Embodiment Construction

[0040]Drawing on the concept of kinetic elements in human factors engineering, the present invention proposes the concept of maintenance therblig, and defines it as "the basic action unit that constitutes a maintenance action", that is, common maintenance actions can be performed by a certain amount of maintenance therblig. Composition of kinetic elements; different maintenance kinetic elements can be combined into different maintenance actions; at the same time, maintenance kinetic elements have a certain generality, which is the encapsulation of human low-level movement and action control functions. Develop the corresponding basic action function library based on the maintenance kinetic elements, and obtain different maintenance action simulations by giving different parameters to the action functions, and complete the virtual simulation of the entire maintenance process through a series of maintenance action simulations. In this way, the user's workload can be greatly reduce...

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...
