摘要

根据挤压机部件的几何尺寸和 COMSOL MULTIPHYSICS 软件通过实验确定的低密度聚乙烯的特性，创建了设备的数字模型，并通过流体力学计算了聚合物熔体从挤压机喷嘴流出的流速。实验测得的聚合物流速与模型得出的数值之间的一致性在允许误差范围内。这证明了数字孪生模型的适当性，该模型将用于预测以低密度聚乙烯为基础的复合材料的粘度特性及其在挤压机中通过混合生产的技术状态。

Development of a Digital Twin of the Extruder for Production of Filament from Low Density Polyethylene

On the basis of the characteristics of low-density polyethylene determined experimentally from the geometric dimensions of the extruder parts and COMSOL MULTIPHYSICS software a digital model of the apparatus was created, and the flow rate of the polymer melt from the extruder nozzle was calculated hydrodynamically. The agreement between the experimentally measured polymer flow rate and the value obtained from the model lies within the permissible error. This establishes the adequacy of the digital twin model, which will be used to predict the viscosity characteristics of composite materials based on low-density polyethylene and the technological regimes of their production by blending in the extruder.
