| 中文摘要: |
| 研究气缸通过气动阀的瞬态排气过程所产生的脉冲性冲击噪声及其噪声控制方法。重点介绍了气缸排气噪声的产生机理和时频域辐射规律,通过分析排气噪声声源特性、辐射噪声预测理论、噪声控制理论和方法等方面的国内外研究现状,指出了气缸排气噪声控制所亟需解决的关键技术问题。 |
| 英文摘要: |
| The impuse noise generated by the cylinder transient exhaust through valves and noise control were summarized. Focuses on the pneumatic exhaust noise generation mechnism and time-frequency radiated properties, the current research staus of exhaust acouatic source characteristic, radiated noise prediction and noise control theory and methods were introduced. Then, some proposals for further research on pneumatic exhasut noise control were presented in detail. |
