摘要

在汽车变速器下线台架上根据齿轮振动传递路径理论选择两个振动测量位置,同时测量两个位置20台变速器的啮合振动。在整车上测量各档位啮合阶次噪声及其振动,并进行啸叫声的主观评价。通过下线台架的振动、整车上变速器各档位齿轮啮合阶次的噪声和振动三者间的相关性分析,确定了台架上最佳的测量位置和啸叫声可接受时的振幅临界值。该研究可以正确、有效地识别变速器的啸叫及其振动特性。

Abstract

Selecting two measurement positions on the EOL of vehicle transmissions according to the transfer paths theory of gear vibration, the mesh vibration of the two positions of 20 transmissions were measured on the test rig. The noises and vibration of the speeds mesh orders were measured on vehicles. The subjective evaluation of gear whine was also done by professional NVH engineers. According to the correlations of vibration of EOL, noises and vibration of gear mesh orders on vehicles, the optimum measurement position on EOL and the vibration amplitude critical values of acceptable gear whine on vehicles were determined by using the strong correlations results. This research can identify the gear whine and vibration characteristics of transmissions correctly and effectively.
