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.

The invention provides a fruit picking method and device, computer equipment and a storage medium, and belongs to the field of agricultural picking. The method comprises the steps that under the condition that a clamping jaw picks fruits, magnetic field changes in the fruit contact process are obtained in real time, and three-dimensional contact force is determined through a pre-established mapping relation model from external force to magnetic field signals; based on the three-dimensional contact force, the maturity and the contact state of the fruits are estimated through a pre-established multi-field collaborative mapping model, and the multi-field collaborative mapping model comprises a viscoelastic contact mechanical model, a friction cone model and a damage energy model; according to the estimated maturity and the contact state, the clamping force compensation amount is calculated in combination with priori clamping force estimation and tactile feedback; the current clamping force of the clamping jaw is adjusted in real time based on the clamping force compensation amount, and stable grabbing and picking of fruits are achieved. Therefore, when the clamping jaws slightly slide or the softness changes, the force can be rapidly and smoothly adjusted, and stable grabbing and lossless picking are achieved.
