Carbon fiber and glass fiber mixed design and structural performance analysis for large wind turbine blade by FAN Shijie, MIAO Weipao, LI Chun, WANG Haisheng, ZHU Haibo, YUE Minnan

“…Carbon fiber is increasingly used to replace conventional glass fiber in layup designs of large wind turbine blades to improve their structural strength, but the high cost of carbon fibers makes it difficult to cover the entire area of the blade.Therefore，the research of the influence of mixing ratio and relative position of carbon fibers and glass fibers on the structural performance of the blade can help to obtain higher performance and lower cost wind turbine blades.The proportion of carbon fibers and glass fibers in the corresponding position of the main beam of the blade and the relative position of layup were adjusted by Ansys software.And the structural statics, modal and buckling analyses were conducted by using a combination of computational fluid dynamic method and finite element method.The results show that the performance of the blade main beam using carbon fibers and glass fibers mixed layer can be similar to that of carbon fiber blades.When the carbon fibers near the tip of the blade can improve the blade first-order modal and buckling factors. …”

Analytic Solutions for the Stationary Seismic Response of Three-Dimensional Structures with a Tuned Mass-Inerter Damper and Bracket by Lin Deng, Cong Yao, Xinguang Ge

“…Finally, four numerical examples are presented to investigate the following: (1) verification of the proposed response solutions, showing that the calculation time of the proposed method is approximately 1/500 of that of the traditional method; (2) examination of spatial effects in 3D structures under unidirectional excitation, revealing that structural seismic responses in the direction along the earthquake ground motion is approximately 10⁴ times that in the direction perpendicular to the ground motion; (3) investigation of the spatial dynamic characteristics of a 3D structure subjected to unidirectional seismic excitation, showing that the bracket parameters significantly affect the damping effects on an EDS; and (4) application of the optimization method for the damper’s parameters that considers system dynamic reliability and different weights of the damper’s parameters as constraints, indicating that the most economical damping parameters can achieve a reduction in displacement spectral moments by 30–50%. …”
