The transmission system is a vital component that significantly affects a vehicle's performance, power, and fuel efficiency. As vehicle technologies advance, demands on transmission systems continue to increase, with performance often evaluated through gear efficiency, noise levels, and the comfort of gear shifts. Among the key parameters for transmission system performance, synchronization time plays a crucial role. While previous studies have proposed mathematical and computational models of synchronization processes validated by experimental data, limited work has employed GT-Suite software. This article models a gear shift mechanism in GT-Suite to explore the synchronization process phases and analyze parameters influencing synchronization time. The study examines structural and tribological design parameters, evaluating their individual and collective impact on synchronization time. The results demonstrate the influence of varying parameters on the synchronization process, identifying critical phases where each parameter has the most significant effect. These findings provide valuable insights into optimizing synchronization mechanisms and reducing gear-shifting time. Future work may focus on expanding the parameter range and integrating experimental validation to enhance the model's applicability further.
