For some complex mechanical equipment,design profile determine s its maintenance performance.It will result in huge difficulties in the latter maintenance if the equipment without good maintainability.As the main force of the national marine warfare,armored vehicles is a special large-scale machinery and has higher requirements on the maintainability.The traditional equipment maintenance design analysis and evaluation depends on the physical prototype or full-size model a lot.But the physical prototype or full-size model usually created after design has been finalized.It leads to the disjo int between the design and evaluation.With the development of virtual maintenance technology,it makes do maintenance evaluation in the design stage possible.Due to the application of new technology,it also brings about the change of the procedure and method of equipment maintenance evaluation.Based on the requirements of specific projects,this paper studies the maintainability of armored vehicles with virtual maintenance technology.First of all,the paper summarizes the factors affecting the maintain ability of armored vehicles and establishes a set of evaluation index system.Based on the evaluation system and the characteristics of virtual maintenance technology,this paper use armored vehicle maintenance checklist,the cube model and MTM-UAS to predicting and analyzing each maintainability index.Then,this paper proposes a comprehensive evaluation algorithms based on the cloud model.Finally,this paper develops a maintenance evaluation module based on the Make Real3 D VSP virtual reality simulation p latform.This module integrates the evaluation index system and evaluation criteria of armored vehicles and the related algorithms based on the theoretical research through the paper.It provides a convenient and reliable tool for designers to evaluate the maintainability of armored vehicles in the early design process and helps to improve the maintainability of armored vehicles.In addition,it provides a reference method for the application of virtual maintenance technology in the field of equipment maint enance evaluation. |
