摘要
运用3D造型技术设计了一款轻量化高结构强度的枝杈轮辐铝合金轮毂,并对其低压铸造成形过程进行数值仿真,对铝合金轮毂的充型顺序、残余熔体、晶粒尺寸、凝固及卷气等指标或过程进行分析,确定了可实现轻量化枝杈轮辐铝合金轮毂低压铸造成形的工艺条件。根据仿真得到的工艺条件,进行轮毂试验制造,并进行性能测试分析,测试结果表明该轮毂满足车辆使用的性能要求。
3 D modeling technology was used to design a lightweight and high structural strength aluminum alloy wheel hub with branched spoke, and the numerical simulation of its low pressure casting process was carried out. The filling sequence, residual melt, grain size, solidification process and air entrainment of the aluminum alloy wheel hub were analyzed, and the process conditions of low pressure casting of light weight aluminum alloy wheel hub with branched spoke were determined. Based on the simulation process conditions, the wheel hub was manufactured and tested. The testing results show that the wheel hub meets the performance requirements of the vehicle.
