The knotter is the core component of the rectangular bale baler. In view of the short service life, low reliability, and easy fracture during the working process, this paper takes the D-knotter’s winding rope system as the research object, lumped mass method and Lagrangain method were adopted to set up dynamic model and equations of winding rope system, Built a dynamic simulation block diagram. The dynamic response analysis of the winding rope system verified the accuracy of the dynamic differential equation and determined the fatigue analysis method. The Six Sigma reliability analysis module was used to analyze the reliability of the winding rope system, the reliability of the winding rope system at different rotational speeds was calculated, putted forward some optimizing measures for fatigue life of winding rope system, the result indicated that the fatigue life of winding rope system after optimization were greatly improved.
