Robotic Intelligent Assembly Technology and Equipment for Large-scale Aerospace Complex Structures

Prof. Wei Tian

August 7,2021,Yantai

The high-performance requirements of the new generation aerospace vehicles lead to various material systems , larger and complex component structures . The time-consuming process and the unstable machining quality of the traditional manufacturing methodology are unable to meet the quality and accuracy requirements of rapid-changing aerospace products . It is of great urgency to reform the manufacturing concept . Intelligent manufacturing technology based on industrial robots provides a promising solution for the aerospace industry . Accordingly, it is necessary to break through the corresponding core technologies to ensure the high-precision and efficient mass production of the new generation aerospace products .

This talk will discuss the technical requirements and challenges in the field of high-quality , efficient , and precise robotic manufacturing systems for large and complex aerospace components . The corresponding recent achievements of our group will be presented, including error - similarity - based accuracy compensation , multibody transfer matrix dynamics modeling , and machining chatter suppression , multi-source online sensing fusion-based self-adaptation process, and multifunctional end effectors for the robotic manufacturing system . In addition , the task allocation and cooperative control methods of multi-mobile robotic intelligent manufacturing systems will be introduced. Finally, the talk will give a forecast of potential and emerging robotic manufacturing and assembly technologies and portraits for the aerospace industry.
