Abstract
Numerical simulation of dynamic mechanical responses of a rotary centrifuge at different impact velocities and angles is performed. The impact velocities are 25 m/s, 50 m/s and 270 m/s and the impact attitudes are 0° and 45° respectively. Stress fields and failure modes of the guarded body, cavity wall, cover and rotary components are obtained. It indicates that the cavity wall can withstand impact action. The deformation of the cavity wall and cover is elastic when the turntable velocity is lower than 25 m/s. Centrifuge guarded body will be broken when turntable velocity is over 50 m/s. This analysis can guide design and safety assessments of rotary centrifuge.
