Modelling of the thermo-elastic behavior of an externally driven spindle system (T01#)

目前，补偿主轴系统热弹性行为的方法需要大量的参数化工作。因此，拟议的转移项目旨在减少当前外部驱动主轴系统的参数化实验工作量。这是通过基于子项目的预测模型对项目的补偿模型进行参数化来实现的。预测模型的参数化只需要知道轴承在不同工作点的摩擦力矩，在主轴轴承试验台上就可以快速有效地确定摩擦力矩。这些实验确定的值对于采用相同类型轴承的主轴系统普遍有效。因此，不再需要对物理主轴系统进行详细的实验研究。项目第一阶段开发的建模和补偿方法的工业适用性证明是通过与ChIron Werke GmbH&Co.kg合作在外部驱动的主轴上进行的拟议转移项目进行的。

Currently, the methods for compensation of the thermo-elastic behavior of main spindle systems require significant parameterization effort. Therefore, the proposed transfer project aims for a reduction of the current experimental effort for parameterization of externally driven spindle systems. This is achieved by performing the parameterization of the compensation model of the project based on the prediction model of the sub-project. Parameterization of the prediction model only requires the knowledge of friction moment of the bearings at different operating points, which can be determined quickly and efficiently on spindle bearing test rigs. These experimentally determined values are universally valid for spindle systems employing bearings of the same type. Elaborate experimental investigations on physical spindle systems are thus not longer required. The proof of suitability for industrial application of the approaches for modelling and compensation developed in the first phase of the project is conducted with-in the proposed transfer project in collaboration with Chiron Werke GmbH & Co. KG on an externally driven spindle.
