In order to reduce the vibration when the comber is in high-speed operation, method of using the linear independent vector, a mathematical analysis was used in the original comber detaching roller transmission mechanism, the Solidworks 3 d modeling technology, Adams virtual prototype technology and MATLAB computer programming technology were used in studying detaching roller transmission mechanism of combing machine, the individual components of inertial force and the proportion in the total inertia force of the mechanism were discussed, and compared the changes of the institutions in the inertial force before and after adding weight. The research results show : the inertial force of timing adjustment plate ,connecting rod 1,eccentric sleeve, swinging arm, connecting rod 2,rocker and rocker connector accounted for the proportion of the total inertia force is respectively 0.73%, 8.01%, 36.87%, 38.55%, 5.72%, 8.75%, 5.72%;the method of adding the weight on the eccentric sleeve can make the total inertia force decrease by 11.30%, improve the speed of combing machine and reduce the consumption of energy.
