The invention discloses an automatic accessibility evaluation method and system for maintenance equipment. The evaluation method comprises the steps of obtaining the virtual arm data and the virtual maintenance object data; extracting a first virtual maintenance object feature point based on an adjacent point normal vector included angle feature point extraction algorithm according to the virtualmaintenance object data; extracting a second virtual maintenance object feature point based on a vertex saliency feature point extraction algorithm according to the virtual maintenance object data; constructing a virtual arm kinematics model according to the virtual arm data; determining a reachable domain of the tail end of the virtual arm or the tail end of the maintenance tool according to thevirtual arm kinematics model; performing spatial division on the reachable domain, and determining a feature point set; and determining a reachability evaluation result of the maintenance equipment according to the first virtual maintenance object feature point, the second virtual maintenance object feature point and the feature point set. According to the evaluation method and system provided bythe invention, the accessibility evaluation result of the maintenance equipment can be automatically determined, and the accuracy of the accessibility evaluation result is improved.
Description
technical field [0001] The invention relates to the field of maintenance operations, in particular to a method and system for automatically assessing the accessibility of maintenance equipment. Background technique [0002] In order to ensure that the equipment has good service reliability and low life-cycle cost, maintainability design and verification has become an indispensable research field in the equipment design process. In the virtual maintenance environment, the maintenance process of equipment can be simulated. At the same time, a large amount of data generated during the simulation process can provide strong support for the analysis and evaluation of equipment maintenance accessibility, maintenance time, maintenance safety, etc., and discover the aspects of equipment maintainability design in advance. The deficiencies, and suggestions for improvement, etc., will solve potential problems related to product maintainability at an early stage of the design stage. Acc...
