The Finie Element Analysis and Experimental Study of Temperature Distribution on Powerful Belt Surface Grinding

This paper widly analyses the calculating methods for grinding temperature, By applying the finite element and the advantage of finite difference in time recurrence ,we study two-dimensional nonsteady grinding temperature field and propose a calculating equation for the temperature with high theoretical and practical value. The corresponding computer program is designed to calculate the temperature field for differentcutting parameters, and the results are compared with experiment results. We apply thePeklenik temperature measurement method and an advanced computer sample system tosample data. The experiment results show that the theoretical calculation data are quiteconsistent with experimental data, and some important conclusions are given.
