In December 2019, Jiuzhou Yunjian's PDM product data management system was commissioned and officially launched.
PDM system, the English name is (Product Data Management). The focus of the PDM system is on product data management in the research and development process. It is the foundation and expansion of digital research and development. Its management categories include: documents, two-dimensional drawings, three-dimensional models, and testing. And simulation data, product technical status, serialized product structure and configuration, work flow, organizational structure and permissions, and core data and mechanisms related to the enterprise.
So what is the significance of the PDM system for commercial aerospace companies? Why spend energy on implementing the PDM system during the intense product design and development process?
At present, commercial aerospace companies generally carry out product development and technical iterations based on 3D digital prototype technology. In this process, the use of PDM systems can make the design data of power systems and engines online, and coordinate their design processes to give full play to digital design. The biggest advantage:
1) Collaborative design: Quickly improve the coordination and maturity of the three-dimensional digital model of the power system, improve the efficiency of R&D and design, shorten the development cycle, and make the parallel R&D of multiple models feasible;
2) Unification of product data sources and change management: The design history data and change process can be traced, which is convenient for data version control and technical status management to ensure data security and reliability.
3) Product configuration: Through the definition and derivation of product structure, it can provide a variety of engine and power system configuration schemes for the overall rocket customers to form a series of product packages.
4) Product reuse: Standard parts such as fasteners (such as bolts and nuts) and pipe joints (such as ball heads, nozzles) and borrowed parts overlapped between different models form a "shelf-type" three-dimensional model library to improve The degree of productization improves R&D efficiency and realizes reliability inheritance.
Kyushu Yunjian focuses on the liquid rocket power system products and technology supporting business, and is committed to making this business special and refined. In order to better improve the efficiency of product development, coordination and iteration, and ensure that the quality and technical status of the engines delivered to customers are fully controllable, Kyushu Yunjian has established a PDM system to achieve three-dimensional design collaboration for designers, and products of various sub-systems can be passed Operations such as checkout, modification, and recheck-in can quickly realize the update in the overall product model, make collaboration fast and efficient, and ensure data safety and reliability.
Next year will be a key year for Kyushu Yunjian to achieve mass production and delivery of power products. The technical status management and quality control system of the engine is facing challenges. Kyushu Yunjian PDM system reduces the cumbersome burden of designers on product technical status management. It avoids the hidden danger of uncontrolled technical status, enhances the design force and cohesion of the R&D team, and provides effective guarantee for subsequent parallel R&D, rapid iteration, and high-quality product delivery to customers.
