摘要

摘要: 极地科考破冰船在开展大洋和两极科学考察时, 一方面如常规科考船一样需尽量控制自身的辐射噪声, 以确保不影响探测设备的功能; 另外一方面要求尽量减少自身辐射噪声对海洋和两极生物生存发展的影响。然而尤其是高等级破冰强度的极地科考破冰船, 其所具备的特殊船型、大功率主机、高强度螺旋桨以及可能安装于船体外的全方位推进器都会给水下辐射噪声控制带来了极大的挑战。文中介绍了某极地科考破冰船项目水下辐射噪声的前期研究。首先比较了船舶水下辐射噪声相关标准, 分析了船舶水下辐射噪声的来源, 归纳总结了抑制水下辐射噪声的方法。然后针对某极地科考破冰船的水下辐射噪声进行了实船验证, 实测中采用多水听器方法, 将测得的辐射噪声数据与国外同类船进行对比, 初步分析了目前极地科考破冰船水下噪声特性。研究结果可为开展极地科考破冰船水下辐射噪声抑制研究提供理论参考。

Abstract: For the polar icebreaking research vessel with high icebreaking capacity, the control of the underwater radiated noise(URN) will be a great challenge because of its special ship-type, high-power main engine, high-strength propeller and optional 360° azimuth propulsion unit out of ship hull. In this paper, the previous research on URN of a polar icebreaking research vessel is introduced. The related standards of URN of vessels are compared, the sources of URN are analyzed, and the methods for suppressing URN are summarized. Then, the URN of the polar icebreaking research vessel is tested, in which the multi-hydrophone method is used for measuring the radiated noise. The measured URN data are compared with that of similar foreign vessels, and the URN characteristics of the polar icebreaking research vessel are analyzed. This research may provide a reference for the research of URN suppression for polar icebreaking research vessel
