| 中文摘要: |
| 汽车室内噪声影响乘坐舒适性，齿轮音是汽车噪声的一种重要形式，开展齿轮音研究对降低汽车室内噪声具有重要价值。本文分析了齿轮噪声产生机理，指出轮齿的非理想啮合是产生齿轮噪声的主要原因。阐述了齿轮噪声试验原理及测量方法，采用DS2000数据分析系统分析某自动变速箱在测试台架环境下各挡位的阶次噪声水平，可作为分析齿轮噪声的一种有效方法，为降低自动变速箱齿轮噪声指明改善方向。 |
| 英文摘要: |
| The vehicle noise inside the car affects the experience of riding comfort and gear noise is an important form of vehicle noise. Therefore, research on gear noise is of great value to reduce vehicle noise. The mechanism of gear noise is analyzed and the non-ideal meshing of gear is the main cause of gear noise. The principle and measuring method of test are described. The order noise level of different gear position of the automated transmission under the test bench environment is analyzed using DS2000 data analysis system. It is an effective method to analyze the gear noise and can be used to point out the improvement direction for reducing the gear noise of automated transmission. |
