【摘要】 海洋平台的噪声对平台上人员的影响越来越受到关注,已逐渐成为平台设计时必须重视的指标,但是由于海洋平台结构复杂,振动和噪声源非常繁复,在平台设计阶段准确预估平台上的噪声是非常困难的。本文利用边界元法在已知声源的条件下对某油气钻井平台进行了噪声预估,声源的频谱由制造商提供。计算给出了平台上的声场分布,预估结果为平台上的设备布置提供了参考。更多还原

【Abstract】 The noise on offshore platforms is paid much attention to in recent years and becomes an important design criterion.Because of the complexity of the structure of the platforms and the heavy and comphcated vibration and noise sources,noise prediction on the offshore platforms is almost an impossible mission.In this paper,the noise on an offshore platform under designing is predicted using the boundary element method in which the spectrum data of the noise sources were obtained from the manufacturers.The predicted results show the spacial distribution of the noise and provide sufficient proof to the designers.更多还原
