论文摘要
在这项工作的过程中，我们检查了塑料轮廓挤出的过程，其中聚合物熔体的形状在所谓的挤出模中，并通过在下游校准单元中固化为其形状。更确切地说，我们专注于开发数据驱动的减少订单模型（ROM），目的是预测校准单元内挤出的轮廓内的温度分布。在其中，ROM是我们基于预测的过程控制总体目标的第一步，以避免最终产品的不希望的扭曲和损坏。
In course of this work, we examine the process of plastic profile extrusion, where a polymer melt is shaped inside the so-called extrusion die and fixed in its shape by solidification in the downstream calibration unit. More precise, we focus on the development of a data-driven reduced order model (ROM) for the purpose of predicting temperature distributions within the extruded profiles inside the calibration unit. Therein, the ROM functions as a first step to our overall goal of prediction based process control in order to avoid undesired warpage and damages of the final product.
