[Abstract]:To ensure that the product has good maintainability, need to fully consider the factors of maintenance personnel to carry out the design. One potential field is a kind of relationship between reference model describes the concept for potential field establishment, can be more intuitive for Master surface distribution of elements in space, can be used to improve the quality and efficiency of maintainability design. Aiming at the target the reachability degree problem maintenance in the process of operation, set up the accessibility potential function and proves its basic properties, and simulation analysis and example verification. The main contents of this thesis include: 1. the basic theory and analysis the situation description field. In the concept of artificial potential field, analyzing the construction method the basic theory and system, the electrostatic field from the classical field theory, introducing potential field concept is used to describe the human factor influence on the maintenance design, the establishment of the situation A basic framework, and analyzes the basic principle of.2. potential field to establish a mathematical model of potential field can reach, and complete the proof. Reference for conservative design theory about the working space in the project, effects of accessibility factors and influence mechanism, established the mathematical model of potential field up to the basic properties of the reachability analysis. One potential field, on the conservation theory. To expound and prove the related human arm as the research object, established the accessibility of people because of potential field function and the visual simulation analysis and experimental verification of.3. on the potential energy distribution of space will be applied to the people because of potential field maintenance layout optimization, verify the validity of the theory. Based on the accessibility of people according to field maintainability visualization layout optimization design method and optimization design based on layout of maintainability accessibility model Method to aircraft actuator. Equipment for the application case, the layout optimization simulation, and carried out experiments. The results show that the accessibility of people because of potential field can be effectively applied to the maintenance of layout optimization design.
