摘要
Abstract
The dynamic response of a ship scaled model subjected to underwater explosion is studied using numerical simulation and realistic explosion tests. Based on the characteristic parameters of longitudinal strength and local plastic distortion, the grade evaluation of anti-deflection capability of the model is conducted. The results show that the acceleration response and damage grade increase with the shock factors, and the local response is related to the vibration mode. When the damage grade based on the local plastic distortion reaches the highest value, the damage grade based on longitudinal strength is not necessarily the highest. The result is of significance for evaluation of ship shock tests.关键词
