Abstract: The simulation system of
plasticity processing based on network is presented. This system aims at
combining the network technology with the way of simulation of the
plasticity forming process, because plasticity processing needs to
deliver design data and information quickly via network and use the way
of simulation to optimize the manufacturing technique. The system is
applied to optimize the forging technique
of connecting-rod and crankshaft. The manufacture information and images
are delivered rapidly. The processing technique is optimized by means of
physical simulation; The phenomena of material flowing and filling
behavior within the mould are analyzed. At the same time some important
parameters such as deforming stress and side-shifting stress are determined. Some conclusions can uncover the principles of disfigurement in forging, and can be used to program appropriate forging technique and to design reasonable mould structure. The practice proves that the simulation system of plasticity processing based on network is feasible and valuable.
