| Abstract: | A kind of pneumatic system and drive shift mechanism of automated mechanical transmission(AMT)system for heavy-truck was introduced based on the design requests of the drive shift mechanism.The dynamic mathematical model of the drive shift mechanism was established based on pneumatic principle.The dynamic model of this mechanism was built by MATLAB / SIMULINK software.The variety of pressure and stroke of intake/exhaust chamber was simulated under different air pressures. |
