Abstract:This paper discussed the research status and development for the dynamical problem of automotive gear rattle. It made a review from those five aspects of the mechanism of gear rattle, solution to mathematical modeling, objective evaluation method of gear rattle, experiment and data processing of gear rattle, and solution to gear rattle. Based on the analysis of the problems and defects in the study of gear rattle, some research suggestions for the study of automotive transmission gear rattle in the future was proposed in this paper from those points of simulation model improvement, testing program effectiveness and objective evaluation method rationalization and so on.
