[Example] Rotor Dynamics Frequency Analysis

We conducted synchronous and asynchronous frequency analysis of rotating bodies in a fixed coordinate system!!!

**Case Summary** ■Product Name: Simcenter Femap with Nastran ■Analysis: Frequency Response Analysis ■Industry: Other In this analysis example, synchronous and asynchronous frequency analyses of a rotating body in a fixed coordinate system were conducted. The former is an analysis where the rotation speed and the excitation load frequency match, resulting in a response peak at the danger speed point on the 1P line in the Campbell diagram. The latter involves a rotor rotating at a constant speed with a varying excitation load frequency, leading to rotor resonance at the intersection points of each mode with the vertical line in the Campbell diagram. □ For other features and details, please refer to the catalog.
