Abstract

A method has been developed for analyzing the elastodynamic response of high-speed flexible linkage mechanisms with piezoelectric sensors and actuators. The finite element analysis model is obtained by using a mixed variational approach with Hamilton's principle. An efficient solution method is developed on the basis of complex mode theory. A four-bar linkage mechanism with all flexible links is employed as an example to demonstrate the capability of the proposed method. The investigation provides a theoretical basis for complex mode active vibration control of high-speed flexible mechanism systems.
