摘要: 目前国内缺少对 GJB 1060.1—1991 中规定的冲击设计载荷与 GJB 150.18—1986 中规定的试验工况所对
应的试验载荷的相关性研究,利用建立的中量级冲击试验多自由度质量刚度阻尼动力学模型,针对船体安装单自由度
刚性设备(设备本身假设为刚体),开展 GJB 150.18—1986 中规定工况下的冲击试验载荷计算,拟合得到冲击试验谱
速度的计算公式,发现 GJB 150.18—1986 规定的标准工况下冲击试验谱速度在 1.75~2.40 m/s 之间。与 GJB 1060.1—
1991 中规定的 DDAM(dynamic design analysis method)方法计算得到的冲击设计谱速度进行对比,分析设备安装频率、
设备质量、摆锤高度等对试验载荷与设计载荷相关性的影响。结果表明,整体上冲击设计载荷大于冲击试验载荷,但
在槽钢跨距较大(大于 90 cm)的特定工况,可能出现冲击试验载荷更大,并给出了冲击设计谱速度与冲击试验谱速度

Abstract: At present, there is a lack of research on the correlation between the shock design load specified in GJB 1060.1—
1991 and the shock test load corresponding to the test conditions specified in GJB 150.18—1986 in China. Without a clear
understanding of the severities of shock design loads and shock test loads, it is impossible to accurately guide the anti-shock
design for the evaluation and testing of ship equipment. Taking the medium-weight shock test specified in GJB 150.18—1986
standard as a case, a multi-degree-of-freedom mass stiffness damping dynamic model is established. Considering the single-
degree-of-freedom rigid installation equipment installed on the hull (the equipment itself is assumed to be rigid), the shock test
load calculation under the standard conditions can be carried out. It can be found that there are upper and lower limits for the
shock spectrum velocity of the test load anvil where the lower limit is about 1.75 m/s and the upper limit is about 2.40 m/s. A
calculation formula of the shock test spectrum velocity is fitted. Based on the DDAM (dynamic design analysis method)
method and the shock design spectrum value specified in GJB 1060.1—1991, the shock design spectrum velocity calculated is
compared with the shock test load, and the influences of equipment installation frequency, equipment mass and pendulum
