A Statistical Approach to Bolted Joint Design
A Two Day Technical Seminar
About the seminar:
This two day seminar was developed to present detailed analysis techniques for engineers with responsibility for design and release of bolted joints. The seminar presents a system analysis approach combining rigorous engineering analysis with statistical techniques to accommodate variation in component geometry, material and process. The analytical process results in statistically quantified joint capacity for multiple failure modes, critical characteristics for the joint, and engineers who understand the system effects for their joints. Techniques presented in this seminar can be used to troubleshoot issues with existing joint designs, as well as assess and optimize upfront design alternatives. The seminar is presented in workshop format, with example problems analyzed during the session. Attendees should bring calculators. Those who prefer to analyze their own joint during the workshop should bring detailed design information (dimensions, tolerances, material properties, surface friction coefficients, torque specifications, load data, etc.,)
Who should attend:
Engineers involved in the design, development or release of components that rely on the performance of quality bolted joints will find this seminar very beneficial. Any technical personnel who want to be able to statistically assess the performance of a bolted joint and optimize their design can benefit as well.
