Data-based lifetime prediction for a function-oriented induction hardening process. (T06*)

该项目的目的是在面向功能的生产意义上，通过反转工艺特征和局部疲劳强度计算，对给定疲劳强度的轴的感应淬火工艺参数进行预测。将与工业合作伙伴一起使用样本组件对该方法进行评估。传递项目为旋转对称部件的纯热处理开发了工艺特征，并使用计算的局部强度和三维应力张量来计算最薄弱环节模型的疲劳强度。这些计算参数是通过各种初始状态下的实验研究和感应硬化状态下的旋转弯曲试验来确定的。

The aim of the project is to predict the process parameters of an induction hardening process for a given fatigue strength of shafts in the sense of a function-oriented production by inverting the process signature and the local fatigue strength calculation. The method will be evaluated using a sample component together with the industrial partner. The transfer project develops process signatures for the purely thermal processing of rotationally symmetrical components and uses the calculated local strengths and three-dimensional stress tensors to calculate the fatigue strength with the weakest-link model. The parameters for these calculations are determined by experimental investigations in various initial states and rotary bending tests in the induction-hardened state.
