Abstract

The invention discloses an immersive virtual simulation-based repairability dynamic assessment method. The method is characterized by comprising the steps of simulating a repair activity in an immersive virtual environment; performing dynamic assessment and verification on a repairability design level of a product; calculating a repairability quantitative index conformity status and verifying whether a repairability qualitative requirement is met or not according to data obtained by verification; and verifying whether the repairability meets an index requirement or not through comprehensive tradeoff. According to the method, repairability design assessment is performed by utilizing a virtual repair technology, and the product and a repair process do not need to be realized physically, so that the deficiencies of long manufacturing cycle, high cost and difficult modification and update of a physical prototype are overcome. The researched helicopter virtual repair technology is an important development direction of helicopter repairability design nowadays, and basic methods and ideas of research have a certain reference value for carrying out the helicopter repairability design.

Description

technical field [0001] The invention belongs to the technical field of aircraft maintenance support, and in particular relates to a maintainability dynamic evaluation method based on immersive virtual simulation. Background technique [0002] Helicopter is a special aircraft with high maneuverability. It can take off and land vertically, fly close to the ground, hover in the air, fly sideways and retreat, which is impossible for ordinary fixed-wing aircraft. There is a great potential market in the national economy and national defense construction, and can be widely used in short-distance transportation, disaster relief, aerial photography, fire extinguishing, maritime search and rescue, and chasing fugitives. In the military, it can be used for transportation, tactical support, reconnaissance, communication command, and rescue. With the gradual opening of the country's low-altitude airspace, helicopters will lead to a "blowout" development stage. [0003] Helicopter deve...
