Abstract
En 中文
• A UAV motion elimination method based on structural self-reference points is proposed. • The paradigm shifts from precise displacement measurement to direct extraction of modal parameters. • The self-reference method distorts the mode shape but leaves the frequency and damping ratio unchanged. • A mathematical relationship is formulated for the identification of modal parameters. • The accessibility of the proposed method is verified by the numerical and experiment examples.
