Study on Calculation Method for Hydrostatic Performance of Amphibious Vehicle

The calculation method for hydrostatic buoyant center and float status of amphibious vehicle based on three-dimensional model, mass and center of mass was studied. The condition of hydrostatic equilibrium of amphibious vehicle was introduced. The calculation method of buoyant center using the CATIA program and the computing process of hydrostatic float status were researched. The secondary development for CATIA was processed based on Python. The calculation program for hydrostatic float status of amphibious vehicle was written at last. The accurate and efficient calculation for hydrostatic performance of amphibious vehicle was realized.
