摘　　要：为了从理论上分析和验证振动力场引入到注塑成型过程中对注塑成型过程能量消耗的影响,在传统三大方程的基础上借助M axwell和改进的Tanner本构方程对注塑机成型过程中的能量消耗进行了理论推导。在此基础上通过实验验证了该数学模型的正确性和可靠性。结果表明:计算结果与实验结果能够很好地吻合,振动强度越大,吻合程度越高。随着振动强度的增加,注塑成型过程中的能量消耗迅速下降。Energy consumption expression of polymer balance equations, Maxwell and modified Tanner constitutive during injection process was developed based on conventional equations to explore analysis the energy consumption of polymer injection process. Validity and reliability of the mathematical model were verified too. The result showed that results obtained from experiment accorded well with calculated ones. With the increase of the vibration intensity the deviation was narrow, and the energy consumption decreased sharply
