摘要:In order to improve longevity, efficiency and working quality of machinery, taking the six-bar mechanism as example, the velocity fluctuation of six-bar mechanism and its adjustment method are studied. At first, an equivalent dynamic model of six-bar mechanism was established with the vector loop equations and kinematic and dynamic characteristics were analyzed based on the model. Then kinematic and dynamic simulation of six-bar mechanism was carried out with software Matlab. The simulation results reveal the real movement regularity of six-bar mechanism of shaper in the stable operation stage. By comparing the simulation results with theoretical calculation, the validity of this method was verified. Finally, the flywheel which can store and release energy was used to adjust the periodic velocity fluctuation. The simulation results with or without flywheel show that the flywheel is of considerable adjustment effect on periodic velocity fluctuation. The peak value of angular velocity and angular acceleration of equivalent component were decreased by 11.3% and 99.57% respectively, thus to improve movement stability. This method proposed in the paper has universal significance for the general mechanism analysis and design.
