Experimental Research on Impact Resistance of Large Thin-Film LNG Storage Tanks
To explore the damage characteristics and dynamic response features of large thin-film tanks un-der projectile impact,this study designed two prototype cryogenic module target plates according to the BS-7777 standard.Leveraging a large-caliber impact loading device,experiments were conducted on the impact of both flexible and rigid projectiles on the target plates.The research results indicated that,unlike Ni9 tanks,the wooden plywood,foam board,and corrugated board in the insulation structure would be damaged under the impact of concrete conical plugs and scab fragments.In the insulation module,the ply-wood and foam board showed a greater energy absorption capacity.When the RC structural plate did not undergo perforating damage,the impact energy would be mainly absorbed by the RC plate,plywood,and foam board,while the thin-film corrugated board was less affected.
