RISAccuracies of Reduced Order Models of a Bladed Rotor With Geometric Mistuning
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The results from a reduced order model based on frequency mistuning are compared with those from recently developed modified modal domain analysis (MMDA). For the academic bladed rotor considered in this paper, the frequency ...

Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper deals with further development of modified modal domain analysis (MMDA), which is a breakthrough method in the reduced order modeling of a bladed rotor with geometric mistuning. The main focus of this paper is ...
Geometric Mistuning Identification of Integrally Bladed Rotors Using Modified Modal Domain Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Modified modal domain analysis (MMDA) is a novel method for the development of a reduced order model of a bladed rotor with geometric mistuning. This method utilizes proper orthogonal decomposition (POD) of coordinate ...
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 ...
