Due tocomputational inefficiency, traditional engineering simulation software and optimization methods areinadequate to analyze optimization problems in VPD. Optimization method based on simulationmetamodel for virtual product development is proposed to satisfy the needs of complex optimaldesigns driven by VPD. This method extends the current design of experiments (DOE) by variousmetamodeling technologies. Simulation metamodels are built to approximate detailed simulation codes,so as to provide link between optimization and simulation, or serve as a bridge for simulationsoftware integration among different domains. An example of optimal design for composite materialstructure is used to demonstrate the newly introduced method.展开更多

The system architecture of virtual product development with KBE has been built and the key technique has been studied to support the system. Knowledge driven method has been put forward based on the traditional theory as a new method of virtual product development. An applied case is presented by taking moving cone assembly as an example to illustrate the process of knowledge driven method in detail. This concludes virtual product development integrated with KBE is feasible to raise the design efficiency and promote the sharing of information and knowledge.展开更多
