Dead-center Positions of Six-bar Linkages Based on Instant Centers

Guo Xiaoning Zou Yanhuo Dou Ning Fuzhou University,Fuzhou,350108  
Based on the relation of mechanical efficiency and instantaneous centers,the necessary geometric conditions for the instantaneous centers of a linkage when it was in dead-center positions were given.This methodology avoids the handling of complicated algebraic equation and remains valid for the mechanisms with prismatic joints provided instantaneous centers can be located.Based on the method possible configurations of the six-bar linkage in dead-center positions were listed,and this method presents a way for the problem of whether a crank exists in a mechanism.
