DELMIA-based emulational engineering practice method of cable maintenance

Abstract

The invention provides a DELMIA-based emulational engineering practice method of cable maintenance. The method includes the steps that cable information and space relation are determined; a virtual maintenance environment is built on a DELMIA-based emulational platform; a disassembly path of a cable connector is designed, and movement actions of the cable connector are built; different control points are set on a cable module along the disassembly path of the cable connector to achieve flexible movement of a cable; the movement locus that a hand grabs the connector is planed, and maintenance actions of the hand of the human body are built; emulation is processed by segments to achieve space-time synchronization of the cable connector, the cable and a human body model. According to the DELMIA-based emulational engineering practice method of cable maintenance, the limitation that in a traditional virtual assembly process, a flexible part is considered as a rigid body, the flexible body of the cable cannot be showed up, and the interactive operation emulation of the flexible body can not be conducted is broken through, simulation of complex movement of the cable is achieved, the problems existing in the cable in the maintenance process can be found, and improvement of the maintenance design of the cable is facilitated.

Description

technical field [0001] The invention belongs to the technical field of virtual reality technology auxiliary system maintenance, and in particular relates to an engineering practice method of cable maintenance simulation based on DELMIA. Background technique [0002] Cables are the most important type of components in electromechanical systems such as aircraft, missiles, ships, and automobiles. According to statistics, the failure rate of cable components accounts for 20% of the total failure rate. In actual engineering, many products contain a large number of cable assemblies. For example, in some electrical equipment compartments, a large number of cables can be seen. The wiring of these cables is very complicated, and the quality of its design directly affects the quality of the entire product. Especially for complex equipment systems, it is necessary to bring the electrical wiring design into its design considerations in the early stage of development, but there has been ...

AI Technical Summary

Problems solved by technology

[0004] However, the simulation of flexible cables in the virtual environment is more complicated than that of rigid bodies, and the movement also has great uncertainty.

At present, in the virtual simulation environment, digital prototypes often only have 3D models of rigid bodies, but cannot represent flexible bodies such as cables, let alone perform interactive simulation operations on flexible bodies such as cables.

In this way, the obtained simulation results often cannot produce a good guiding effect on the actual operation.
