Exact Solution for the Time-Dependent Temperature Field in Dry Grinding : Application to Segmental Wheels

الملخص EN

We present a closed analytical solution for the time evolution of the temperature field in dry grinding for any time-dependent friction profile between the grinding wheel and the workpiece.

We base our solution in the framework of the Samara-Valencia model Skuratov et al., 2007, solving the integral equation posed for the case of dry grinding.

We apply our solution to segmental wheels that produce an intermittent friction over the workpiece surface.

For the same grinding parameters, we plot the temperature fields of up- and downgrinding, showing that they are quite different from each other.
