Abstract
To ensure products with high reliability and quality, maintainability design and verification is an integral part of design process.
As a crucial factor in maintainability design, visibility evaluation is the most important part of maintainability design and verification. However, subjective and expert judgment in evaluation methods are the two major problems limiting the development and application of the visibility design. To solve these problems, this paper proposes a visibility automation analysis and evaluation model based on virtual maintenance. Firstly, two sub-evaluation indicators are designed for visual ability and visual obstruction. Secondly, in responds to the two indicators, two models are established based on visual cone and feature points respectively. Moreover, a comprehensive visual accessibility evaluation model based on line-of-sight interference detection and two models is developed. Finally, a case of an engine coupling fastening bolt visibility assessment is conducted and verifies the effectiveness of the proposed method.
