摘要 该文采用动态仿真工具SIMULINK ,以描述高聚物蠕变现象的四元件模型为基础 ,成功模拟了高聚物在交变力场作用下的滞后现象。研究结果表明 ,只要对四元件模型稍作修正 ,即可用来描述高聚物的滞后现象和力学损耗 ,从而使之不但适用于描述高聚物的静态力学松弛 。 ThehysteresiseffectofpolymerwassimulatedoneffectofalternatestressbyMatlab/Simulink ,adynamicemulationtool,onthe baseoffour-componentmodel,whichwasusedforthecreepofpolymer.Itwasfoundthatthefour-componentmodelcanbeusedtode scribethehysteresiseffectandthemechanicallossofpolymeronlyifthemodelwasmodifiedalittle.Asaresult,themodelwasavailableto boththestaticandthedynamicmechanicalrelaxationofpolymer.
