“Say your prayers” or get a rotor dynamics simulation engineer – how simulation ensures engines can survive vibrations

June 26, 2024

Failure of a rotor blade results in large vibration throughout the airplane, but the plane lands safety. How do rotor dynamics engineers make engines that are able to survive these vibrations? and how do the updates in Simcenter 2406 help?

Vibrations in Rotating Systems – When defects and harsh conditions break the symmetry of rotating systems

December 20, 2023

Simcenter 3D Rotor Dynamics can study simultaneous unbalance defects on different rotors in rotating systems at different speeds, as well as the natural unbalance that can be deduced from a deformed geometry (thermal bow or static bow) due to external factors such as applied loads and temperature.

Smooth vibrations in rotating systems – How to monitor clearance consumption

November 13, 2023

In this blog post, we present how to easily monitor the clearance consumption at specific locations on the full assembly, checking in real time that the rotor and stator do not enter come into contact.

Identify the peaks of harmonic response during operation of nonlinear rotor dynamics

November 8, 2023

In this blog, we shown the possibility of computing the harmonic response, Campbell diagrams, the critical speeds at which resonance occurs and the stability of a system that contains geometric nonlinearities coming from their bearings.

Common rotor bladed machines with cyclic symmetry

Advances in resonance and cyclic symmetry of bladed rotor assemblies – Simcenter 3D 2306

June 12, 2023

Cyclic symmetry can be used to reduce solve times of rotor dynamic simulations. With the latest updates to Simcenter 3D it is now easier to find the results you need.
