本发明涉及船舶振动噪声技术领域,具体地说,涉及基于宽频线谱实时分析的船舶振动噪声预分析系统。其包括共振噪声分析单元,共振噪声分析单元用于对其他船舶撞击暗礁引发当前船舶设备产生的共振噪声进行分析,生成船舶设备高噪声区域,共振噪声分析单元的输出端连接有噪声辐射方向定位单元,噪声辐射方向定位单元的输出端连接有噪声源方向反馈单元。本发明通过分析海域内船舶撞击暗礁出现的噪声引发当前船舶设备产生的共振噪声情况,确定该船舶撞击暗礁的位置,避免后续行驶的船舶再次撞击暗礁。

    The invention relates to the technical field of ship vibration noise, in particular to a ship vibration noise pre-analysis system based on broadband line spectrum real-time analysis. The system comprises a resonance noise analysis unit, the resonance noise analysis unit is used for analyzing resonance noise generated by current ship equipment due to the fact that other ships impact a submerged reef, a high-noise area of the ship equipment is generated, and the output end of the resonance noise analysis unit is connected with a noise radiation direction positioning unit. The output end of the noise radiation direction positioning unit is connected with a noise source direction feedback unit. According to the method, the resonance noise condition generated by the current ship equipment caused by the noise generated when the ship collides with the submerged reef in the sea area is analyzed, the position of the ship colliding with the submerged reef is determined, and the follow-up ship is prevented from colliding with the submerged reef again.
