Embodiment

[0048] Taking an electrical control device in an aircraft equipment compartment as an example, the electrical control device is used to provide power for other electrical equipment. The device is located in the front section of the equipment compartment close to the warhead, and the other equipment connected to it are distributed in different ways, and these electrical equipment have their own electrical interfaces, which are connected to the electrical control device through electrical connectors (cable joints and intermediate connectors). disconnect.

[0049] Carry out the wiring requirement analysis around the electrical control device in the equipment compartment, and clarify the equipment connected to it and the corresponding connection method. The schematic diagram of the cable connection of the electrical control device is as follows: Figure 7 The corresponding cable connections are shown in Table 1.

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 ...
