Dynamics Modeling of Heavy Special Driving Simulator

摘要

Based on the dynamical characteristic parameters of the real vehicle,the modeling approach and procedure of dynamics of vehicles are expatiated. The layout of vehicle dynamics is proposed,and the sub-models of the diesel engine,drivetrain system and vehicle multi-body dynamics are introduced. Finally,the running characteristic data of the virtual and real vehicles are compared,which shows that the dynamics model is similar closely to the real vehicle system.
