Analysis of Stick-slip Induced Abnormal Click Noise at Transmission Output End and the Corresponding Improvement Measures
摘要
Abstract
Through the investigation and analysis of an automobile"clicking"abnormal noise in starting process, it is determined that this noise is induced by the stick-slip vibration at the joint between the inner surface of the transmission shaft end and the coupling end of the gearbox. According to the contact theory and the actual structure characters, the possibility of stick-slip occurrence is calculated and a simplified physical model for analyzing the stick-slip motion is established. The influencing factors associated with the click noise are discussed and some measures for controlling the click noise are put forward. Finally, by reducing the dynamic friction coefficient at the joint via inserting a special washer into the contact interface, the problem of click noise in the starting process is solved. Since there are very few research results about the slick-slip of transmission systems, this work has significant guideline to avoid the similar problem during the design process of vehicles.关键词
