Accelerated Fatigue Bench Test of Driving Axle Housing Based on FEA

By conducting static strength analysis, fatigue life prediction, strain history acquisition and time correlated damage analysis under the FE simulation circumstance, the deducted load spectrum for accelerated fatigue bench test of a special construction vehicle driving axle housing was acquired. The result of bench test shows that the deducted load spectrum can significantly reduce the test period when accurately preserve damage that the part suffering.
