Based on the results of the forward research project, the main objective of this project is an interactive concept for selecting and designing hypocycloidal polygonal shaft-hub-connections under torsional and/or bending loading. This is a basic requirement for the practical use of polygonal shaft-hub-connections. The design concept has to take the influences of dimensional and form deviation as a result of manufacturing into consideration. The experimental results provide the required notch effect and the permissible torque load. In addition, the test results are used for calibration of the calculations of slip, strain and stress. A new standardisation is planned based on all results and testing time of the new concept for selecting and designing polygonal shaft-hub-connections . This should replace the actual German standard DIN 32711.Due to the increasing complexity of the components, the calculation of fatigue strength is given to an assessment using local stresses. This is based on the large geometric variety of the polygonal connections. To realize an assessment using local stresses, a possible calculation model or stress hypothesis should be selected and tested.

基于前瞻性研究项目的结果，该项目的主要目标是在扭转和/或弯曲载荷下选择和设计内摆线多边形轴毂连接的交互概念。这是实际使用多边形轴毂连接的基本要求。设计理念必须考虑制造造成的尺寸和形状偏差的影响。实验结果提供了所需的缺口效应和允许的扭矩负载。此外，测试结果还用于校准滑移、应变和应力的计算。根据选择和设计多边形轴毂连接的新概念的所有结果和测试时间，计划制定新的标准化。这应该取代实际的德国标准 DIN 32711。由于部件的复杂性不断增加，疲劳强度的计算改为使用局部应力进行评估。这是基于多边形连接的大量几何变化。为了实现使用局部应力的评估，应选择并测试可能的计算模型或应力假设。
