Visual running simulation of railway vehicles based on Simulink and VRML

It was a complex kinematical procedure that railway vehicles ran on the truck. After analysis on running characteristics and simulation approaches of railway vehicles, the data production process of basic motion control was presented for railway vehicle model. Though 3-D modeling technique and VRML modeling language, the virtual models and running scene of railway vehicles were constructed. The motion control and simulation of the railway vehicle models were achieved by Simulink. A vehicles were constructed. The motion control and simulation of the railway vehicle models were achieved by Simulink. A visual running simulation platform of railway vehicles was developed, and the running simulation was realistic on the platform.
