Modern product design based on integrated simulation technology

In order to predict possibly forthcoming problems in product design, manufacture and application during product design phase. The product design method based on integrated simulation technology was proposed. The architecture of integrated simulation technology was constructed which focused on the product design for discrete manufacture industries. This architecture included the manufacture process simulation layer, application results simulation layer and optimization technology support layer. The manufacture quality could be predicted from the simulation of manufacture process. The operation effect could be got from the simulation of virtual operation. In addition, the product could be optimized based on those simulation results. Meanwhile, the integrated simulation information flow and their transfer characteristics during the design process of new product were analyzed. Finally, one application example of mechanical die-cast products was given in order to demonstrate the usage of integrated simulation technology in new product design.
