Simulation of powertrain and dynamics of automobile based on SimulationX

A physical model using network modeling method, which aims at the dynamic matching between the newly developed 8-speed automatic transmission (8AT) and the target car, was introduced based on the SimulationX software platform. The modeling method and key technologies were presented through the modeling process of the drive train, including engine, torque converter and automatic transmission. After matched to 8AT, the simulation result shows that the maximum speed of the target car could reach 225km/h and the acceleration time from 0 to 100 km/h is 9.5 seconds. In addition, the precision of the modeling and simulating were confirmed by comparison with test results.
