In this paper base on theories of wave motion and acoustic emission orientation of defects in a plate, scattering of AE wave in a plate with a hole and the problem of wave motion while the plate is operated under impact load are full studied from the angles of theory, experimentation and ansysis beginning from the progation of stress wave in a plate and AE testing. The foundation of the connection with mass of object, velocity and the pressure of the impact point provides the basis and experimental data with wave motion, AE forecast equipment and the evaluation of the fatigue strength.

本文在波动理论和声发射理论的指导下，从撞击荷载作用下的板中应力波传播和声发射检测出发，对板中的缺陷定位、板开孔声发射波散射以及外界物体撞击板时的波动问题进行了较为全面的理论、实验研究和分析研究，建立撞击荷载作用下撞击物质量和速度、撞击点的最大压力的对应关系，为以后的板中波动研究和声发射预警装置提供依据，评价撞击损伤程度提供实验数据。
