Robot Automatic Drilling and Riveting Repair Technology and Equipment for Aviation Delaminated Composite Structure
In the new situation,composites are widely used in the manufacture of high-performance aircraft structures,with the continuous improvement of the service range and service time of China's new generation fighter aircraft,it is increasingly urgent to improve the reliability and service life of the body composite components.With the background of the unique application of automatic drilling and riveting technology in the field of military aviation maintenance,this paper studied the drilling characteristics of the layered damaged component,built and developed the drilling force curve prediction model and the damage interface recognition algorithm,realized the variable parameter drilling of the damaged component,and detailed characterization of the static/dynamic performance of the layered specimen before and after the damage repair.The reinforcement principle and damage repair tolerance of the drilling and riveting repair process are expounded.At the same time,the drilling and riveting process and high-precision robot in-situ drilling and riveting repair equipment for complex layered damage conditions of composite panels are developed,and a complete technical system and intelligent equipment for lamination damage drilling and riveting repair of composite panels are formed.
