摘要
常规船舶舱室空调通风管路能够完成船舶舱室的通风任务,但受船舶在海水中行驶,时常遭遇不确定性大风影响,管路存在振动频率与噪声较大的不足,为此提出船舶舱室空调通风管路减振降噪方法研究。引入通风管路流体动力学,基于Kip Stephen Thorne振动原理计算,构建减振降噪模型;合理选材提升通风管路材料阻尼性,优化包覆声学材料,实现船舶舱室空调通风管路减振降噪方法的研究。试验数据表明,提出的方法研究较常规方法减振77.24%,降噪81.13%。
Conventional ship cabin air-conditioning ventilation pipe to complete her mission of ship cabin ventilation, but the ship in the sea, often encounter uncertainties winds, pipeline vibration frequency and noise of the larger deficiencies, therefore put forward the ship cabin air-conditioning ventilation piping antivibration noise reduction method research. The fluid dynamics of the ventilation pipeline is introduced, and the vibration and noise reduction model is built based on Kip Stephen Thorne vibration principle. Reasonable selection of material to improve the damping of the ventilation pipeline material, optimize the coating acoustic material, and realize the research on the method of vibration and noise reduction in the air conditioning and ventilation pipeline of the ship's cabin. The experimental data show that the proposed method can reduce the vibration by 77.24% and reduce the noise by 81.13%.
