摘要

摘要: 依据30对混凝土立方块体的单摆和垂直轨道面-面对心碰撞试验结果，利用LS-DYNA有限元程序数值再现试验过程，面-面对心试验数值给予扩展和补充。同时进行了两立方块体面-面非对心、线-面、点-面、线-线及改变块体形状的板板碰撞数值试验。根据物理和数值试验结果，经过回归分析得到描述两混凝土块体间不同碰撞模式下碰撞性能的力学模型。

Abstract: Firstly,the face-to-face central impact experiments with 30 couples of concrete cubic blocks were performed using a pendulum test system and a drop weight test system.Then the experimental processes were recurred by the finite element code LS-DYNA,and the extended and the supplementary numerical tests for face-to-face central impact were carried out respectively.Furthermore,the numerical tests for face-to-face noncentral,line-to-face,point-to-face,line-to-line impacts and the numerical tests that were to study the influence of the shape of concrete blocks were performed.In the end,the models describing the behavior of the different impact modes between concrete blocks were derived from the results of the physical and the numerical tests,by means of the multiple nonlinear regression analysis.
