Summary:

To reduce the idling rattle of manual transmissions, the computer simulation has been utilized. However, the conventional simulation model could not express properly the relationship between the transmission oil temperature and the rattle noise level, especially in case of transmission with backlash eliminator in constant mesh gears. In this study, the authors carried out detail experiments investigating the motion of each part in the transmission. Based on the experimental results, an additional mass representing all constant mesh speed gears supported on plain or rolling element bearings was introduced to the simulation model. Using the improved model, it was confirmed that the calculated RMS value of the fluctuation in countershaft angular acceleration corresponds to the experimental rattle noise level
