Abstract

The invention relates to a computer simulation method for the casting property of a particle-reinforced aluminum matrix composite, which comprises the following steps: acquiring volume fraction or mass fraction of a reinforcement particle of an aluminum matrix composite to be analyzed input into a computer and mass fraction of a matrix composition; calculating and determining physical parameters of a metallic matrix composite by using the data through a performance calculation program of the metallic matrix composite; dividing a space structure grid of a component to be cast, and determining boundary value conditions of the casting process; calculating a flow field, a temperature field and a stress field of the boundary value conditions and cooling parameter added value; analyzing the casting property of the composite according to the calculation result; and if the casting performance is not satisfied, recalculating until a satisfied product is obtained by adjusting the casting process or the addition of the reinforcement particles or adjusting the alloy content in the range of an allowable alloy content. The computer simulation method has the advantages of improving the yield, shortening a new product development cycle, and reducing the cost.
