This device makes sure that the rotational velocity of transmission gear equals to that of synchronizer sleeve after the synchronization process in order to smooth the process of engagement, and avoid the abnormal impact from different rotational velocity during engaging. Since the development of MT as well as AMT, using manual transmission gearbox, gradually mature recently, a high transmission efficiency, high shifting capability, and low cost of synchronizer is necessary. The thesis presents dynamic analysis and simulation on synchronizer, which is used to avoid the abnormal impact between different gear ratio during shifting on manual transmission gearbox. Because the complicated mechanism and random engagement of synchronizer are all shrouded in a short time, it is difficult to realize the synchronization process by experiment. Using ADAMS, the entire shifting process and two minor phase modules, separated from entire shift process, are all constructed for realizing synchronized action and random mesh between sleeve and clutch gear. After verifying results from the simulation model, Taguchi method was used by the thesis to optimize the performance of synchronization. Consequently, the results on this thesis can help to not only understand synchronization process but also provide for improving two major demands on manual transmission gearbox, which are vehicle operational comfort and lifespan of synchronizer.

碩士 === 國立交通大學 === 機械工程系所 === 93 === The synchronizer is mainly used to avoid the abnormal impact during shifting for manual transmission (MT) and automated manual transmission (AMT) system. This device makes sure that the rotational velocity of transmission gear equals to that of synchronizer sleeve after the synchronization process in order to smooth the process of engagement, and avoid the abnormal impact from different rotational velocity during engaging. Since the development of MT as well as AMT, using manual transmission gearbox, gradually mature recently, a high transmission efficiency, high shifting capability, and low cost of synchronizer is necessary.
The thesis presents dynamic analysis and simulation on synchronizer, which is used to avoid the abnormal impact between different gear ratio during shifting on manual transmission gearbox. Because the complicated mechanism and random engagement of synchronizer are all shrouded in a short time, it is difficult to realize the synchronization process by experiment. Using ADAMS, the entire shifting process and two minor phase modules, separated from entire shift process, are all constructed for realizing synchronized action and random mesh between sleeve and clutch gear. After verifying results from the simulation model, Taguchi method was used by the thesis to optimize the performance of synchronization. Consequently, the results on this thesis can help to not only understand synchronization process but also provide for improving two major demands on manual transmission gearbox, which are vehicle operational comfort and lifespan of synchronizer.
