本文提出了一种新的热场建模方法，这里称为灵活的划分算法（FDA）预测的机电一体化系统的温度场，其实时应用的热效应有显着的影响，最终产品的性能和可靠性。该算法利用三维空间的灵活划分来处理温度场的空间分布，以物理定律为基础推导出状态空间表示的控制方程，便于对被分析的温度场进行重构和控制。三个数值模型（涉及笛卡尔坐标和圆柱坐标）的说明，以突出FDA的实时建模和计算的有效性和实用性。在薄壁部件加工应用的背景下，FDA进行了数值评估和实验验证。其解决方案与使用商业有限元分析（FEA）软件计算的结果吻合良好，证实了其获得准确结果的能力，但计算时间显着减少，并且在需要实时计算物理场时，其有效性作为FEA的补充。
This paper presents a new thermal-field modeling method referred to here as a flexible division algorithm (FDA) for predicting the temperature fields of a mechatronic system, and its real-time applications where thermal effects have a significant influence on the performance and reliability of the final products. This algorithm, which takes advantages of the flexible division in 3-D space to deal with the spatial distribution of thermal fields, is built upon physical laws to derive the governing equations in state-space representation that facilitates the reconstruction and control of the thermal field being analyzed. Three numerical models (involving both Cartesian and cylindrical coordinates) are illustrated to highlight the effectiveness and usefulness of the FDA for real-time modeling and computing. In the context of a thin-walled component machining application, the FDA is evaluated numerically and validated experimentally. Its solutions agree well with results computed using commercial finite-element analysis (FEA) software, confirming its ability to obtain accurate results, but with significantly less computation time, and its effectiveness as a complement to FEA when real-time computing of a physical field is required.
