为探讨动态成型工艺参数对聚合物动态加工功耗的影响规律,文中采用熔体输运模型研究自行研制的同轴圆筒动态流变装置电机功耗对振动力场的响应,建立了振动力场下电机动态输出功率与稳态输出功率差的理论模型.对同轴圆筒动态流变装置电机功耗进行了测量,并与理论计算功耗进行比较,发现理论模型能较好地预测电机功耗随振动参数的变化,实验数据和理论模型均表明动态加工电机功耗随振动频率和振幅的增大而减小.文中还通过实际加工中脉动注塑机能耗随振动频率和振幅的变化证实了理论模型的可行性.

In order to explore the influence law of dynamic processing parameters of polymers on the power consumption, the response of electromotor power consumption of a self-designed coaxial-barrel dynamic rheometer (CBDR) to the vibration force field was analyzed based on the melt conveying model, and a theoretical model describing the power difference between the dynamic output and the steady output was established. Then, the electromotor power consumption of the CBDR was measured and was compared with the theoretical one. It is found that the proposed theoretical model is effective in predicting the change of practical electromotor power consumption with vibration parameters. The experimental and theoretical results indicate that the power consumption decreases with the increase in vibration frequency and amplitude. Moreover, the feasibility of the proposed model is verified by the actual change of energy consumption of vibration injection machine.
