Xm. Zhang et al., A HIGH EFFICIENT FREQUENCY-ANALYSIS METHOD FOR CLOSED FLEXIBLE MECHANISM SYSTEMS, Mechanism and machine theory, 33(8), 1998, pp. 1117-1125
Frequency analysis is an important step to predict the dynamic perform
ance of flexible mechanisms. According to the characteristics of the d
osed flexible mechanisms, an efficient frequency analysis method for p
lanar multi-bar and spatial linkage mechanisms by utilizing free-inter
face substructure coupling technique, substructure division and the mo
dal basis generation method are presented. Coupling equations for typi
cal substructures are developed. Examples show that the analysis metho
d presented in this paper is effective. (C) 1998 Elsevier Science Ltd.
