Dynamical Behavior and Strength of Structural Elements with Regeneration Induced Imperfections and Residual Stresses (B04)

在子项目中，研究了再生过程对循环加载部件振动幅值和寿命的随机影响。特别地，分析了特定路径再生引起的散射和容差。第三个资助期的目标是考虑到这种差异，优化虚拟路径内的修复。在此背景下，利用稳健和基于可靠性的优化策略，得到了对维修参数的建议。因此，结构-机械优化为再生路径的选择提供了支持，并为整机的再生提供了重要参数。

Within the sub-project the stochastic influences of regeneration processes on the vibration amplitudes and lifetime of cyclic loaded components are investigated. In particular, the path-specific regeneration-induced scattering and tolerances are analyzed. The aim of the third funding period is the optimization of the repair within the virtual path considering this variances. In this context, recommendations are derived for the repair parameters using robust and reliability-based optimization strategies. The structural-mechanical optimization therefore supports the selection of regeneration paths, and provides important parameters for the regeneration of the whole engine.
