Dynamic simulation of cam mechanism of piston-cam engine with counter-position placement

The working theory and characteristic of cam mechanism of piston-cam engine with counter-position placement was introduced. The engine mechanism model was built on UG/Modeling/Assemblies platform. In Scenario for Motion the simulation is made combined with ADAMS. Then the simulation created the curve of displacement,velocity and acceleration of the piston. The curve of simulation was approached to the characteristic of the mechanism motion and the result was mainly satisfied. The combination of CAD and CAE is an effective and reliable optimized design method and make a useful effort to the research of piston-cam engine.
