用量纲分析法估算挤压机的生产率和功率

ESTIMATION OF PRODUCTIVITY AND POWER CONSUMPTION FOR EXTRUDER THROUGH DIMENSIONAL ANALYSIS

在塑料、橡胶、食品加工等领域挤压机有着广泛的应用.挤压机的功率和生产率是设计、制造和使用挤压机时需要了解的重要参数之一.然而,传统的计算方法较复杂,本文用相似理论推出了挤压机的生产率和功率的计算公式.简单、实用.

Extruders have come into wide use in plastics、rubber and food processing. The calculation of productivity and power consumption is very important. however,the models now available are all complicated. Based on the similari-ty,this paper presented the π-equation which is relatively brief and practical.
