VISCOELASTIC RESPONSE PERFORMANCE PREDICTION METHOD, RUBBER PRODUCT DESIGN METHOD, AND VISCOELASTIC RESPONSE PERFORMANCE PREDICTION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method of predicting viscoelastic response performance of a rubber product using a finite element analysis (FEA), a design method and a viscoelastic response performance prediction device. SOLUTION: This viscoelastic response performance prediction method for predicting the viscoelastic response performance of the rubber product using the finite element analysis is characterized by predicting the viscoelastic response performance of the rubber product using a constitutive equation expressing distortion dependency of viscoelastic characteristics of the rubber product using a parameter representing temperature dependency. Mathematical expressions 20, 21 are preferable as the constitutive equation expressing the distortion dependency of the viscoelastic characteristics, and a mathematical expression 33 is preferable as the parameter representing temperature dependency.
