Mechanika ltd successfully executed a complete analysis of a buffer air valve used on a range of small business jets. The analysis carried out utilised hand calculations plus FEA and included:
- Pressure loading
- Shock loading
- Thermal stress and transient analysis
- Manoeuvre loading
- Harmonic response on engine
- Fault loads
- High cycle fatigue
- Low cycle fatigue
- Damage tolerance
The harmonic response analysis returned resonant frequencies that coincided with shaker test results to within 5% for the most damaging mode.
