本文采用自行修正的Tanner本构方程研究了塑料电磁动态塑化挤出机中熔体输送挤出功率对振动力场的响应。建立了振动力场作用下熔体输送挤出功率的理论模型 ,以此为基础模拟塑料电磁动态塑化挤出机的挤出功率 ,并进行了实验研究 ,结果表明理论模拟能够在一定范围内反映实际情况 ,为塑料电磁动态塑化挤出设备的设计和生产应用提供重要的理论指导依据 In this paper, self-correcting Tanner’s constitutive equation was used to study the response of melt delivery extrusion force to vibration force field in plastic electromagnetic dynamic plasticizing extruder. The theoretical model of melt delivery extrusion power under vibration force field was established. Based on this, the extrusion power of plastic dynamic plasticizing extruder was simulated and the experimental study was carried out. The results show that the theoretical simulation can be carried out within a certain range Reflect the actual situation, provide an important theoretical basis for the design and production of plastic electromagnetic dynamic plastic extrusion equipment
