"This is the forum where the aerospace community gathers to present and discuss current and future challenges, opportunities and requirements of next-generation aircraft, product and systems. Focusing on fasteners, tooling, automation, materials, structures and manufacturing, the technical program will provide aircraft technology and application essential to aerospace professionals"--SAE Web site.
Today, virtually every Aerospace manufacturer is using some type of automated fastening machinery. The seventeenth annual Aerospace Automated Fastening Conference and Exposition (Aerofast '99) focused on the advancement of Automated Fastening in the Aerospace Industry. Technical presentations on these areas: -- Improvements in Existing Processes Using Automated Fastening -- Assembly Technologies & Manufacturing Processes -- Quality Advancements -- Advancements in Automated Fastening
"Temporary fasteners are required in aircraft assembly, especially in the assembly of wings, fuselage, and aircraft skin's substructure prior to drilling holes for permanent fasteners by automated drilling machines. The objective was to develop a temporary fastener that can be installed, clamped, loosened, and removed from one side with a short head length. Published papers, web pages and patents relating to temporary fasteners were reviewed. Then by considering the ability to meet the operation requirements and concerns, a temporary fastener was designed with the following advantages: · a simple structure that can be easily fabricated · a short head length to save assembly time and reduce the risk of collision between the drilling machine and the head of temporary fastener · an inner thread driver to provide a high clamping load · capable of single-sided one-man operation. The designed fastener was fabricated using VascoMax C300 material. Finite element analysis (FEA) was employed to simulate the working process of the fastener with different design parameters. Deformed shapes of the temporary fastener flexible fingers after heat treatment were simulated, and the simulation results were validated with physical prototypes using a reverse engineering approach. The design parameters of both the flexible fingers and the spring were analyzed, and the analytical data was validated with experimental data measured by strain gages. During the fastener working process, a load cell and a torque sensor were employed to measure clamping force and tightening torque, respectively. The measured results agree well with FEA predictions."--Abstract, page iii.
