Equivalent treatment method and system for glue injection flow channel during filling analysis of metal rubber composite product and medium

The invention discloses an equivalent treatment method and system for a glue injection flow channel during filling analysis of a metal rubber composite product and a medium. The method comprises the following steps: modifying a three-dimensional solid assembly model of a metal rubber composite product mold containing a rubber injection runner sprue; converting the circular pouring gate into a rectangular pouring gate according to an equal-area principle and keeping the length unchanged; adjusting the angle of each rectangular pouring gate to enable the side length of each rectangular pouring gate to be parallel to the X axis or the Y axis in the reference coordinate system; and establishing a rectangular rubber runner entity at the rectangular pouring gate, importing the three-dimensionalentity assembly model into vulcanization simulation software in a conversion format to perform filling analysis, exporting a calculation result, and performing subsequent processing to obtain the total weight of each layer of
