Railway plum blossom type bearing platform digital twin internal force simulation calculation method

Abstract

The application discloses a kind of railway plum-shaped bearing platform digital twinborn internal force simulation calculation methods, comprising the following steps: input the outer contour size information of railway plum-shaped bearing platform;Establish the digital twinborn internal force simulation calculation model architecture corresponding to plum-shaped entity physical bearing platform;To the digital twinborn model architecture constructed, give model size;To the digital twinborn model architecture constructed, give unit characteristics;The overall stiffness matrix and load array of bearing platform digital twinborn model are composed.The application builds the digital twinborn model architecture of high-precision simulation entity plum-shaped bearing platform internal force characteristics, and gives digital twinborn model geometric information, elastic modulus and the like parameters, and using space beam element stiffness matrix simulates each tensile rod and compression rod contained in digital twinborn model, gives unit attribute, and then establishes the digital twinborn model of railway plum-shaped bearing platform.The application solves the problem of accuracy and autonomy direction of railway plum-shaped bearing platform digital twinborn model.
