车辆动力学仿真软件。-: Railway Vehicle Dynamics Simulation activities include software development and use of simulation software modeling and simulation in two stages. Object-oriented viewpoint and method to re-examine the railway vehicle dynamics simulation modeling and simulation software design needs. Recorded using the Unified Modeling Language UML dynamic simulation modeling, 3D configuration requirements, systems, components, state variable dynamics under the three-tier structure of a computer system, simulation software architecture and an important class of applications and their relationships. Implements a component-based mapping of the 6 DOF Nonlinear railway vehicle dynamics simulation software.
