A mathematical 3D model is presented, fully describing the impulse compaction process of moulding sands. The model is based on the models of the impulse head dynamics as well as of the deformation and compaction processes of moulding sand. The deformation and compaction processes were modelled on the grounds of the viscoelastic rheological model of moulding sand. It was found that knowing the and coefficients characterising viscous and elastic properties of moulding sand makes the necessary and sufficient condition for simulation testing of the developed model. The coefficients can be determined by ultrasonic testing of moulding sand. The simulation and experimental research of the impulse compaction process proved that the developed model describes the impulse compaction process very well.
