New Bayesian calibration method fuses heterogeneous data for dynamic systems

This paper introduces a novel multi-level Bayesian calibration method designed to fuse information from various sources and account for uncertainties in dynamic multi-component systems. The approach quantifies uncertainty at both component and system levels, enabling corrected model predictions. It processes heterogeneous data sequentially through an iterative strategy, applicable in both offline and real-time online calibration scenarios. The effectiveness of this methodology is demonstrated using thermo-mechanical behavior analysis of gas turbine engine rotor blades. AI

IMPACT This research could improve the accuracy of complex system modeling and prediction in engineering applications.
