Abstract

The article presented an improved visibility evaluation model to make up two shortcomings of the visual cone maintenance visibility analysis method based on the real visual field, which could not quantitatively evaluate visibility and visual field occlusion. Firstly, combining sight distance and volume, we determined the position of objects in-plane field of vision. Then the line of sight model from human eyes to each part of the object was established to determine the occlusion of each part of the object. Finally, the evaluation results were quantified. The redevelop of DELMIA software realized the improved maintenance visibility analysis function module. In the maintenance visibility verification of the welding workstation, the improved method can effectively evaluate the visibility and quantify the evaluation results and quantitatively evaluate the occlusion of objects. The improved method greatly improved the comprehensiveness and rationality of visibility analysis in complex equipment maintenance.
