“…It effectively integrates these technologies into an electromechanical integration application system, which combines several hardware and software systems. According to different assembly stages of the aircraft product, aircraft flexible assembly system can also be divided into three stages: component-level flexible assembly, [19][20][21][22][23][24][25][26][27] large component-level flexible assembly, 28,29 and large components alignment and joining.

Aircraft assembly is the most important part of aircraft manufacturing. A large number of assembly fixtures must be used to ensure the assembly accuracy in the aircraft assembly process. Traditional fixed assembly fixture could not satisfy the change of the aircraft types, so the digital flexible assembly fixture was developed and was gradually applied in the aircraft assembly. Digital flexible assembly technology has also become one of the research directions in the field of aircraft manufacturing. The aircraft flexible assembly can be divided into three assembly stages that include component-level flexible assembly, large component-level flexible assembly, and large components alignment and joining. This article introduces the architecture of flexible assembly systems and the principles of three types of flexible assembly fixtures. The key technologies of the digital flexible assembly are also discussed. The digital metrology system provides the basis for the accurate digital flexible assembly. Aircraft flexible assembly systems mainly use laser tracking metrology systems and indoor Global Positioning System metrology systems. With the development of flexible assembly technology, the digital flexible assembly system will be widely used in current aircraft manufacturing.

“…Dassault Aviation Company used Fanuc Robotics S420 in adaptive robot multi-function assembly unit for drilling/riveting of the panel of Rafale and Falcon aircraft (DaCosta, 1996;Jayaweera and Webb, 2007). University of Nottingham applied two opposite robots Comau H4 and Tricept 600 to complete the riveting process of the fuselage panel of CRJ700, which belong to Bombardier Aerospace Corporation (Webb et al, 2003). Li et al (2010) constructed a pneumatic percussive riveting system with a robot and a five-axis bracket.…”

Purpose – The purpose of this paper is to present a dual-robot pneumatic riveting system for fuselage panel assembly, including the system design, dynamic analysis and sensitivity analysis. The dual-robot pneumatic riveting system is designed to improve riveting efficiency and quality, thus finally replace the traditional two-man riveting mode where possible. Design/methodology/approach – The dual-robot pneumatic riveting system has been designed by considering vibration reduction for the tools and isolation for robots. Nonlinear multi-body dynamic model including clearance and collision is established for investigating the dynamic performance and analyzing the systemic sensitivities with respect to the key variations. Semi-implicit Runge–Kuta algorithm is used for solving the dynamic equations and shop experiments are implemented to verify the effectiveness of the numerical simulations. Findings – The simulation results show the tools can be held stably enough for riveting operation and the system sensitivity with respect to robot gesture can achieve the expected level. The experiment validates the proposed system with a good performance, and the riveting quality could adequately meet the requirements. The system is capable of installing an aluminum alloy countersunk 5 mm diameter rivet in 5 s. Practical implications – The dual robot pneumatic riveting system is successfully developed and test. It has been applied in a project of fuselage panel assembly in the aircraft manufacturing industry in China. Originality/value – To replace the traditional manual rivet installation, this paper presents a dual robot pneumatic riveting system and includes both the system design and dynamic analysis.
