Application of bifurcation analysis to the stability control of underwater high-speed vehicles;

Modeling and stability control of underwater high-speed vehicle

For accurate analysis of the motion of underwater high-speed vehicle at a high speed, using the MATLAB, a modularization simulation model of underwater high-speed vehicle was implemented and simulated.

Computation of eigenvalues of acoustic-structural coupled vibration for underwater structures;

Using three-axis accelerometer ADXL330,a single monolithic IC,based on micro electromechanical systems(MEMS),an accelerator transducer for underwater structure was designed and applied to a vibration measurement system of long pipeline gates.

The numerical calculation of underwater structure s acoustic radiated field has been carried out with the FEM and I-FEM.

The paper briefly introduced the development and state of the art of high performance marine vehicles around the world, analyzed the performance and future development trend of various types of the analyzed future high speed shipping market in China, and proposed relevant countermeasures to be adopted to develop high performance marine vehicles for Chinese shipbuilding industries.
