摘要

本文旨在研究土-结构相互作用对台湾西海岸丹麦技术大学10mw参考风力发电机组夹套子结构地震反应的影响。由于台湾位于环太平洋地震带，因此评估风力涡轮机在地震载荷下的性能具有重要意义。基于柔性体积法，建立了海上风力机地基阻尼对整体阻尼的贡献量化有限元模型。结果表明，基础阻尼对海上风力机总阻尼的贡献占临界阻尼的1.28% ~ 1.50%。土-结构相互作用对地震反应有显著影响。

Modeling the Influence of Soil-Structure-Interaction on Seismic Response of Jacket Substructure for the DTU 10MW Offshore Wind Turbine

This paper is intended to study the influence of soil–structure interaction on the seismic response of jacket substructure for the Technical University of Denmark 10-MW reference wind turbine on the west coast of Taiwan. Since Taiwan is located in the circum-Pacific seismic belt, there is significant interest in assessing the behavior of a wind turbine subjected to seismic loading. Based on the flexible volume method, a finite element model was employed to quantify the contribution of foundation damping to overall damping of offshore wind turbines. The results show that foundation damping was estimated to contribute 1.28%–1.50% of critical damping to total offshore wind turbine damping. The soil–structure interaction effects have significant influence on seismic responses.

期刊介绍： The primary aim of the IJOPE is to serve engineers and researchers worldwide by disseminating technical information of permanent interest in the fields of offshore, ocean, polar energy/resources and materials engineering. The IJOPE is the principal periodical of The International Society of Offshore and Polar Engineers (ISOPE), which is very active in the dissemination of technical information and organization of symposia and conferences in these fields throughout the world. Theoretical, experimental and engineering research papers are welcome. Brief reports of research results or outstanding engineering achievements of likely interest to readers will be published in the Technical Notes format.
