“…Wojciech Homik et al [3] established a thermal fluid dynamics analysis model of the engine torsional vibration damper, determined the optimal operating temperature range of the damper, and conducted experimental verification. Savaia et al [4] proposed a method to estimate the temperature of the magnetorheological damper using the thermodynamic relationship between circuit resistance and magnetorheological fluid temperature. Wang [5] investigated the relationship between silicone oil damper heating and torsional vibration amplitude and damper equivalent damping coefficient using silicone oil as a viscous and viscoelastic material, respectively.…”

High temperatures in torsional vibration dampers can cause silicone oil to fail, increasing crankshaft vibration and shortening component fatigue life. Accurate prediction of the damper temperature field is key to the manufacture of highly reliable torsional vibration dampers. This study establishes the relationship between temperature, torsional vibration amplitude, silicone oil viscosity, rotational speed, housing and inertia ring clearance, and heat generation power based on Comsol. A bench test was carried out on a 6-cylinder inline diesel engine. The simulated temperature profile matched the tested result in terms of trend and relative value, and the established model could accurately predict the temperature field of the engine crankshaft torsional vibration damper.

“…[33] investigated the impacts of magnetic hysteresis and noted that there was negligible increase at values of yield stress and no change at viscosity. Some recent studies [34][35][36][37] on the relationship between MR damper and temperature have taken place in the literature. However, none of these coincide with the contribution presented in this study.…”

Accurate control of the magnetorheological damper (MRD) damping force and current is necessary to realize the effective semi-active suspension control. However, the temperature sensitivity of the magnetorheological fluid makes the MRD force strongly dependent on temperature changes, leading to the problem of the model mismatch and degradation of control effect. In this paper, the experimental study of MRD at different currents and velocities from −40 °C to 80 °C was implemented. It reveals the characteristic of MRD damping loss at low temperatures and viscous damping reduction at high temperatures. On this basis, a new parametrized hyperbolic hysteresis model with temperature as an independent variable is proposed, providing an accurate description of the viscosity, stiffness, and hysteresis characteristics of the MRD. A simplified temperature-revised inverse model is proposed to calculate the driving current with demanding force. It could improve the accuracy of driving current by 12.79% and demanding force by 18.67%. A process in the loop simulation is implemented to validate the inverse model with a modified non-chattering algorithm. Together with the inverse model, the proposed algorithm could realize continuous current change, reducing the RMS of acceleration by 14% on road of class B. Furthermore, the temperature compensation could improve the control effect by 19.78%.
