【摘要】：随着工程机械行业竞争的不断加剧，产品交付周期越来越短，复杂程度和质量要求越来越高，研发周期、设计成本、市场响应速度成为企业生存新的三大决定因素。企业跨地域一体化发展，跨地域办公、跨地域同步设计、异地制造已经成为常态，身处不同地域的团队之间的设计协作比以往任何时候都更为重要。突破传统的设计模式，应用协同设计技术，打造一个系统化、规范化的协同设计平台，探索一条适合于企业自身特点的协同研发之路已经成为企业的必然选择。产品全生命周期管理系统（PLM：Product Lifecycle Management)作为支持并行协同设计的信息技术，为协同设计平台搭建提供了系统支持。数字化、参数化的CAx软件产品的成熟应用为异地协同设计的数据传递提供了稳定、可控的定制化平台。计算机技术、信息技术及相关机械设计理论、标准的诞生与发展为搭建协同设计平台提供了便利。借助数字样机及可视化技术，项目组实现了产品全生命周期的数据管理与协同。设计人员可以在虚拟环境中模拟挖掘机各种工况，，进行试验与验证；可以随时按照优化建议或者市场、用户需求进行设计更改与优化，直至满足需求。挖掘机被誉为“工程机械之王”，产品结构特殊，装配关系复杂，是涉及多行业、多领域的技术、资金密集型工程机械设备。产品研制需要多单位、多部门协作配合、同步设计才能顺利完成。项目组人员结构复杂，各专业间知识冲突大，进度协同难度大，频繁的工作协调和信息数据传递增加了设计风险，这些共同导致了产品研制周期长、成本高、市场响应速度慢。文章基于挖掘机进行了协同设计研究与分析，研讨了协同设计的信息建模方法及工作流程控制技术，建立了挖掘机全生命周期管理的信息系统，搭建了异地协同设计的信息共享、流程管理、产品数据管理与项目管理平台，实现了多部门紧密联动的协同设计机制，为缩短研发周期、降低设计成本、提升市场响应速度提供了可能。
[Abstract]:With the increasing competition in the engineering machinery industry , the product delivery cycle is becoming shorter , the complexity and the quality of the products are becoming more and more high , the R & D period , the design cost and the market response speed become the three decisive factors for the survival of the enterprise . The enterprise cross - region integration development , the trans - regional office , the trans - regional synchronous design , the off - site manufacturing has become the norm , and the design cooperation among the teams in different regions is more important than ever before .

Breaking through the traditional design pattern , applying the collaborative design technology , creating a systematic and standardized collaborative design platform , exploring a collaborative R & D road suitable for the enterprise ' s own characteristics has become the inevitable choice of the enterprise .

As the information technology supporting concurrent collaborative design , the product lifecycle management system provides the system support for collaborative design platform . The mature application of digital and parameterized CAx software product provides a stable and controllable customization platform for data transfer of collaborative design .

Computer technology , information technology and related mechanical design theory , the birth and development of the standard provide the convenience for building the collaborative design platform . With the aid of digital prototype and visualization technology , the project team realized the data management and collaboration of the whole life cycle of the product . The designer can simulate various working conditions of the excavator in the virtual environment for testing and verification ;
The design changes and optimization can be made at any time in accordance with the optimization recommendations or market and user requirements until the requirements are met .

The excavator is known as the " king of engineering machinery " , the product structure is special , the assembly relation is complex , it is a multi - industry , multi - field technology , capital - intensive engineering machinery equipment . Product development needs multi - unit , multi - department cooperation coordination , synchronous design can be completed successfully . The project team has complex structure , large knowledge conflict among disciplines , great difficulty in progress , frequent work coordination and information data transfer increase design risk , which leads to the long period of product development , high cost and slow market response speed .

Based on the research and analysis of the collaborative design of the excavator , the information modeling method and the workflow control technology of the collaborative design are discussed , the information sharing , process management , product data management and project management platform of the collaborative design of the excavator are built , and the collaborative design mechanism of the multi - sector close linkage is realized , which provides the possibility for shortening the R & D period , reducing the design cost and improving the market response speed .
