The paper analyzes the development of collaborative research platform, summarizes the three common ways of building collaborative research platform, e.g., Web2.0-based collaborative research platform, collaborative research platform based on management process, and collaborative research platform based on document management. Although each common collaborative research platform has its own characteristics, the collaborative support for the core activities of scientific research is insufficient. Then it discusses the concept and types of collaborative research, designs the process of research project management and collaborative research, puts forward the overall architecture of collaborative research platform based on private cloud disk, and designs its function structure. Finally, the realization and application of collaborative research platform is discussed. The collaborative research platform based on private cloud disk will be a good reference for the informationalization of scientific research in universities.
