摘　　要：用动态光弹性法,对球壳形遮弹板受冲击载荷作用时的应力场进行了实验研究,指出了等厚球壳形遮弹板结构的合理性,同时也分析了反射应力波和应力集中对遮弹板的影响,并据此提出了一些设计原则与改进措施。Stress field of spherical anti-penetration plate acted by impulsive load using dynamic photo elasticity was investigated. The rationality of the plate construction with same thickness was put forward. At the same time the influence of reflex stress wave and stress concentration on anti-penetration plate was analyzed, then some design principles and improvements were proposed.
