摘　　要：为探明浮力材料配置体积对深海应急救生舱水面耐波性能的影响,运用CFD软件进行浮力材料3种不同配置体积的深海应急救生舱在水面规则波下横摇和垂荡运动的数值模拟,得到横摇和垂荡运动频响曲线,采用统计分析方法,求得3种深海应急救生舱在三级、四级和五级海况下横摇和垂荡运动幅值。分析结果表明,深海应急救生舱浮力材料配置体积对深海应急救生舱水面耐波性能有较大影响,在满足总体要求和上浮过程安全稳定的基础上,浮力材料配置体积越小,深海应急救生舱的水面耐波性能越好。To study the influence of the configuration volume of buoyant material on the seakeeping performance of the deep-sea emergency escape capsule, CFD software was used to simulate numerically the roll and heave motion in regular waves of the deep-sea emergency escape capsule with 3 kinds of buoyant material configuration volume. The frequency response curves of roll and heave motion of three kinds of model were acquired, and the amplitudes of roll and heave motion in the third, fourth and fifth-order sea state were obtained by statistical analysis. The results showed that the configuration volume of buoyant material has great influence on the seakeeping performance of deep-sea emergency escape capsule in waves. On the basis of meeting the general requirements and the safety and stability of floating process, the smaller the volume of buoyant material is, the better the seakeeping performance of the deep-sea emergency escape capsule is.
