Abstract 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.

Inconel 718砂带磨削的新型能量分配模型

摘要 分析和建模能量分配对于深入了解本质上是动态的磨削过程具有重要意义。然而，关于砂带磨削中动态能量分配的研究相当匮乏，特别是从综合能量评价的角度来看。在此，我们在传热分析、有限元法和优化算法的基础上，提出了一种新的 Inconel 718 砂带磨削能量分配模型。该模型考虑了不同的研磨力、研磨温度、材料去除率和晶粒中的热量积累。通过迭代的方法，可以获得磨削过程中进入工件、皮带、切屑和环境的动态能量。验证了磨削温度和动态能量分配计算。结果表明，计算温度的最大误差在8.4%以内。进一步分析和讨论了磨削参数、磨削温度和磨粒对砂带磨削能量分配的影响。
