Aircraft lug joint is the key part of load transfer. In order to improve the safety of lug joint, on the premise of meeting the design requirements of static strength and fatigue, the composite connection lug structure design technology of different metal materials is proposed in this paper. Firstly, the damage safety design and life reliability analysis of the lug structure are studied theoretically. Secondly, based on the concept of damage safety design and the design principle of deformation coordination, the design method of composite connection lug with deformation coordination is proposed, and the thickness ratio of single ear is 0.8:1:0.8. Finally, the reliability of the composite lug is analyzed. The results show that the structural design scheme of aluminum-titanium composite ear piece can meet the requirements of static strength and damage tolerance, and compared with the conventional ear structure, the failure probability of structure mission life is greatly reduced when the weight of the composite connection lug is only increased by 4.9%. The proposed method can effectively guide the structural design of composite ear piece.

Numerical control (NC, for short) forming machine is kind of digital forming equipment, which is based on the development of manufacturing technology without pattern, and can get mold by processing module directly, and its mechanical structure is mainly composed of the main structure, moving system, tool system and other components. The main structure is not only the foundation and framework of the entire machine, but also the most important component bearing pressure. The moving system is the most critical part of forming machine to achieve its fundamental function. Therefore, the design and development of the main structure and moving system have directly impact on the performance and service life of the forming machine, which is an important factor to reflect the level of the overall design. In this paper, structural static analysis of the main structure and moving system was made through finite element numerical simulation, the more reasonable scheme was optimized, by which the safety and reliability of forming machine was ensured. The research results can provide the necessary technical support for the structural design of NC forming machine.

Abstract FROSTLINE is a fine-grain, columbium-treated carbon steel designed to be an economical solution to structural design requirements at cold temperatures. Available in plate thicknesses up to 6 inches, it offers high levels of toughness at temperatures to 80 F and higher strength levels than conventional carbon steels. Frostline also offers excellent welding characteristics, because of its low carbon equivalent. This datasheet provides information on composition, physical properties, elasticity, and tensile properties as well as fracture toughness. It also includes information on forming, heat treating, and machining. Filing Code: CS-67. Producer or source: Lukens Steel Company.
