冲沙船的位置稳定性及最佳操纵方式

Positional Stability and Optimal Maneuvering of Jet-Sand Ship

冲沙船在水流复杂的航道中冲沙作业时难免受到斜向水流的作用，要保持船舶在既定的航线上作业，要求具有良好的控制位置稳定性．本文应用稳定性理论研究了冲沙船在斜流中工作时的稳定性，并用排序法寻优计算得出最佳的操纵方式．

When a jet-sand ship is at operation,especially in complicated flow,it is hard to avoid the effect of oblique flow. Good positional stability is needed to keep the operation of a ship at a given route. This paper researches the stability of a jet-sand ship working in oblique flow by applying the stability theory, and obtains maneuvering mode by using optimum seeking calculation of the methodical method.
