摘要

摘要: 为了探究大型陆上薄膜罐在飞射物冲击作用下的损伤特征和动力响应特点,根据BS-7777标准设计了两种规格原型保冷模块靶板,并依托大口径冲击加载装置,开展了柔性和刚性弹体撞击靶板试验。研究结果表明:区别于传统Ni9罐,混凝土锥形塞和结痂碎片作用下,保冷结构中的木质胶合板、泡沫板以及波纹板将发生损伤。保冷模块中,胶合板和泡沫板具有较大的吸能能力。钢筋混凝土(RC)结构板未发生贯穿损伤时,冲击能量将主要由RC板、胶合板和泡沫板部分吸收,而薄膜波纹板受影响较小。

Abstract: To explore the damage characteristics and dynamic response features of large thin-film tanks under 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 plywood 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.
