【摘要】 以产品仿真模型及其设计活动为主要控制对象,研究面向数字样机的产品设计信息建模的特点,并建立了支持数字样机设计的集成设计信息模型.将产品设计控制对象抽象为反映产品静态特性和动态特性的信息元及反映产品设计活动的设计元.从产品几何仿真、物理仿真和行为仿真三方面建立数字样机对象信息模型;以设计树对象、设计角色对象和资源配置对象建立设计过程控制信息模型.以此为基础建立面向数字样机的分布式产品协同设计仿真环境.更多还原

【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).更多还原
