Simulation Module of Crank Rocker Mechanism Based on GTENG Engine

Abstract

GTENG engine technology is a complete set of real-time 3D engine that is mainly applied to the simulation field of engineering equipment. Crank rocker mechanism is common in engineering equipment. This paper analysed the evolution of crank slider mechanism, and two motion types and parameter compute of crank rocker mechanism. The design of CCrankRocker, associated mesh scene node and using coordinate system all were discussed. Further, compute way of motion simulation of the four components required for CCrankRocker was emphasized. The paper indicated that is needs set firm parent-child relationship between bar and slider when modeling in 3DS MAX, and enumerated some legends of the origin of each node and the directing of axis in coordinate system of crank rocker mechanism. Finally, the use of crank rocker mechanism module was illustrated by analysing the main function of Load function correlating model nodes with classes, and the motion simulation example of bucket rocker mechanism was given with partial program. The application shows that the simulation of crank rocker mechanism based on GTENG engine is smooth, practical and wide.
