Problems solved by technology

Technicians need to spend a lot of time and energy looking for missing items and unreasonable parts in assembly instructions when performing heavy and repetitive tasks, which is time-consuming and labor-intensive
[0005] (2) Excessive reliance on the experience of craftsmen
If the knowledge level of the craftsmen is insufficient, it is difficult to find detailed problems. On the one hand, the generated assembly instructions are different, and on the other hand, the loss of experience and knowledge caused by personnel flow cannot be effectively avoided.

Embodiment

[0046] Embodiment: This embodiment takes the process number in the assembly instruction as the object, and the specific steps are as follows:

[0047] 1. It is concluded from the process documents obtained through research that: the process number in the assembly instruction cannot be empty, if it is empty, it violates the rules of content integrity. In addition, the process number starts with 10 and is incremented sequentially, and cannot be repeated or missing. When a process needs to be added, the principle of symmetrical compromise is adopted to insert the process number. If the above conditions are not met, there is a logical contradiction.

[0048] 2. Form the above summary into two pieces of assembly process design rule knowledge, and make a production framework representation, as shown in Table 2 below.

Abstract

The invention discloses an aircraft assembly process design rule knowledge management method and system, and relates to the technical field of digital assembly, and the method comprises the steps: firstly, obtaining assembly process design rule knowledge related to aircraft assembly instruction verification; secondly, performing generative framework representation and reasonable classification andattribute definition according to the characteristics of knowledge; and finally, designing a knowledge storage form, and associating the assembly process design rule knowledge object with the classification structure for knowledge classification and storage, thereby forming an assembly process design rule base. The system comprises a data layer, a logic layer and an application layer. And the data layer provides data related to the assembly process design rule to the logic layer. And the logic layer processes the rule data source and provides the processed rule data source for the applicationlayer in different data views. And the application layer formulates different application modes oriented to different roles for the data formed by the logic layer, so that the technicians are assisted in checking the assembly instruction.

Description

technical field [0001] The invention relates to the technical field of digital assembly, in particular to a method and system for knowledge management of aircraft assembly process design rules. Background technique [0002] The assembly instruction is to specify the complete technological process of the production management unit and the control requirements of each link of the process and to record the quality records in the production process. During the aircraft assembly process, a large number of assembly instructions are needed to guide the assembly work. The rational preparation of assembly instructions has an important impact on improving assembly quality and shortening the manufacturing cycle. Therefore, there are strict approval and execution procedures after assembly instructions are compiled. [0003] Nowadays, aircraft are generally designed for remodeling. Technicians will modify parameters based on the assembly instructions of the original model when preparing ...
