摘要
合理的压射工艺对于提高压铸生产效率和降低压铸件缺陷意义重大。本文针对压铸过程中的压射工艺参数的选择提出了基于灰色关联和D-S证据理论相融合的决策方法,摆脱了以往依托专家经验的试错法,使得压射工艺参数的选择更具有科学性。实验证明本文提出的方法在满足准确性的同时具有高效性。
Reasonable injection process is of great significance to improve the production efficiency and reduce the defects of die casting.In this paper,a decision method based on grey correlation and D-S evidence theory is proposed for selecting injection parameters in die casting.which is more scientific than the trial-and-error method relying on expert experience in the past.The experimental results show that the present method is not only accurate but also efficient.
