Abstract

Fatigue rupture happened to the horn bracket system during the vibration physical test.Mode,dynamic stress and vibration acceleration calculations were performed after analyzing the test result.Boundary conditions.damp parameter and the method of fatigue analysis brought by resonance were confirmed.Then improved structure scheme was given out,and the new structure passed the vibration physical test.The result shows when FEA and physical test combined,vibration fatigue performance of parts can be forecasted.
