Abstract: Abstract: The ellipse gear-sine mechanism is used usually in conducting bar mechanism of wool spinning gilling machine so as to meet requirements of uniform motion of conducting bar implement. The process of the design and analysis of this mechanism is very complicated if only graphic means or math analysis is used. This paper has been described the method in which the kinematical behavior of a conducting bar mechanism is analyzed with MAPLE. According to the curve of the mechanism’s drive function, all parameters has been selected experientially. Then, optimizing these parameters so as to get a ideal movement status. The result of dynamic analogue of the mechanism is obtained visually. Simultaneously, graph and numeric which reflect the change of motion parameters can be shown.
