摘　　要：为实现对砂型铸造的熔炼过程能量消耗的建模仿真,针对熔炼控制过程具有离散性而能耗过程具有连续性的特点,建立了基于混合Petri网的熔炼过程HPN能耗模型,研究了熔炼工序模型能耗的计算方法。针对某企业的砂型铸造熔炼过程,利用Hypens插件在MATLAB中建立能耗模型,进行计算求解,得到了HPN模型的能耗曲线,并与实际能耗曲线进行了对比分析,验证了模型的有效性。In order to model the energy consumption process of sand casting melting procedure, considering the discreetness of control process and the continuity of energy consumption process, we build an energy consumption model based on hybrid Petri nets and propose a formula to calculate the energy consumption of the model. Then the model is applied to a real melting procedure of an enterprise and we get the energy consumption curve which is compared to the actual curve to prove the validity of the model.
