【摘要】：CAD(计算机辅助设计)技术的应用在制造业中起着重要作用，，是现代企业在市场激烈竞争中获胜的关键技术之一。随着计算机技术的飞速发展，网络环境下的C A D技术已经日渐成熟。基于网络的协同设计，使设计者相互之间突破地理位置的限制，达到了设计信息的交流与共享。随着企业信息化的呼声愈来愈高，许多企业也建立起了相应的CAD软件平台，并应用CAD软件进行产品的设计和分析，取得了明显的效果。但现有的CAD软件没有针对特定的设计对象和对设计信息的交流与共享提出解决方案，对设计人员提高产品的效率和质量有一定的影响。因此，建立一个既能共享信息又能协作设计的开发环境已经成为现代产品设计研究的一个重要方面。本文在讨论了网络化的协同设计技术和现代CAD技术的基础上，结合汽车起重机设计的实际需求建立了网络化的汽车起重机协同设计系统。该系统以.NET为平台，在后台数据库的支持下，为协同设计用户提供在线设计、网络三维建模、在线实时交流和资源共享等服务，系统把这些服务以网页的形式集成和封装成不同的子系统，用户可以通过超链接来访问不同的子系统。系统以汽车起重机伸缩臂为例开发了其参数化设计子系统，该子系统将计算过程封装为页面处理程序，用户输入关键参数后自动计算出伸缩臂的其他参数；本系统根据三维软件SolidWorks提供的API函数，用VB.NET语言在.NET环境下对其进行二次开发，把对伸缩臂的各个部件的开发程序封装成不同的网络应用程序，协同设计用户只需要在网页中输入各个部件对应的关键参数，服务器就可以根据用户输入的信息调用三维造型软件进行网络环境下的三维建模；本文在对汽车起重机伸缩臂零部件进行分析后，建立了汽车起重机零部件三维模型库，服务器可以对零部件的综合信息进行有效的管理。本文根据协同设计技术的交流性和共享性特点，充分结合协同设计工具，将其与本系统有效的集成，进而实现协同设计用户之间、协同设计用户与服务器间的信息交流与共享。文中以汽车起重机的伸缩臂的协同设计为例，验证了系统设计方案的正确性和可行性。
[Abstract]:The application of CAD (computer aided Design) technology plays an important role in the manufacturing industry and is one of the key technologies for modern enterprises to win in the fierce market competition. With the rapid development of computer technology. The technology of C A D in network environment has matured day by day. Collaborative design based on network makes designers break through the limitation of geographical location. The exchange and sharing of design information has been achieved. With the increasing demand of enterprise informatization, many enterprises have also established the corresponding CAD software platform, and used CAD software to design and analyze the products. But the existing CAD software does not provide solutions for specific design objects and the exchange and sharing of design information. It has a certain influence on designers to improve the efficiency and quality of products. Therefore, it has become an important aspect of modern product design research to establish a development environment that can share information and design collaboratively. This paper discusses the cooperative design technology based on network and modern CAD technology. A networked collaborative design system for truck cranes is established based on .NET platform and with the support of background database, which provides online design for collaborative design users in combination with the actual requirements of the design of truck cranes. Web 3D modeling, online real-time communication and resource sharing services, the system integrates and encapsulates these services in the form of web pages into different subsystems. Users can access different subsystems through hyperlinks. The system takes the telescopic boom of truck crane as an example to develop its parameterized design subsystem which encapsulates the calculation process into a page processing program. The other parameters of the telescopic arm are automatically calculated after the key parameters are input by the user. According to the API function provided by 3D software SolidWorks, the system is redeveloped in .NET environment with VB.NET language. The development program of each component of the telescopic arm is encapsulated into different network applications, and the cooperative design user only needs to input the corresponding key parameters of each component in the web page. The server can call the 3D modeling software according to the information input by the user to carry on the 3D modeling under the network environment; After analyzing the parts of the telescopic jib of the automobile crane, a 3D model base of the parts of the crane is established in this paper. The server can effectively manage the comprehensive information of the parts. According to the communication and sharing characteristics of collaborative design technology, this paper fully integrates the collaborative design tools with the system, and then realizes the collaborative design between users. This paper takes the collaborative design of the telescopic boom of the truck crane as an example to verify the correctness and feasibility of the system design scheme.
