[目的]为了考核在接近实战条件下舰载设备的抗冲击能力,[方法]设计并建造大型浮动冲击平台(LFSP),增加冲击载荷的斜挡板结构,在4种具有不同配重、爆源距离及爆源布深的标准考核工况下,对非标试验系统LFSP提供的冲击环境开展仿真和水下爆炸标定试验。针对试验测量信号的低频成分进行分析及处理,并与仿真结果进行相似性分析。[结果]获得了LFSP在标准工况下所能提供的考核能力,证明斜挡板结构的建立满足规范冲击环境的横垂比要求。[结论]所得结果拓宽了后续的LFSP标定试验范围,有利于对更多的舰载设备进行抗冲击性能试验考核。

[Objectives]In order to assess the shock resistance capability of shipboard equipment in close to actual combat conditions,[Methods]the Large-scale Floating Shock Platform(LFSP)is designed and established,with shock load of the oblique baffle structure increased. Under four different standard assessment conditions with different counterweights,explosion source distances and explosion source depths,the simulation and underwater explosion calibration tests are carried out in the shock environment provided by the non-standard test system of LFSP. After the low frequency components of the test measurement signals are analyzed and processed,the similarity of the test results and the simulation results can be analyzed.[Results] The assessment capability of LFSP is obtained under the standard conditions. The establishment of oblique baffle structure is proven to meet the requirements of transverse and vertical impact strength ratio in the normative shock environment.[Conclusions]The results broaden the scope of the subsequent LFSP calibration test,which is conducive to the shock resistance test assessment on more shipborne equipment.
