【摘要】 随着桥式起重机市场的发展，客户需求正朝着多样化、个性化、短周期、高效率的方向发展。在短时间内能够快速响应市场的需求成为了企业赢得市场的重要条件。快速响应设计作为缩短起重机研发周期、提高产品研发能力的先进技术，已成为起重机设计与制造的研究热点之一。桥式起重机桥架是典型的系列化产品，新产品的设计大多是对已有设计的基础上进行修改、借用与创新。因此，实现桥式起重机桥架快速响应设计，设计知识继承与重用是关键。为解决该问题，引入动态全息产品模型的思想，将设计知识以信息形式集成于全息产品模型上，并使其“动态”地作用于设计过程。以动态全息产品模型为基础进行桥式起重机桥架快速响应设计系统研究与开发。首先从全生命周期出发，针对设计各阶段的不同需求与相互影响，在产品概念设计阶段，利用零装配（Zero D）产品设计方法将传统的设计模型抽象化为通用产品信息模型，将产品设计知识以信息的形式集成于模型上，并动态更新，驱动产品进入详细设计。通过对动态全息产品模型建立方法的研究，最终建立桥架动态全息产品模型及模型库。然后对桥式起重机桥架快速响应设计关键技术研究进行深入研究，进行桥架的模块划分与模块组合；建立基于设计数据的实例库，提出桥架的混合推理设计方法，实现知识的重用推理与再利用；研究桥架的知识重用设计方法，实现桥架的快速响应设计。最后，在上述研究基础上，通过参数设置、模型驱动、工程图调整、工艺信息统计、有限元分析、数据管理及借用等主要功能模块的研究，建立基于动态全息产品模型的桥式起重机桥架快速响应设计系统。通过在某企业的实际应用与验证，该系统实现了桥式起重机桥架快速响应设计，效果良好，缩短了桥架设计周期、提高了知识重用率和设计效率。更多还原

【Abstract】 With the development of the bridge crane market, the direction of customer demand is toward diversification, personalization, short cycle, high efficiency. Responding quickly to market demand in a short time has became the precondition for enterprise to gain a larger share of the market. As advanced technology of shortening the development cycle crane and improving the product development ability, Rapid response design has become one of hot topics of the crane design and manufacturing.Overhead crane bridge is a typical series product, and the design of new products is commonly be modified, borrowed, and innovated based on existing designs. Therefore, design knowledge inheritance and reuse is the key to realize rapid response design of overhead crane bridge. In order to solve the problem, text introduced into the conception of dynamic holographic product model, which integrate design knowledge in holographic products model in the form of information, and take effect dynamically in the design process.First, based on total life cycle, according to the different needs and interaction, the traditional design model is abstracted into a common product information model with Zero D, in concept design phase. And design knowledge is integrated in the product model in the form of information, updated dynamically, and the product is drived to the detailed design. With the reseach of the method for establishing dynamic holographic product model, dynamic holographic product model and model libraries of overhead crane bridge are established. Second, with depth study for key technology of overhead crane bridge Rapid Response Design, bridge modules are classified and combined. And with data based design instance library, hybrid reasoning method is projected to realize knowledge reasoning and reuse. According study for bridge knowledge reuse design method, bridge Rapid Response Design is realized.Finally, on the basis of the above studies, through the study for the main function modules which contain the parameter setting, model driven, engineering drawing adjustment, technology information statistics, finite element analysis, data management and borrowed, overhead crane bridge rapid response design system which is based on dynamic holographic product model is established.Through the practical application and verification in an enterprise, the system realized overhead crane bridge rapid response design, which received good effect，shortened the bridge design cycle, improved the knowledge reusing rate and the design efficiency.更多还原
