Abstract: The dynamic load strength of over-running clutch of dual-turbine torque converter of a loader was analyzed. First, according to the engine speed and the speed ratio of the torque converter under 12 states in one working cycle, the speeds of I-turbine and II-turbine of the torque converter in each state were calculated. Second, based on the speeds, the torques of I-turbine and II-turbine in each state were calculated in CFD. Thus the stress of the roller, inner ring and outer ring of the over-running clutch in different period of time was calculated. Third, the over-running clutch was dynamically analyzed using finite element method, and the instantaneous stress distribution maps of the roller, inner ring and outer ring of the over-running clutch were obtained. Finally, the maximum stress position was given. This study provides a theoretical basis for the structural optimization of over-running clutch.

Key words: fluid transmission and control, finite element method, over-running clutch, CFD, dynamic simulation
