Abstract

Linear winding is one of several process alternatives in coil production. Due to its simplicity and robustness, it is used in various applications. At the Institute for Factory Automation and Production Systems at the Friedrich-Alexander- University Erlangen-Nuremberg, simulation tools are used to validate and evaluate various winding process alternatives. In this context, this paper describes a finite element (FE) analysis of the linear winding process. First, an overview of the linear winding technique and its special features is given. The configuration of the FE simulation model and the applied material model is presented in detail and necessary simplifications are described. After executing the simulation, the simulation results are validated against the experimental data. The validated simulation is used to identify significant influencing variables. Based on the simulation, it can be deduced that an increase of the wire tensile force as well as a reduction of the wire diameter in the tolerance window leads to a smaller overall circumference of the coil. Furthermore, the caster angle could be determined as an influence on the coil diameter.

基于显式有限元法的线性缠绕过程数字孪生

线性绕组是线圈生产的几种替代工艺之一。由于其简单性和健壮性，它被用于各种应用程序中。在弗里德里希-亚历山大-埃尔兰根-纽伦堡大学的工厂自动化和生产系统研究所，仿真工具用于验证和评估各种缠绕工艺方案。在此背景下，本文对直线缠绕过程进行了有限元分析。首先，概述了线性缠绕技术及其特点。详细介绍了有限元模拟模型和应用材料模型的结构，并进行了必要的简化。仿真完成后，将仿真结果与实验数据进行了对比验证。验证后的仿真用于识别重要的影响变量。仿真结果表明，增大导线的拉伸力，减小公差窗口内的导线直径，会导致线圈的总周长变小。此外，可以确定脚轮角度对线圈直径的影响。
