摘要
基于Magma软件,利用DOE田口设计及分析方法分析了某低压铸造汽车用发动机曲轴箱下箱体局部出现的孔隙缺陷及其产生的原因,并对模拟结果进行了优化。结果表明,优化冷却参数及副浇口结构对缺陷的改善显著,改进工艺后缺陷率降低了98%。
Based on the software Magma5.3,low pressure die casting simulations was carried out on the local defects of a lower cylinder blocks.The origination of defects was described and the simulated results were optimized by DOE Taguchi method.The results show that the optimization of cooling parameter and the structure of ingates can improve greatly defects.The defective rate was decreased by 98%.
