A real-time hybrid testing strategy for offshore wind turbines under wind–wave–earthquake loads using a frequency-decoupled wind load simulator

Yingpeng Tian, Ying Xu, Junfan Zuo, Lingfeng Xiao et autres

The expansion of offshore wind turbines into deep-sea environments necessitates rigorous testing under combined wind, wave, and earthquake loads. Real-Time Hybrid Testing(RTHT) offers an effective approach for evaluating these multi-hazard interactions. To address the Froude-Reynolds scaling conflict inherent in conventional physical modeling, …

Isolation, purification, structural characterisation, and in vitro bioactivities of raspberry (Rubus idaeus L.) polysaccharides

Yingpeng Tian, Jie Chen, Lei Wang, Feng Xue et autres

Abstract This study explored the characterisation of polysaccharide fractions from raspberry (Rubus idaeus L.) and evaluated their biological activities in vitro. Raspberry polysaccharides (RAPs) were extracted using a complex enzymatic method and subsequently separated via a DEAE-Sepharose fast-flow column, resulting in two …

Evaluation of control accuracy for a boundary-coordinating device in a real-time hybrid test

Yingpeng Tian, Quanwang Li, Changcan Bu, Fenglei Fan et autres

Multi-axial real-time hybrid simulation (ma-RTHS) utilizes multiple loading devices to realize boundary control with multiple degrees of freedom (MDOF), thus being capable of handling complex dynamic scenarios and multi-dimensional problems. In this paper, a new control technique was developed by using a …

Large‐scale hybrid test of a curved bridge considering complete boundary condition by a large spatial loading system

Yingpeng Tian, Jie Chen, Chunbo Du, Dan Xu et autres

Abstract Small‐radius curved bridges are mostly used for overpass ramps, that are spatially irregular and usually have very complex seismic behavior. It is not easy to reproduce such behavior because of the need for large‐scale shaking tables. The hybrid test is one …

Shaking‐table substructure test using a MDOF boundary‐coordinating device

Yingpeng Tian, Tao Wang, Huimeng Zhou, Chunbo Du

Abstract Boundary coordination is necessary for a shaking‐table substructure test (STST), which includes transferring forces and displacements between the tested and numerical substructures. Unlike other real‐time hybrid tests (RTHTs), the physical substructure is mounted on a shaking table and excited by the …

Reproduction of seismic responses of wind turbine tower by hybrid tests considering shear and bending coupled boundary control

Yingpeng Tian, Tao Wang, Huimeng Zhou

The dynamic responses of wind turbine towers subjected to earthquakes and winds are very complex and might cause significant damages. However, the reproduction of the dynamic response in a laboratory is not easy because the specimen shall be scaled very small to …

Recursive Predictive Optimal Control Algorithm for Real-Time Hybrid Simulation of Vehicle–Bridge Coupling System

Huimeng Zhou, Bo Zhang, Xiaoyun Shao, Yingpeng Tian et autres

Real-time hybrid simulation (RTHS) is recently applied to study the vibration of the vehicle–bridge coupling system, where bridges and the vehicle are the numerical and experimental substructures respectively. Inevitable time delay of the boundary loading imposed to the experimental substructure will greatly …
