| 摘 要： | 采用Ｌｅｏｎｏｖ本构模型，首次研究了在注射成型中模腔内聚合物熔体的振动剪切流动时所产生的振动剪切应力。结果表明，振动剪切应力的振幅随着聚合物熔体的粘度，振动频率和应变振幅的增加而增加，随着熔体温度的增加而减小。

| Abstract: | Based on Leonov constitutive model,the oscillatory shear stress generated by the oscillatory shear flow of polymer melts in a cavity during injection molding is probed. The results show that amplitude of oscillatory shear stress increases with the melt viscosity, frequency of oscillation and strain amplitude, and decreases with the increase of the melt temperature. |
