RISEstimation of Forcing Function for a Geometrically Mistuned Bladed Rotor Via Modified Modal Domain Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Modified modal domain analysis (MMDA) is a method to generate an accurate reducedorder model (ROM) of a bladed disk with geometric mistuning. An algorithm based on the MMDA ROM and a state observer is developed to estimate ...
Modified Modal Domain Analysis of a Bladed Rotor Using Coordinate Measurement Machine Data on Geometric Mistuning
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Modified modal domain analysis (MMDA), a reduced order modeling technique, is applied to a geometrically mistuned integrally bladed rotor to obtain its natural frequencies, mode shapes, and forced response. The geometric ...
