Global wind energy has developed rapidly in recent years, and the offshore wind turbines
(OWTs) have been applied to much more applications. Because the support structure of an …

This article reports on the physics-based models for the diagnosis (detection, isolation,
localization, and quantification of damages) and prognosis (prediction of the future evolution …

飞机结构安全性设计思想经历了从静强度设计, 安全寿命设计, 损伤容限与耐久性设计到单机
追踪的演变, 未来有进一步向结构数字孪生的方向发展的趋势. 飞机结构数字孪生是数字线程 …

Aircraft are complex engineering systems composed of many interconnected subsystems
with possible uncertainties in their structure. They often function for a long number of flight …

Typical civil infrastructures are prone to fatigue-induced failure due to repeated loading
during their service life. To effectively manage the consequences of fatigue-induced failure …

This paper proposes a linear recursive Bayesian filter for minimum variance unbiased joint
input and state estimation of structural systems. Unlike the augmented Kalman filter (AKF) …

Simultaneous presence of multiple fatigue cracks in the same structural element is a critical
problem affecting system safety. However, initiation and growth of these cracks is affected by …

The precise maintenance and scientific management of large and complex mechanical
equipment are of great significance for ensuring the safe operation of equipment and …

Setting inspection intervals based on an accurate prediction of fatigue crack sizes is
essential for sustaining the integrity of aeronautical structures. However, the fatigue crack …

Accurate remaining useful life (RUL) estimation of rolling bearings can significantly improve
the safety, availability, reliability and productivity of a rotating machinery system. In this …
