国产轿车变速器啸叫噪声源的识别与控制
Identification and Reduction of Gear Whine Noise of Domestic Transmission
摘要
Abstract
Gear whine in automotive transmission was identified and reduced. The whine noise was tested in vehicle and in the NVH testbench. Through order tracking analysis and noise contribution a- nalysis, the whine orders were found. The problem was special that different parts have the same or- der. Then through the tooth contact spot analysis the source of the gear whine was found. Combined with the position and the shape of the contact pattern, the helical modification was made. The whine noise drops by 5dB（A）.关键词
