Abstract:In order to solve the problems of low efficiency, poor precision, and intensive labor in the assembly process of commercial turbofan engines with large bypass ratio, the assembly of the low-pressure turbine of commercial turbofan engine was analyzed, and an intelligent assembly system suitable for this component was established by combining intelligent assembly technology. The system adopts various information-based intelligent assembly technologies, and combines a variety of sensors and detection methods to build a low- pressure turbine finished product assembly platform, and most of the assembly processes can be highly automated. The assembly platform was tested and verified by simulated parts of the commercial turbofan engine. The results show that, compared with manual assembly, the assembly efficiency of the low-pressure turbine intelligent assembly platform is more than doubled, the production efficiency is increased by 20.19%, in which the assembly time is shortened by 62.5%, the manual operations are greatly reduced, the operating cost is reduced by 23.52% on average, and the energy utilization rate is increased by 4%. The intelligent assembly technology of low-pressure turbines is feasible.
