Finite Element Analysis of Vibration Fatigue — Finite Element VTOL, eVTOL & UAM

Structural vibration can induce fatigue, durability issues, and undesirable user reactions. Uncontrolled vibrations may impair functionality and pose safety risks.

Vibration-fatigue simulations in the frequency domain predict material life more efficiently than time-domain methods under random loads such as wind and waves.

▶ Simulate shaker tests: random PSD, swept-sine, sine-dwell, sine-on-random
▶ FE models solved for frequency response & modal analyses
▶ Define vibration loads including temperature, static offsets, combined duty cycles
▶ Use fatigue loads for SN and EN lifetime predictions

These FEA-based vibration-fatigue workflows deliver accurate durability forecasts, optimize designs for longevity, and ensure safety under real-world loading conditions.
