阐述了塑料微孔发泡连续挤出成型中的众多技术难点和影响因素。介绍了公理化设计方法的理论基础,用公理化设计的方法对单螺杆连续挤出系统进行了理论上的分析。结果表明:选择合理的设计参数(DP),用正确的顺序就可实现塑料微孔发泡连续挤出系统的功能要求(FR)。运用公理化设计方法可使设计过程层次分明、功能满足设计要求,有助于选用合理的设计方案。 The numerous technical difficulties and influencing factors in continuous extrusion of plastic microporous foams are described. The theoretical basis of axiomatic design method is introduced. The axiom design method is used to analyze the single screw continuous extrusion system. The results show that the functional requirements (FR) of the plastic microporous foam continuous extrusion system can be achieved in the correct order by selecting reasonable design parameters (DP). The use of axiomatic design method can make the design process structured and functional to meet the design requirements, contribute to the selection of a reasonable design.
