The present paper shows the modal dynamic behaviour of a single cone synchronizer mechanism. A 3D finite element model is proposed to calculate the natural frequency of the system. By using an efficient method, the natural frequencies of every single component as well as the full system are extracted under different boundary conditions. The natural frequencies of the system in neutral and engaged conditions are extracted and the effective modes are identified. The finite element model is extended to evaluate transient response of the synchronizer mechanism. The effect of different boundary conditions on the modal response is presented. The results show that changing the actuator position can have a significant effect on the dynamic responses of the system. This methodology can be implemented to examine the transient behaviour of other shifting mechanisms.
