慢慢地，越来越多的电动汽车进入消费市场。为了生产具有成本效益的电机，一流的质量和足够的数量，了解缠绕过程是必不可少的。导线行为的预测是线圈缠绕的关键挑战之一。因此，建立了详细的模型，以调查在线性缠绕过程中的线行为。基于有限元的仿真工具ANSYS ANSYS ®用作静态结构部件工具。为了在该仿真中表示缠绕的高动态过程，必须进行一些初步调整。这意味着，忽略了动态影响，例如线圈体的旋转速度或加速度。在静态结构分析中，将给定的边界条件应用于模型。通过拉伸试验和测试表的值验证了受审查的金属丝的材料特性。为了实现最佳收敛，针对每个单独的接触行为选择不同的接触算法。此外，需要对网格进行特定调整以获得显著结果。线圈绕线的最新技术是一种实验性的工艺，它提供了良好的工艺参数，从而提供了绕线技术的专业知识。然而，有很多不同的相互作用的参数，必须根据边界条件进行优化。缠绕过程的仿真模型，其中变化的参数可以优化有关的最佳缠绕结果，呼吁在该领域的广泛研究。生成的模型使用户不仅可以影响工艺参数，还可以修改缠绕体的几何形状。为了使模拟具有科学性，还通过实验进行了验证。
Slowly but steadily, more and more electrical vehicles push onto the consumer market. To produce electrical engines cost efficient, in first-class quality and in sufficient quantity, it is indispensable to understand the process of winding. The prediction of the wire behaviour is one of the key challenges of coil winding. Therefore, a detailed model is built to investigate the wire behaviour during the linear winding process. The finite element based simulation tool ANSYS Workbench® serves as the static structural component tool. To represent the high dynamic process of winding within this simulation, some first adaptions have to be made. This means, that dynamic influences such as rotational speed or acceleration of the coil body are neglected. Within the static structural analysis, the given boundary conditions are applied to the model. The material properties of the wire under scrutiny are validated by a tensile test and by the values of the datasheets. In order to achieve the best convergence, different contact algorithms are selected for each individual contact behaviour. Furthermore, specific adjustments to the mesh are necessary to gain significant results. State of the art in coil winding is an experimental procedure, which delivers good process parameters and, thus, expertise in winding technology. However, there are a lot of different, interacting parameters, which have to be optimized in terms of boundary conditions. The simulation model of the winding process, where varying parameters can be optimized pertaining to the optimal winding result, calls for extensive research in the field. The generated model enables the user not only to influence the process parameters but also to modify the geometry of the winding body. To make the simulation scientifically sound, it is validated by experiments.
