Abstract:
In order to solve the contradiction between the impact of vehicle and the high temperature caused by the engagement process of motor grader clutch, a dynamics model of engagement process of big differential speed ratio clutch was established with ADAMS software, and the law of the loading speed and the magnitude of hydraulic oil impacting on the acceleration and the slipped friction power was studied by this model. To improve the performance of clutch engagement, based on the designing acceleration of the graders, in order to minimize the slipped friction power, two phase loading strategy was proposed, and the buffer phase was divided into a fast-loading phase and a slow-loading phase, to provide the reference for the designing of the graders. The results show that the slipped friction power decreases with the increase of the loading speed of the hydraulic oil, but the acceleration increases with the increase of the loading speed. The slipped friction power decreases with the increase of the pressure of the movement of engagement, but the acceleration increases with the increase of the pressure. The reliability of the model and the feasibility of the proposed control strategy are verified. 3 tabs, 12 figs, 14 refs.
