Abstract
A transient temperature-stress coupled analysis is performed to investigate the thermomechanical coupled analysis of multidisc friction pairs in Hydro-viscous drive under simulated operation conditions. The normal pressure on all the surfaces are obtained from the principle of force equilibrium and then the heat flux acting on the related surface are also deduced. Based on the finite element method, the 3-D transient thermal and thermomechanical models of single pair are established as the typical one. The distribution of thermal and thermomechanical behavior during the soft-start can be studied. The results show that the maximum temperature occurs at the center of each subregion, where hot spots can be observed. The minimum hoop stress distribution can be observed in the separator disk.
