The modelling, simulation and analysis of a synchroniser mechanism as a component of wet Dual Clutch Transmissions (DCT) is presented in this paper. Mechanism engagement is demonstrated using rigid body models with a detailed drag torque model, to establish its variation over the process. Dimensionless equivalent cone and chamfer torques are used to study the impact of drag torque from a design perspective, and parameter studies performed to verify this method. Outcomes suggest the high dependency of speed synchronisation on both cone angle and friction coefficient, while the chamfer torque are highly dependent on chamfer angle, but not friction coefficient.
