COURSE OVERVIEW
Design and Analysis of Bolted Joints Training help everyone involved in developing hardware for space missions (or any other purpose, for that matter) that has been affected by problems with mechanical joints. Common problems include structural failure, fatigue, unwanted and unpredicted loss of stiffness, joint slipping or loss of alignment, fastener loosening, material mismatch, incompatibility with the space environment, mis-drilled holes, time-consuming and costly assembly, and inability to disassemble when needed.
Includes a close look at NASA-STD-5020, Requirements for Threaded Fastening Systems in Spaceflight Hardware, which was approved in March 2012 for use throughout NASA. Also, the Design and Analysis of Bolted Joints Training course includes many examples and class problems. Participants should bring calculators.
