Research on Key Techniques of Visual Simulation of Automobile Engine Based on Virtual Reality Technology

According to the deficiency of real-time and interaction in current visual simulation of automobile engine, a visual simulation of automobile engine was proposed based on Virtual Reality (VR). Firstly, focusing on four-stroke and reciprocating-piston automobile engine, the mathematical model of crank-connecting rod was established, and then that of valve train was obtained by the result data of ADAMS in dynamics simulation. At the same time, the visual model of hierarchical data was set up based on Creator, and local coordinate systems of linkage on motion mechanisms were defined by DOF technology. In addition, the visual simulation program was implemented with Vega Prime and Visual Studio. NET 2003. At last, the test shows that the system performs distinctively in interaction and real-time.
