- The automatic 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 dynamic 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 tensioner were analyzed. Based on the modified Dahl hysteresis model, the identification method of tensioner model parameters and method of hysteresis behavior in the stick and slip process were proposed. Based on the established model and the identified model parameters, the hysteresis behavior of the tensioner were calculated, and the calculation model accuracy was verified with the test results. The influence of the hysteresis curve transition area exponent on the automatic tensioner behavior was studied. The dynamic behaviors of the engine front end accessory drive system were simulated using Simdrive 3D. The effects of the hysteresis curve transition area exponent on the dynamic behaviors of the engine front end accessory drive system were studied under slow acceleration and rapid acceleration. The method proposed herein facilitates the predicting the dynamic hysteresis behavior of the automatic tensioner, which has certain engineering significance for the design and development of tensioners and the engine front end accessory drive system.
