Simulation Analysis of Friction Disc Temperature Field of Hydro-Viscous Variable Speed Clutch

Abstract

Hydro-viscous variable speed clutch transmits torque by means of viscous fluid between the friction discs. The study of temperature distribution on friction disc plays a very important role for the design of hydro-viscous soft-start device. When the grooves on the driving friction disc surface have more complex shape, the analytic solution of the temperature field is difficult to obtain. By the advantage of the periodicity of geometric dimension along the circumferential direction of the driving friction disc, physical model with radial and annular groove is simplified and built. FLUENT software is used to make a simulation analysis on the temperature field of the friction disc, transient and steady state temperature distribution is obtained which provides a new approach to the analysis of the temperature field of the friction disc with complex grooves.
