Customer Challenge
We needed to validate the strength of a UAT ceiling using simulation and analysis to ensure it has the correct design to integrate safely with the rest of the vehicle.
Scope
- To carry out a sophisticated software-driven FEA to check the design.
- To perform FEA for proof loads, service loads and bolt calculations. Evaluate the results and preparation of reports
Solution
- Input study of ceilings
- Preparation of FE model for the design using Hypermesh preprocessing software
- Check the modal analysis, our model being that the first frequency had to measure greater than 20 Hz
- Run the analysis for the identified combination of load cases, then evaluate the results for stresses and displacements
- Perform the bolt calculations and carry out the preparation of analysis and calculation reports
Features
- The result of the analysis was the first frequency was above 20Hz
- The stresses were within the allowable limit for parent, weld and bolted regions
Benefits
- Assurance – no changes in the design as the first frequency in modal analysis and the stresses are within the allowable limit for parent, weld and bolted regions.
