Abstract: Team working and collaboration is involved in product development process.Collaboration technology is key in realizing product development process management.Through analyzing product developent collaboration working character，a collaboration model for product development is put forward consisting of client view，security control，whole character and network.The key application technology is studied.The application and verification of the model is done in the developed product information integration and sharing platform and solve the problem of large-size nuclear steam turbine collaboration development and paperless application.

Key words: collaboration work, environment model, process management, edition management

摘要： 产品开发过程是多人参与协作的设计过程，协同技术是实现产品开发过程管理的一个关键技术。通过分析产品开发协同工作的特点，提出一种由用户视图层、安全控制层、全局特征层以及网络层所组成的产品开发协同工作环境模型，研究了实施的关键技术，并在所开发的产品信息集成共享平台中获得应用验证，较好解决了大型核电汽轮机协同开发与无纸化应用问题。
