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.

基于远期研究项目的结果，该项目的主要目的是用于选择和设计扭转和/或弯曲负载下的型多层多边形轴枢纽连接的交互式概念。这是多边形轴枢纽连接实际使用的基本要求。由于制造业的考虑，设计概念必须采取维度和形式偏差的影响。实验结果提供了所需的缺口效应和允许的扭矩负载。此外，测试结果用于校准滑动，应变和应力的计算。根据所有结果和测试时间的测试时间，用于选择和设计多边形轴枢纽连接的新标准化。这应该取代实际的德国标准DIN 32711。这是基于多边形连接的大几何变化。为了使用局部应力来实现评估，应选择和测试可能的计算模型或应力假设。
