摘  要:
According to the analysis of field tests of several typical working conditions, the vibration response of a tractor cab was described as a narrow band vibration. In order to simulate it, this paper explained the equivalence of a narrow band vibration and a sinusoidal vibration and established a strengthened test spectrum which was compiled from single working condition spectrums. Instead of a test of narrow band vibration, a test of sinusoidal vibration was applied to the tractor cab. It made the fatigue life test method of a tractor cab simplified. The result of test was expected.
