Abstract: The embodiments of the present disclosure provide a physical digital twin modeling method and apparatus for an assembly, an electronic device and a medium. The physical digital twin modeling method for the assembly includes: generating a geometric distribution error surface of an assembly surface of a part; establishing an ideal model of the part without the geometric distribution error surface; integrating the geometric distribution error surface with the ideal model to establish a geometric distribution error integrated model of the part; assembling the geometric distribution error integrated model on a computer to establish a geometric digital twin model; and adding physical conditions to the geometric digital twin model of the assembly to establish a physical digital twin model of the assembly.
