AI Technical Summary

Technical Problem

In existing technologies, the cycle and cost of full-scale ship testing are too high, and the error of scaled-down model testing is large, making it difficult to accurately study the hydrodynamic noise of ships.

Method used

Design a full-scale acoustic test and evaluation system for a cooling circulating water system. The test bench is installed above the circulating water tank, with the inlet of the cooling circulating water system completely submerged in the tank. Turbulent pulsating pressure and self-noise are detected by deploying pulsating pressure sensors and hydrophones, and acoustic test and evaluation are carried out in conjunction with a data analysis system.

Benefits of technology

It achieves high-accuracy acoustic test evaluation in real-scale scenarios, reduces measurement errors, improves the safety and operability of the test, and the data is closer to the actual ship conditions.

Abstract

本申请公开了一种实尺度冷却循环水系统的声学试验评估系统,涉及船舶技术领域,该系统利用试验台架承载实尺度冷却循环水系统的管路结构,将其入水口处的导流罩完全浸没在循环水槽的试验段中、出水口连通循环水槽,并在导流罩的内流道的壁面布设有若干个脉动压力传感器用于检测内壁湍流脉动压力,在管路结构的预定检测位置处的内流道的壁面布设有若干个水听器用于检测自噪声,从而可以在实尺度场景下完成声学试验评估,相比于缩比模型试验的方法准确度较高,更贴近实船数据,且易于实现。
