000003777 520__ $$2eng$$aThe paper deals with 3D numerical model of an ellipsoidal particle collision with rough bed. The stochastic method of the contact point is based on the concept of contact zone. The translational and rotational particle motions are taken into account. The two – parameters (restitution and friction coefficients) system of the impulse equations are used. The dependences of values of the particle translational and angular velocities immediately after the collision on the values immediately before the collision are obtained for two collision patterns: impact with slip and impact without slip. The model can be used, particularly, as the part of the ellipsoidal particle saltation in channel with rough bed.
