The embodiment of the invention discloses a viscoelastic material parameter determination method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring creep test data of a to-be-measured viscoelastic material; according to the creep test data, calculating the creep compliance and Poisson's ratio of the to-be-measured viscous-elastic material through a generalized Kelvin model; determining an elastic matrix based on the creep compliance and the Poisson's ratio, and calculating initial data according to the elastic matrix; calculating first creep strain data of a first time period based on the initial data, and calculating first displacement data of the first time period according to the first creep strain data; and determining first stress data according to the first displacement data, and determining second displacement data and second stress data of the to-be-measured viscoelastic material in a second time period in the preset condition based on the first
