利用浮动冲击平台考核舰用设备抗冲击能力的数值仿真研究

大质量舰用设备一般利用浮动冲击平台进行抗冲击能力评估,但试验过程复杂,费时、费力且花费较多。近些年随着非线性有限元技术的发展,利用有限元法对浮动冲击平台试验仿真考核舰用设备抗冲击性能成为可能。针对浮动冲击平台上舰用设备抗冲击能力进行研究,利用有限元软件ABAQUS进行水下爆炸分析,考虑流固耦合效应,研究浮动冲击平台上的安装设备在不同爆炸距离和不同炸药深度下的冲击响应,为舰用设备特别是大质量设备的抗冲击能力的评估和大型浮动冲击平台的设计提供参考。

Numerical simulation for shock resistivity of shipboard equipment on floating shock platform

Heavyweight must be tested on a floating shock platform(FSP), but the shock test is time-consuming, laborious and spend money. And the finite element modeling and simulation can provide a viable, cost effective alternative to shock tests. The objective of this paper is to examine the response of shipboard equipment in the floating shock platform(FSP) using nonlinear ABAQUS finite element software. These results can provide a reference for the evaluation of shipboard equipment’s shock resistant and the design of the large FSP.
