高速破片撞击充液容器时容器壁面的损伤
|
摘要
为研究高速破片(钨球)撞击充液容器(贯穿前后壁面)时容器壁面的毁伤情况,利用ANSYS/LSDYNA对该过程进行了数值模拟,分析了破片撞击动能对充液容器前后壁面毁伤程度的影响,并进行实验验证。结果表明:高速破片撞击充液容器形成的液压水锤对充液容器前后壁面的破坏程度可分为3个等级,即前后壁面均未出现裂纹、前壁面没有出现裂纹后壁面出现裂纹和前后壁面均出现裂纹且后壁面呈花瓣式开裂;破片撞击充液容器过程中,前后壁面的最大变形量和前后壁面的裂纹总数随破片撞击动能的增加而增大。
We analyzed the influence of the impact energy on the damage degree of the front and rear walls and verified it by experiments.The results show that the hydrodynamic ram formed by a highspeed fragment impacting the liquid-filled vessel affects the vessel's front and rear walls and that the degree of the damage can be divided into three levels:the cracks are not observed on the front and rear walls;cracks are observed on the rear wall surface but on the front wall surface;cracks are observe on both front and rear walls and the rear wall is petal-type cracked.The maximum deformation of the front and rear walls and the total number of cracks in the front and rear walls increase with the increase of the impact energy of the fragments during the fragment impact process of the liquid-filled vessel.
