挤压铸造铝合金转向节开发

Development of Squeeze Casting Aluminium Alloy Automobile Steering Knuckles

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。

cast iron that the knuckles The aluminum alloy automobile steering knuckles was produced by squeezing casting to replace knuckles, which can reduce 56.6% weight by structural optimization design. The results show microstructure and mechanical properties of the squeezing casting aluminum alloy steering exhibit desirable.
