针对舰船设备在水下爆炸冲击下的安全性问题，通过1∶3缩比模型数值模拟，探究实际加工和安装等偏差对设备基础冲击响应的影响规律。建立实尺度与缩比模型，分析质心偏移、隔振器数量、刚度及阻尼变化对缩比模型基础垂向加速度、速度、位移的影响。研究表明设备质心偏移、隔振器数量及刚度变化（±20%）对基础加速度峰值影响小于5%，速度与位移的影响可忽略；隔振器阻尼变化（±20%）导致加速度峰值差异达11%，需重点关注。研究结果阐明了舰船设备缩比模型简化规律，为舰船缩比模型设计及抗冲击性能评估提供借鉴作用。
To address the safety of shipboard equipment under underwater explosion shocks, this study investigates the impact of actual manufacturing deviations on the shock response of equipment foundations through numerical simulations of a 1∶3 scaled model. Full-scale and scaled models were established to analyze the effects of centroid offset, variations in the number of vibration isolators, and changes in isolator stiffness (±20%) and damping (±20%) on vertical acceleration, velocity, and displacement. The results indicate that centroid offset, variations in the number of isolators, and stiffness changes (±20%) have a limited influence on the peak acceleration (≤5%), with negligible effects on velocity and displacement. However, damping variations (±20%) significantly alter the peak acceleration (up to 11% difference), necessitating strict control in design. These findings clarify the simplification rules for scaled models of shipboard equipment and provide critical insights for the design and anti-shock performance evaluation of scaled models.
