摘要：
Damage caused by bird impact on a blade in a rotating fan has been idealized as transverse impact of a fluid jet on a semi-infinite, rigid-plastic beam with a centrifugal force acting parallel to the initial axis of the beam. In this preliminary dynamic analysis, the centrifugal force limits travel of the plastic hinges away from the impact point and decreases the deflection of the beam. A kink forms at the impact point; the amplitude of this kink is related to a moment of the impact force and is inversely proportional to the centrifugal force.
