| Popis: | Analyzing and modelling energy partition is of great significance to provide an in-depth understanding of the grinding process that is essentially dynamic. However, research on dynamic energy partition in belt grinding is rather scarce, especially from the perspective of a comprehensive energy evaluation. Here, we propose a novel energy partition model for belt grinding of Inconel 718, on basis of heat transfer analysis, finite element method and optimization algorithm. The model takes into account varying grinding force, grinding temperature, material removal rate and the heat accumulation in grains. Through an iterative approach, the dynamic energy entering the workpiece, belt, chips and ambient during grinding process can be obtained. Grinding temperature and dynamic energy partition calculation are validated. Results show that the maximum error of the calculated temperature is within 8.4 %. Further, effects of grinding parameters, grinding temperature and abrasive grains on belt grinding energy partition are analyzed and discussed in detail. |
