Rotor dynamics analysis: Proven strategies to overcome engineering challenges faster and smarter - ERP Spain.com - España y América Latina

 

Rotor dynamics analysis helps engineers to predict and prevent critical operating conditions of rotating machines.

 

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.

- Critical Speed assessment

- Response to unbalance and misalignment

- Model reduction to save computation cost

 

 

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 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.

 

 

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.
