| 摘 要： | To study the vehicle dynamic characteristics under typical cycle conditions, a steadystate simulation model of the engine in GTPower is established and verified with engine bench test data. A dynamic model of the engine is then established. A cosimulation with the engine dynamic model in GT-Power and the vehicle transmission model in AMESim is conducted based on the technology of HLA/RTI. The parameter changes of vehicle powertrain in the accelerating process of 0-32km/h, and vehicle typical cycle conditions are studied. The influence laws of the typical parameters influencing vehicle dynamic characteristics are obtained, and a new approach of improving vehicle dynamic characteristics is proposed. The results show that the vehicle powertrain dynamic model can simulate, analyze and predict dynamic changes of vehicle in actual operating conditions and guide powertrain matching and optimization.

| Abstract: | To study the vehicle dynamic characteristics under typical cycle conditions, a steady-state simulation model of the engine in GT-Power is established and verified with engine bench test data. A dynamic model of the engine is then established. A co-simulation with the engine dynamic model in GT-Power and the vehicle transmission model in AMESim is conducted based on the technology of HLA/RTI. The parameter changes of vehicle powertrain in the accelerating process of 0-32.km/h, and vehicle typical cycle conditions are studied. The influence laws of the typical parameters influencing vehicle dynamic characteristics are obtained, and a new approach of improving vehicle dynamic characteristics is proposed. The results show that the vehicle powertrain dynamic model can simulate, analyze and predict dynamic changes of vehicle in actual operating conditions and guide powertrain matching and optimization. |
