Dynamic response analysis of a moored crane-ship with a flexible boom
Abstract:The dynamic response of moored crane-ship is studied. Governing equations for the dynamic response of a crane-ship coupled with the pendulum motion of the payload are derived based on Lagranges equations. The boom is modeled based on finite element method, while the payload is modeled as a planar pendulum of point mass. The dynamic response was studied using numerical method. The calculation results show that the large-amplitude responses occur at wave periods near the natural period of the payload. Load swing angle is smaller for crane-ship with flexible boom, in comparison with rigid boom. The ship surge motions have large vibrations for crane-ship with flexible boom, which were not observed for a rigid boom. The an alysis identifies the significance of key parameters and reveals how the system design can be adjusted to avoid critical conditions. 作者: Author: Hui-li REN Xue-lin WANG Yu-jin HU Cheng-gang LI 作者单位: School of Mechanical Science and Engineering, Huazhong University of Science and Technology, Wuhan 430074, China 期 刊: 浙江大学学报A(英文版) ISTICEISCI Journal: JOURNAL OF ZHEJIANG UNIVERSITY SCIENCE A 年,卷(期): 2008, 9(1) 分类号: U615.35 Keywords: Dynamic response Moored crane-ship Finite element method Rigid-flexible coupling dynamic model 机标分类号: TP3 R85 机标关键词: dynamic response finite element method numerical method system design 基金项目: 国家自然科学基金,教育部高等学校博士学科点专项科研基金【Dynamic response analysis of a moore】相关文章:
