| description | The saddle-shaped buckling deformation is the main thermal buckling deformation mode of the friction pairs in the hydro-viscous clutch. The equivalent model of contact deformation is established to obtain the contact and temperature field distribution characteristics of the deformed friction pairs， which are based on the hertz point contact theory of the ellipsoid and buckling deformation law. The distribution and variation of deformed friction pairs contact stress under the soft-start condition are obtained. A two-dimensional transient temperature field calculation model that considers the time-varying characteristics of the contact stress distribution and the convective heat transfer conditions are proposed， and the temperature rise in surface along with the temperature field of friction pairs in the sliding process is simulated and analyzed. The results show that in the process of soft-start， the friction pairs develop from the local contact to full contact. The contact area develops from the bending ellipse symmetrically distributed on both sides of the friction pair to full coverage and shows that the stress decreases from the contact center to the surrounding in an elliptical gradient. Under the influence of the contact stress， the temperature field of the sliding friction also decreases in an elliptical gradient from the high-temperature center to the surrounding. The difference in convective heat transfer conditions causes the high-temperature center to shift towards the outside of the sheet disk relative to the contact center， which increases the overall temperature of the outer diameter side. The results lay a theoretical ground for further research on the thermo mechanical coupling characteristics and the torque thermal instability of the hydro-viscous friction pairs. |
