| 摘 要： | 分析了与船舶相连的水下垂直吊放系统动态响应,对三维缆索分段动态响应方程采用了凝集参数法和平均切向量技术,在5 m有义波高和4 s超越周期下模拟了吊索的动态张力.结果对避免系统谐振,延长缆索寿命都有重要意义.

| Abstract: | Dynamic response of underwater vertically suspend systems connected to the surface ship is discussed. The lumped mass model is applied and an averaged tangential vector technique is included in three-dimensional dy-namic response equations of cable-segments. The cable dynamic force with significant wave height 5 meters & exces-sive period 4 second at the ship-end is simulated. The result has an important meaning in avoiding resonance of sys-tems and extending the cable life. |
