Abstract：Steel steering knuckle casting is a key component in the steering system of wheeled vehicles. After machining, no defects are allowed in the axial part. According to the original casting process, casting defects such as sand inclusions were found to exist in the large arc part with a thermal center of the product. To solve this problem, optimization of the casting process design is conducted using casting CAE simulation technology to realize the visual analysis of the simulation results. Actual manufacturing shows that the optimized process significantly reduces casting defects and continuously improves the product quality qualification rate.
