| 摘 要： | 定量分析了高压纯水射流喷射噪声A声压级与射流压力、压力脉动及射流靶距的联系,主要得出了喷射噪声在常见条件下随着压力脉动的减小反而略有增加的结论。因为压力脉动减小导致流速增加,从而使冲击噪声和涡流噪声略有增加。

| Abstract: | The paper quantitatively analyses the relation between A sound pressure grade of the high pressure pure water jet injection and jet injection pressure,pressure pulse,the target distance,and mainly educes that the jet injection noise doesn't reduce when the pressure pulse reduces.Because velocity of flow reduces when the pressure pulse reduces,the noise of impulsion and the noise of vortex increase a little. |

| Keywords: | jet injection noise pressure pulse reduce noise |
