Development of Gear Rattle Analytical Simulation Methodology 951317

This paper gives an overview of the analytical and experimental activities undertaken to develop an OEM vehicle system design tool for minimizing transmission gear rattle. Detailed analytical investigations were performed to develop an understanding of the important gear rattle parameters. Specialized test techniques were developed and implemented to gain an understanding of the key element of gear impacting. Results of the analytical and experimental studies were used to develop a simulation code which contains the elements required to accurately simulate gear rattle while providing greater efficiency and ease of use as compared to commercially available simulation codes.
