水下爆炸作用下中型浮动冲击平台毁伤特性研究
|
摘要
以标准中型浮动冲击平台为目标,采用数值仿真以及理论分析的方法对其在水下爆炸作用下的毁伤情况进行研究。首先对仿真方法的正确性进行验证,其次结合平台工作情况选择合适的工况及测点进行仿真计算,给出毁伤及冲击环境的仿真计算结果,总结不同冲击因子对平台冲击环境的影响规律;然后采用理论方法对目标毁伤情况进行计算,参照BV043/85标准对平台冲击环境进行预报,并与仿真计算结果进行比对分析。结果表明,仿真方法与理论分析方法所得到的水下爆炸作用下所得毁伤情况比较吻合,在此基础上结合标准规范给出平台承载重量的范围。
This paper studies on damage effect of Intermediate Floating Shock Platform by theoretical analysis and numericsimulation. Firstly the correctness of the simulation method is voritied. Then the shock environment characteristics of IFSP arecalculated by the standard working condition and measuring point,and the change rule of environment characteristics of IFSP issummarized on different shock factor. Damage effect of target is calculated by theoretical method. Environment characteristics ofIFSP is predicted,and compared with simulation calculation effect. The results show that the effect of theoretical analysis andsimulation calculation are consistent. Based on the conclusion the platform bearing weight range is given combining on the standardsand guidelines.
