摘要
针对汽车凸轮轴承盖一体化压铸成型气孔率要求低的问题,运用PQ2图优化凸轮轴承盖压铸模设计,采用MAGMA软件进行有限元模型的建立及模拟分析,预测铸件成型气孔率,并通过正交试验、遗传算法进行凸轮轴承盖一体化压铸成型工艺优化。通过确定最优成型工艺参数组合,再进行成型模拟分析和生产验证,对生产的汽车凸轮轴承盖进行X射线探伤检测。结果表明,通过PQ2图优化模具设计及正交试验,遗传算法优化压铸成型工艺参数,有效控制汽车凸轮轴承盖压铸成型气孔率,提升了铸件品质,缩短了铸件开发及生产周期。
In response to the high porosity requirements for the integrated die-casting of automotive cam bearing cap,the PQ2 diagram was used to optimize the design of the die-casting die for the cam bearing cap,and the MAGMA software was adopted to establish the finite element model and conduct simulation analysis to predict the porosity of the casting,and the integrated die-casting process of the cam bearing cap was optimized through orthogonal tests and genetic algorithms.By determining the optimal combination of forming process parameters,followed by forming simulation analysis and production verification,X-ray flaw detection was conducted on the produced automotive cam bearing caps.The results showed that through the optimization of die design by PQ2 diagram and orthogonal tests and the optimization of die-casting process parameters by genetic algorithm,the die-casting porosity of cam bearing cap was effectively controlled,the quality of castings was improved,and the development and production cycle of castings was shortened.
