针对覆盖件斜楔模具在设计过程中存在的设计周期长、效率低和难以快速响应客户需求的问题,本文提出了一种基于配置的覆盖件斜楔模具变型设计方法。在分析覆盖件斜楔模具典型结构的基础上,以吊装式斜楔模具为例论证了斜楔模具产品配置设计的可行性。给出了基于产品族的斜楔模具产品配置设计的方法,论述了建立配置模板的具体流程。基于配置模板,给出了斜楔模具产品进行变型设计的关键技术。最后结合企业实际应用,以UG为平台,开发了一个基于配置的覆盖件斜楔模具变型设计模块,给出了具体的应用实例。 相似文献

汽车覆盖件模具的设计水平决定了汽车覆盖件的质量,并影响着汽车的性能与外观.本研究在分析拉延模结构设计特点的基础上,提出一种汽车覆盖件数字化设计制造的思路和方法.现有的汽车覆盖件冲压成形工艺设计一般采用经验与计算机相结合的设计方珐,这在某种程度上满足了企业生产的需要,但其设计周期长、效率低、设计质量难于保证.为适应汽车工业的快速发展和市场竞争要求,在汽车模具生产中采用该方法综合利用逆向工程软件、CAD/CAM软件、材料成型分析软件和加工仿真软件的有效组合和数据集成,有效地解决了汽车覆盖件拉延模具快速设计与制造的过程.综合实例表明.该过程可以快速提高模具类产品的研制周期,提高产品的质量. 相似文献

The rapid expansion of enterprises makes product collaborative design (PCD) a critical issue under the distributed heterogeneous environment, but as the collaborative task of large-scale network becomes more complicated, neither unified task decomposition and allocation methodology nor Agent-based network management platform can satisfy the increasing demands. In this paper, to meet requirements of PCD for distributed product development, a collaborative design mechanism based on the thought of modularity and the Agent technology is presented. First, the top-down 4-tier process model based on task-oriented modular and Agent is constructed for PCD after analyzing the mapping relationships between requirements and functions in the collaborative design. Second, on basis of sub-task decomposition for PCD based on a mixed method, the mathematic model of task-oriented modular based on multi-objective optimization is established to maximize the module cohesion degree and minimize the module coupling degree, while considering the module executable degree as a restriction. The mathematic model is optimized and simulated by the modified PSO, and the decomposed modules are obtained. Finally, the Agent structure model for collaborative design is put forward, and the optimism matching Agents are selected by using similarity algorithm to implement different task-modules by the integrated reasoning and decision-making mechanism with the behavioral model of collaborative design Agents. With the results of experimental studies for automobile collaborative design, the feasibility and efficiency of this methodology of task-oriented modular and Agent-based collaborative design in the distributed heterogeneous environment are verified. On this basis, an integrative automobile collaborative R&D platform is developed. This research provides an effective platform for automobile manufacturing enterprises to achieve PCD, and helps to promote product numeralization collaborative R&D and management development. 相似文献

Early stage,
multi-return loop feedback system is a new design and manufacturing concept. It is used in
developing rapid mold manufacturing system based on rapid prototypes. The numerated
manufacturing of RP technology is also used for this system. In order to understand the
characteristics of this system, concepts of forming energy field, forming boundary and
error chain are established and introduced in RP research. The rapid manufacturing of the
dies of automobile deck parts is the best example for applying this new system. 相似文献
