Abstract: After analyzing Japan TOYOTA electronic shedding mechanism’s composing and working principle in detail,finds the eccentric four bar linkage shedding method of this mechanism is not the ideal one. Its nonlinear of motion transfer makes the servo-motor’s acceleration change rapidly at both the beginning and the end of the heald shaft’s shedding motion,which go against servo-motor's control. Special compensation method was needed to obtain the ideal shedding rule. Two innovated mechanisms which transfer motion by linear or nearly linear was designed. Through numerical analysis and mechanism kinematic emulation results,it proves that the innovated ones have better performance in control and motion transfer.
