Glass viscoelastic mechanical parameter derivation method based on creep flexibility main curve

The invention discloses a glass viscoelastic mechanical parameter derivation method based on a creep flexibility main curve, which comprises the following steps: firstly, carrying out compression creep test on a cylindrical glass sample at a plurality of temperatures above a glass transition point temperature to obtain creep flexibility curves at the plurality of temperatures; then, a creep flexibility curve at the multiple temperatures between the appropriate starting time and the appropriate ending time is intercepted; then selecting the lowest temperature from the plurality of temperatures as a reference temperature, keeping the creep flexibility curve at the reference temperature immovable, and translating the creep flexibility curves at other temperatures rightwards so as to construct a creep flexibility main curve function; and finally, converting the creep flexibility main curve function into a time domain shear relaxation modulus, and calculating empirical parameters in the simple thermal rheological
