英文摘要：

In order to quickly respond to customer requirements and realize the optimization design of weft insertion mechanism in high rapier looms development, a new method about solution of kinematics equation was developed. The kinematics equation was proposed, and the kinematic curve of displacement, velocity and acceleration were given. The kinematics spectrum of this weft insertion mechanism was also provided according to these parameters. An optimization design of the conjugate cam weft insertion mechanism was established based on kinematics spectrum with dynamics condi- tions. As a case, the optimization solution expansion of a rocker was also presented. Results based on MATLAB demonstrate the rightness of the proposed method.
