Numerical Simulation on the Casting Process of Gray Iron Brake Pad

Abstract

Based on the analysis of primal process and structure of gray iron brake pad failing early, hydrodynamic software Flow-3D was used to simulate the defect distribution and temperature fields of different improved technology schemes. According to simulation results, the merits and faults of all schemes were investigated and the feasible casting system was determined. The results showed that uniform temperature distribution could be achieved and potential defects mainly distributed in gate riser or nonworking surface when adopting the casting system with single ingate, which gave brake pad better service performance.
