In order to obtain the molten metal flow pattern during vibration casting and to optimize vibration parameters

dynamic mesh and two-phase flow model were coupled to simulate flow field in vibration cavity

and orthogonal design was conducted to optimize the vibration parameters.The results show that the vibration can improve obviously the flow conditions of liquid metal in cavity

and reduce the filling time and the wall shearing stress.The optimization parameters were presented as follows:vibration frequency of 30Hz

amplitude of 0.3mm and the vibration direction of 45°to the horizontal direction.The practical experiment verifies that the optimized parameters are helpful to obtain the better filling effects.
