塑料挤出机机筒壁厚设计的线性回归模型

摘要

基于力学理论和热平衡原理，建立了塑料挤出机机筒壁厚设计的线性回归模型，并从理论上论证了模型的合理性。利用一些成熟产品的设计给出了模型的解，且据此求得的产品设计参数与经验值高度吻合，明显改进了文献提供的参考值，表明模型在实践中是有效的。%Based on the mechanical theory and the principal of thermal equilibrium , it establishes a mathematical model for the barrel wall thickness design of the plastic extruder , proves the rationality of the model mathemati-cally.According to parameters in the designs of some successful products , it obtains the solution of the mode , the design parameters includes the empirical value .The result improves considerably the reference value provid-ed by the literature. This illustrates the validity of the model in practice .
