Study of Contact Interface Rough Effect on Vibration Stress Wave Propagation

Abstract:

In order to impede stress wave propagation in mechanical boom system, this paper study on contact interface rough effect on stress wave propagation. The model of stress wave propagation was established. On stress wave test platform, it was tested that stress wave through the contact interface roughness between two contact interface. The results show that small surface rough is benefit for stress wave through contact interface; with the surface rough increase, stress wave through contact interface reduce.
