METHOD FOR PREDICTING ELASTIC RESPONSIVENESS OF RUBBER PRODUCT, DESIGN METHOD AND ELASTIC RESPONSIVENESS PREDICTION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method for predicting elastic responsiveness of a rubber product by using finite element analysis (FEA), a design method and an elastic responsiveness prediction device.;SOLUTION: In the elastic responsiveness predicting method for predicting elastic responsiveness of a rubber product by using finite element analysis (FEA), the elastic responsiveness of the rubber product is predicted by using a constitutive equation indicating temperature and strain dependency of elastic modulus of a rubber material composing the rubber product, to which an inverse Langevin function g having a statistic bridge point-to-bridge point segment link number n as a variable is applied. As the invert Langevin function, the following mathematical expression 1 is preferred, and as the statistic bridge point-to-bridge point segment rink number, the following mathematical expression 2 is preferred, wherein λ is an elongation ratio or compression ratio, α represents a frequency factor of statistic segment movement, ε represents an activated energy of statistic segment movement, R represents a gas constant, and T represents an absolute temperature.;COPYRIGHT: (C)2008,JPO&INPIT
