The invention discloses a maintenance step simulation method based on model fusion, and relates to the technical field of virtual maintenance. According to the method, a high-fidelity multi-physics field simulation environment is constructed by deeply fusing a three-dimensional geometric model with physical attributes such as density and friction coefficient and assembly logic; an obstacle avoidance path is planned by using a fast expansion random tree algorithm, and real-time calculation of the deformation of the flexible pipeline and the statics equilibrium state of parts is realized in combination with a mass spring model and a polyhedral friction cone theory. On the basis, a multi-dimensional evaluation system containing space gaps, view shielding and operation torque weights is constructed, feasibility confidence indexes of overhaul steps are quantitatively evaluated, and a virtual guide potential field and directed acyclic graph logic verification are assisted, so that an overhaul guide file conforming to physical rules and process specifications is finally and automatically generated. The problems that traditional simulation lacks mechanical verification and flexible body simulation is distorted are effectively solved, and the reliability of maintenance process design is remarkably improved.
