摘要：

In order to study the influences of tendon prestressing force on the protective performance, the fine FE models of Ling-ao prestressed containment and the A320 large commercial aircraft were established, respectively. The impact process was simulated by using the commercial FE software LS-DYNA, and the aircraft velocity was set 215 m/s impacting on the weakest position of nuclear containment. The results show that the impact force-time history curves are similar to those presented by other related literatures. With the increase of prestressing force, the containment damage becomes slighter and the maximum impact displacement decreases to a stable value. Besides, a formula of maximum impact displacement with different prestressing forces is fitted. © 2016, Editorial Department of Transaction of Beijing Institute of Technology. All right reserved.
