By using the self-amend Tanner constitutive equation, the response of extrusion pressure to vibrating force field in plastic electromagnetism dynamic extruder was studied.
采用自行修正的Tanner本构方程,对塑料电磁动态塑化挤出机中挤出压力对振动力场的响应进行了研究,建立了振动力场下挤出压力响应的理论模型,分析了振动力场作用下挤出压力降低的原因,并从实验方面进行了验证,结果表明,理论分析的结论是基本合理的。
When thermoplastic material PP was extruded with the periodic mechanical vibration force field,the relational math model between extruding stress and frequency and swing was established.
将正交试验和回归分析法相结合,并利用MATLAB软件中的回归工具箱编程,建立了振动力场作用下热塑性材料PP在塑化挤出时挤出压力与振动强度二因子振幅、频率间关系的数学模型,经理论分析和实验证明,该模型是合理有效的。
