Abstract:

Torsion characteristics of DMF-CS were the effects of the torsional stiffness combined with the system damping, which sophisticatedly explained the vibration isolation and damping characteristics of DMF-CS. With the simulation of the torsion characteristics of DMF-CS, the torsional hysteresis curves were plotted under different friction coefficients. The simulation results show that the hysteresis area increases with the friction coefficients, and the hysteresis curves are framed by the curve without friction force. According to the above results, the hysteresis torsion characteristics model of DMF-CS was established. The torsion characteristics experiments of DMF-CS were completed, and using the experimental data, the model parameters were identified. From comparison, the identification model is close to the experimental one, which validates the reliability of the established model.
