Abstract
Flexible Segment Model (FSM) based optimization method is proposed as a robust dynamics calculation method for underwater Moving Slender Bodies (MSBs). In the method, the underwater MSB is divided into a series of flexible segments, their deformations are analyzed individually, and the dynamics calculation is accomplished by the optimization of a mechanical equilibrium function in a simple form. Because the whole deformation of a MSB is decomposed into small 'curve' deformations of all segments, the dynamics calculation needs a relatively small number of segments for accuracy. The comparison with experimental results shows that the numerical results by FSM based optimization method have good accuracy. Moreover, the tests of sensitivity and error tolerance show the numerical calculation by FSM based optimization method has high stability.
