| Abstract: | In this article,piston CAD/CAM technology and the state of the art were introduced.On the basis of three dimensional FEM analysis,adopting object oriented technique and expert knowledge type's database,the solid model of piston could be established.After the creation of FEM meshes and the establishment of boundary conditions,through stress,hydraulics,contact and deformation analyses,the design of piston could be optimized.Finally,the optimized object went through the NC program which is automatically developed in the computer.Piston CAD/CAM technology was a complete system developed on the basis of three dimensional solid model. |
