HCF and LCF evaluation of Muffler-Turbo Assembly structure

1. FEA Simulation objective:
   HCF and LCF evaluation of Muffler-Turbo Assembly structure and recommend changes for durability where cracks are observed in welds during testing trials.
2. FEA Simulation Methodology:
   Worked on Thermo-mechanical structural analysis of muffler-turbo assembly with transient thermal application on notch changes and transient vibration analysis by applying time-dependent turbo excitation. Our FEA Consultant used Hypermesh for pre-processing and ANSYS solver for simulation of structural integrity. Our FEA Consultant worked using FEMFAT on LCF (Low Cycle Fatigue) with transient thermal simulation with Coffin-Manson evaluation criteria and on HCF (High Cycle Fatigue) with vibration analysis simulation.
3. Outcome and Conclusion
   In LCF, fatigue margins are good and meeting the required criteria. But, Fatigue safety at the toe of the weld is lows with thermal residual stresses in HCF evaluation where cracks are observed. Design iterations are carried out to fix the issue by changing weld locations from the high-temperature zone.

Deflection FEM SImulation analysis of a Model Bridge

1. FEA Simulation Objective:
   The objective of Topology optimization is to get the improvised model for better PI performance.
   In this particular project, the Mission mount’s PI performance has to be improved with the Y – Y-direction unit load condition. Displacement of Y direction is the design constraint bound and Volume fraction/Mass fraction is the design response. Based on the topology design outputs, the Stiffness of the component will be increased by adding mass or ribs/support.
2. FEA Simulation Methodology and Approach:
   Topology Optimization using Optistruct and Sol200 of Nastran
3. Outcome & Conclusion
   we have achieved the PI value target by reducing the Y displacement from 0.028 to 0.014. 50% reduction in Y displacement has been achieved
