摘　　要：对于新研舰载设备,各国海军均要求其抗冲击性能满足考核标准才可装舰使用。为了进行对潜艇内大型设备在接近实战条件下的考核试验,设计并建造了模拟潜艇的试验舱段平台。在不同爆源距离的标准考核工况下,数值模拟了试验舱段的水下爆炸试验,对试验舱段提供的冲击环境进行预报,并根据数值模拟结果及相关理论计算拟定试验工况后,完成了3次水下爆炸试验。通过对实测冲击谱的圆整及插值拟合分析得出,试验舱段的建立满足大型设备冲击环境指标的横垂比要求,为进一步考核潜艇内大型设备抗冲击性能提供了必要的环境。For the newly developed shipborne equipment, navies of all countries require their impact resistance to meet the assessment criteria before they can be installed on ships. In order to conduct impact examination tests of a submarine’s large equipment under the condition near actual combat, the platform to simulate a submarine’s test section was designed and manufactured. Under standard examination conditions with different distances from the blast source, underwater explosion tests of the test section were numerically simulated to predict shock environment provided by the test section. According to numerical simulation results and relevant theoretical calculations, test conditions were drawn up and three underwater explosion tests were completed. The actually measured impact spectra were analyzed through rounding and interpolation fitting. It was shown that the establishment of the test section meets the requirement for the ratio of transverse to vertical of the large equipment shock environment index;the study results provide a necessary environment for further examining submarine large equipment’s impact resistance.
