We conducted synchronous and asynchronous frequency analysis of rotating bodies in a fixed coordinate system.
**Case Overview** ■Product Name: NX 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 dangerous speed point on the 1P line in the Campbell diagram. The latter involves a rotor rotating at a constant speed with varying excitation load frequencies, leading to rotor resonance at the intersection points of each mode with the vertical line in the Campbell diagram. □ For other functions and details, please refer to the catalog.
