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。
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 dynamic response equations of cable-segments.The cable dynamic force with significant wave height 5 meters ＆ excessive period 4 second at the ship-end is simulated.The result has an important meaning in avoiding resonance of systems and extending the cable life.
