Abstract:
Taking the steady motion status as a starting point, according to the modeling of actual state of theoretical analysis, a predigested model of supercavity vehicle was established, and relationship expressions of these angles were obtained when the movement of supercavity vehicle was stable. A theoretical analysis on the stability of underwater high-speed movement in the movement simulation program was conducted and the simulation results were given. Then the force status of the supercavity vehicle was elicited from the results. The finite element analysis was carried out based on the stability at all angles obtained from simulation results. Taking a pilot model as example, the Monte Carlo method was adopting to analyze the reliability with the given state of force and displacement. The result indicates that this method is feasible.
Key words:  supercavity vehicle  stabilization analysis  structure reliability analysis  finite element  Monte Carlo method
