Abstract
The tensioner of the engine front end accessory drive system was taken as a study object, and the mechanical structure and working principle of the automatic tensioner were analyzed. The hysteresis behavior test of tensioner torque-angular displacement was carried out, and the effects of different excitation frequencies and excitation amplitudes on the hysteresis behavior of the tensioner were analyzed. According to the modified Dahl hysteresis model, the model parameters of the tensioner was identified. Based on the identified model parameters, the hysteresis behavior of the tensioner was calculated, and the calculation model accuracy was verified with the tested results. The influence of the hysteresis curve transition area exponent on the tensioner behavior was studied. The dynamic behavior of the engine front end accessory drive system was simulated using the simulation software. The effects of the hysteresis curve transition area exponent on the dynamic behavior of the engine front end accessory drive system were studied under the slow acceleration and the rapid acceleration. The method proposed herein facilitates the predicting the dynamic hysteresis behavior of the tensioner, which has the certain engineering significance for the design and the development of the tensioner and the engine front end accessory drive system.
