A Comparison of Two Reduction Techniques for Forced Response of Shrouded Blades with Contact Interfsis including flexibility residual attachment modes and free interface modes, but there are significant differences in their implementation. Both methods can be applied to nonlinear forced response analysis of turbine blades with contact interfaces in shroud. In this study, the shroud contact elemen观点 发表于 2025-3-29 15:15:37

Dynamic Substructuring with a Sliding Contact Interface, time-variant interface due to a sliding contact is considered. The contact can be without or with friction. The problem can be tackled in time domain using primal assembly and numerical time integration, and in time-frequency domain using dual assembly, thus obtaining a Time Dependent Frequency Res字谜游戏 发表于 2025-3-29 23:22:36
Introducing SEMM: A Novel Method for Hybrid Modelling,ted by either numerical simulation or direct measurements. The resulting hybrid FRF model is full-rank, consists of the DoF of both input models, and contains a physically relevant weighted mix of input dynamics. It is demonstrated that with SEMM a numerical DoF-set can be used to extend an experime平静生活 发表于 2025-3-30 02:11:39
