Application of SVD-TLS Based Parameter Estimation Method in Aircraft Structural Modal Parameter Identification

Abstract:

Structural modal analysis is an important element in design and testing of an aircraft, but the determination of the model order is a difficulty, in order to solve this problem, this paper advanced a Singular Value Decomposition and Total Least Squares combined method to determine the model order, and then identify the aircraft structural modal parameters. Simulation in using of aircraft flight test telemetry vibration data prove that the model order determined by this method is reasonable, and can be used to aircraft structural modal parameters identification.
