Abstract
Due to the apparent heat generation and the observed multiple thermal effects in the long-term operation of belt drive system, the thermo-mechanical coupled analysis for the flexible multi-body system is necessitated. A previously proposed absolute nodal coordinate formulation solid-beam element is adopted to create its thermal integrated counterpart since its deformation modes are appropriate for capturing the deformation of V-belt geometry. By means of the unified description of the temperature field and displacement field, the analysis for heat transfer and the continuum mechanics could be integrated in the V-belt drive system. The heat generation caused by frictional creep and the hysteresis loss due to the material viscosity, as well as the thermal deformation, are all included in the model. By describing the flange of pulley groove using a parameterized revolving segment centered by the pulley axis, the contact between V-belt and the flange of pulley groove could be implemented efficiently without complex 3D geometric description of the pulley. The contact force is calculated using penalty method, and the frictional force is determined by the Coulomb friction law in integral form. Numerical results demonstrate the feasibility of the proposed analysis method.
