequencies of the complex modes change with the rotational speed of the rotor.
Perform synchronous and asynchronous rotor dynamic analysis to generate Campbell diagram data, predict whirl frequencies and critical speeds, and detect instability
Rotor stability and imbalance
Rotor instability is a dangerous phenomenon and reliable prediction of rotor stability is a challenging task especially due to the increased complexity of the system and component interdependence. Rotor dynamics analysis helps the engineer to get detailed insight into the origins of imbalance, its cause, and eliminate instability.
Suppressing unnecessary vibration of a finished prototype is often cumbersome and complex. Using a flexible rotor dynamics simulation software engineers can analyze rotor stability, vibration issues, and imbalance issues along the design cycle.
Address torsional vibration challenges of rotating machines
Rotating machines undergo torsional, axial, and lateral vibrations. Engineers need to perform sensitivity analyses i.e., analyze the vibration amplitudes during static and transient excitation of the system. The rotor dynamics simulation software permits users to evaluate the design modification impact on machine vibration before building an expensive physical prototype.
