典型风浪作用下基于分布式弹簧边界的海上风机耦合响应机理
The coupling mechanisms of offshore wind turbines with distributed spring boundaries under typical winds and waves
摘要
Abstract
Because of offshore wind turbine fully coupling calculation software FAST V8 can not simulate pile soil interaction,the updated FAST V8 is introduced by distributed linear spring boundary constraint condition and the coupled motion equation of substructure is derived.A coupled numerical simulation model of rotor-nacelle-hub-tower-pile foundation structure with distributed linear spring boundary condition is established.The dynamic characteristics of the base fixed boundary and distributed linear coupled spring boundary model under the combined action of wind and wave are analyzed.The results show that the time history and frequency domain responses of the tower top displacement and the base bending moment change significantly,especially for the second-order frequency of the structure.At the same time,it can be observed that the distribution spring boundary constraint condition has a more obvious effect on low wind speeds,while the fixed boundary constraint condition model has a more significant effect on high wind speeds.关键词
