Method for establishing maintenance therblig set supporting virtual maintenance simulation

Abstract

The invention discloses a method for establishing a maintenance therblig set supporting virtual maintenance simulation. The method comprises the following steps of: encapsulating a control function for a low-level movement and an action of a person so as to form a plurality of maintenance therbligs which can simulate a basic action unit of a maintenance action; and establishing a corresponding basic action function library based on the maintenance therbligs. In the method, the maintenance action is divided into moving actions and operating actions, wherein the moving actions comprise two therbligs of human movement and posture adjustment; the operating actions comprise two types of unarmed operation and tool using operation; the unarmed operation comprises three therbligs of grasping, disassembly and assembly operation, and releasing; and the tool using operation comprises four therbligs of tool using, positioning, placing an object and holding. Due to the adoption of the method, work load of a user can be reduced; requirements on the user are reduced; and virtual maintenance simulation efficiency is greatly improved.

Description

technical field [0001] The invention relates to a virtual maintenance simulation method, in particular to a method of decomposing the maintenance process into a combination of finite set elements and establishing a function library based on the finite set, which belongs to the technical field of data processing. Background technique [0002] Virtual Maintenance Simulation (Virtual Maintenance Simulation, VMS) is the application of virtual reality technology in the field of maintenance. It refers to the simulation of the actual maintenance process of products in a virtual environment that integrates models, simulations and simulators. The virtual maintenance simulation is the core of the virtual maintenance training system. The degree of reality of the simulation and the interactive convenience of the control directly affect and determine the effect of the maintenance training. Virtual maintenance simulation is the reproduction of the actual maintenance process and maintenanc...

[0021] To sum up, the existing human motion classification methods are often proposed for their own unique purposes, and cannot be directly used for virtual maintenance simulation.

There is currently no action model set specifically for maintenance actions or virtual maintenance simulations
