摘要：

Pseudo-cylinder parameterization was discussed and included in the 3D model (IMPACT35) to predict the translation and orientation of falling mine with near cylindrical shape through air, water, and sediment. The drag and lift forces and torques can be easily calculated using the existing formulas to calculate the drag and lift coefficients, after the pseudocylinder parametrization. A model-data comparison showed that IMPACT35 improved the prediction capability drastically versus the 2D model (IMPACT28) with an order of error reduction in the mine burial depth. It was concluded that pseudocylinder parametrization is valid only for near-cylinder mines.
