【摘要】 动光弹与爆破加载的同步问题对保证实验成功十分重要。本文对利用沙汀相机和动态激光照相机进行爆破模型实验的同步方式差异进行了分析,指出了各自不同的特点和实施同步的关键点。利用激光光测系统同时获得无限平面集中爆破载荷等差条纹图和等和条纹图,用两种不同的解法进行了动应力场定量求解,对两种解的结果差别进行了研究,分析了各自的适用范围。更多还原

【Abstract】 The synchronism of dynamic photo-elasticity with blasting load is important to the success of experiment research. In this paper the difference of the method of synchronism in blasting model test using Schardin camera and laser photography system was analyzed.The article described the features of these methods and the key points for the synchronization.The isochromatic and isopachic fringe patterns in infinite plane concentrating explosion load were simultaneously obtained by laser photography system. The dynamic stress field was evaluated with two different methods by study the difference of the evaluating results and the conditions applied.更多还原
