Vibro impacts induced by backlash between meshing gears lead to excessive vibration and noise in many geared rotating systems. For illustration purposes, a five-speed manual transmission of a front wheel automobile is examined, with focus on the neutral gear rattle problem. Several non-linear and linear mathematical models of generic physical systems are developed to understand, quantify and control the problem. A few rattle criteria have been proposed and their application has been demonstrated. Design guidelines for reduced rattle are discussed, and the roles played by the clutch, flywheel and drag torque have been investigated. Results are consistent with those reported in the literature.
