Outline
In order to analyze the performance of the shifting system and design the parameters of the shifting system parts, the transmission model of shift execution system has been established, and combined with Trapezoidal Back-EMF and square wave control principle of Brushless Direct Current (BLDC) motor, Simulink control model of motor module is established. ADAMS is used to import physical parameteric model, the interactive simulation of motor model and mechanical system is realized through ADAMS interface. Drum fixed torque loading simulation and motor three-ring control principle are applied to analyze system response characteristic and process parameters of the dynamic shifting process. Simulation and test results show that motor torque loading process impacts remarkably system function realization, parts shifting forces and shifting duration. Selecting appropriate parameters of control system and strategy could realize shift process control.
