Abstract:
A simulation method for estimating performance of a product made of a viscoelastic material, comprising the steps of:measuring at a moment a value of a strain, a strain speed, and a stress generated in said viscoelastic material in a measuring condition equivalent to a state in which said product is actually used; deriving time history data of a viscosity resistance of said viscoelastic material from time history data of said strain, said strain speed, and said stress and a viscoelastic model set in consideration of a viscosity of said viscoelastic material; setting said product made of said viscoelastic material as a product model of which performance is analyzed and inputting a relationship among said strain, said strain speed, and said viscosity resistance to said product model; and simulating in consideration of a phenomenon that said viscosity resistance changes depending on a variation of said strain and said strain speed, whereby the performance of said viscoelastic model made of said viscoelastic material is estimated.
