摘　　要：随着海上风机的快速发展,其带来的水下噪声对海洋生态环境的影响受到了广泛关注.目前对于海上风机水下噪声的研究主要以测量为主,采用Virtual Lab软件进行数值模拟能够快速预测海上风机带来的水下噪声.研究发现,5 MW海上风机水下噪声的峰值频率主要分布在低频段,风荷载也会在一定程度上增大水下噪声.With the rapid development of offshore wind turbine,the impact of its underwater noise on marine ecological environment attracts widely concern.At present,the research on underwater noise of offshore wind turbine mainly focuses on measurement.Software Virtual Lab is used to conduct numerical simulation,which can quickly predict underwater noise brought by offshore wind turbine.The research shows that the peak frequency of the underwater noise of 5 MW offshore wind turbine mainly distributes in low frequency range,and the wind load can increase the underwater noise to some extent.
