Course Overview
Design & Analysis of Bolted Joints Training Course – Hands-on
In Design & Analysis of Bolted Joints Training helps everyone involved in developing hardware for space missions (or any other purpose, for that matter) 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. The objectives of this course are to:
Build an understanding of how bolted joints behave and how they fail
Impart effective processes, methods, and standards for design and analysis, drawing on a mix of theory, empirical data, and practical experience
Share guidelines, rules of thumb, and valuable references
Help you understand NASA-STD-5020
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 course includes many examples and class problems. Participants should bring calculators.
Design & Analysis of Bolted Joints Training Course – Customize it
- We can adapt this training course to your group’s background and work requirements at little to no added cost.
- If you are familiar with some aspects of this training course, we can omit or shorten their discussion.
- We can adjust the emphasis placed on the various topics or build the training around the mix of technologies of interest to you (including technologies other than those included in this outline).
- If your background is nontechnical, we can exclude the more technical topics, include the topics that may be of special interest to you (e.g., as a manager or policy-maker), and present the training course in manner understandable to lay audiences.
