Quick Failure Analysis and Improved Solution of Bolted Joint by Cetim-Cobra

Live Webinar: Wednesday, October 27 | 10:00 - 10:30 AM EDT (16:00 - 16:30 CET)

This webinar features Cobra by Cetim, available through the Altair Partner Alliance.

On a heavy compressor, changing a damaged part is not always possible due to time and cost constraints. When the first threads of a tapped part (M48) have been stripped during a maintenance mistake, a quick repair had to be defined, with minimum part modifications. The new design had to prove equivalent in strength, fatigue, and pressure on sealing rings at service temperature compared to the original design. The robustness of the solution is also analyzed, comparing results for different tolerances. FEM analysis would prove too long. COBRA allowed to design and verify a solution in a very short time, based on a threaded insert and thanks to its fast calculations.

Topics covered include:

  • How to model an assembly with COBRA

  • Analysis of original design

  • Modeling of Threaded insert solution

  • Tightening optimization to reach original design constraints

Who should attend?
Industries where bolted joint is critical and failure needs quick solution without changing parts. i.e. Heavy engine, equipment/machinery construction, lifting, pump, ect.
