Abstract�� To control the various simulation models and design activities, the features of information modeling of virtual prototyping design were discussed, and an integrated information model was proposed. Product design object was abstracted as property unit of static and dynamic characters and operating unit. Virtual prototyping information model was expressed from product geometry, physics and behavior. Design process information model was formalized with the control of design tree object, design role object and resource configuration object. This information model was used successfully in the construction of distributed collaborative simulation environment (DCSE).
