Review:Recent Developments in Dynamic Load Identification for Aerospace Vehicles Considering Multi-source Uncertainties
摘要
Abstract
The determination of the dynamic load is one of the indispensable technologies for structure design and health monitoring for aerospace vehicles. However,it is a significant challenge to measure the external excitation directly. By contrast,the technique of dynamic load identification based on the dynamic model and the response information is a feasible access to obtain the dynamic load indirectly. Furthermore,there are multi-source uncertainties which cannot be neglected for complex systems in the load identification process,especially for aerospace vehicles. In this paper,recent developments in the dynamic load identification field for aerospace vehicles considering multi-source uncertainties are reviewed, including the deterministic dynamic load identification and uncertain dynamic load identification. The inversion methods with different principles of concentrated and distributed loads, and the quantification and propagation analysis for multi-source uncertainties are discussed. Eventually,several possibilities remaining to be explored are illustrated in brief.关键词
