摘　　要：利用弹性理论和近似方法分析了四边简支弹性薄板在爆炸荷载作用下的动态响应历程.根据薄板运动微分方程和爆炸荷载的特点,从理论上求解了薄板运动各力学参量.结合量纲分析理论,对30种不同的工况进行了计算,最后建立了较合理的工程计算模型.模型拟合结果与理论计算结果吻合,可作为工程计算的参考.With elastic theory and approximate calculation, the dynamic response of elastic thin plates with four edges simply supported under blast loading is analyzed. All mechanical quantities are solved based on differential equations of thin plates and characteristic of blast loading by theory. With dimensional analysis, 30 cases have been calculated, and a reasonable model for engineering calculations built up.
