摘要

采用铝合金挤压铸造间接挤压工艺代替球铁生产转向节

结合结构优化设计

使转向节质量降低了56.6%

轻量化效果显著。开发过程采用模拟计算与实际试验相结合的方法

得到的铸件组织和力学性能优良

且静力破坏试验、耐久试验指标均满足使用要求。

Abstract

The aluminum alloy automobile steering knuckles was produced by squeezing casting to replace cast iron knuckles

which can reduce 56.6% weight by structural optimization design.The results show that the microstructure and mechanical properties of the squeezing casting aluminum alloy steering knuckles exhibit desirable.
