摘要
风机在运行过程中,由于受到环境外激励和风轮转动激励的作用,塔筒会产生振动,甚至会引起共振,影响风机寿命。本文利用北京东方所的DASP数据采集与分析系统,采用OMA方式对某风机进行了模态测试,获得了该风机塔筒的前5阶模态参数,为风机结构的动力学分析和结构优化设计提供了科学依据。
When the wind turbine is operating, the tower is vibrating due to the incentives from wind and rotor. It may cause resonance of the wind turbine and shorten the wind turbine lifetime. In this paper, the author did the wind turbine OMA modal test by China Oriental DASP test system. After the analysis, the author got the first five modal parameters of the wind turbine tower. The study provides a scientific basis for the wind turbine structural dynamics analysis and structure optimization design.
