An Improved Dynamic Model Updating Method for Multistage Gearbox Based on Surrogate Model and Sensitivity Analysis

Huachao Xu, Datong Qin, Changzhao Liu, Yang Zhang
2021 IEEE Access  
This proves the effectiveness of the improved updating method. INDEX TERMS Gear, gearbox, dynamic model, updating method, sensitivity analysis, surrogate model.  ...  Model updating can improve the accuracy of the multistage gearbox dynamic model (MGDM).  ...  Hence, based on a surrogate model and sensitivity analysis, an improved dynamic model iterative updating method is proposed herein.  ...

Turbine design development for pressure gain combustion engines

Majid Asli, Technische Universität Berlin, Christian Oliver Paschereit, Panagiotis Stathopoulos
2022
The pulsating character and highly unsteady exhaust of PGCs are so deteriorative for such a turbine and will spoil the whole efficiency gain expected from a PGC-driven gas turbine.  ...  However, plenty of challenges needs to be solved for a reliable and efficient implementation of PGCs in gas turbine cycles.  ...  Additionally, Norddeutscher Verbund für Hoch-und Höchstleistungsrechnen (HLRN) is acknowledged for providing the high performance computing resources.  ...
