| Abstract: | By using transmission modeling and simulated EASY5 software,a dynamic power shifting system model of automatic transmission was created.This dynamic model employs the technology of several other power-train component models as well as several component inertias and shaft stiffness.During the process,the changes of torque in out shaft are discussed and the dynamic equations during shifting are established.The simulation results from the model are shown and the methods for improvement of shifting quality are put forward. |
