Embodiment Construction

[0031] The following describes the embodiment of the present invention in detail from the two aspects of MBD model construction and multi-Agent collaborative workflow implementation.

[0032] Construct MBD model of aircraft component tooling

[0033] The collaborative tooling MBD tooling model consists of tooling parts, tooling components, characteristics, annotations and attributes. The tooling components can be divided into main geometry, auxiliary geometry, reference geometry, features, annotations, and attributes, which can be expressed by the following formula:

[0034]

[0035] Among them, M t represents the tooling MBD model (t=1, 2,...); G i represents the geometric feature elements in the MBD model; C j represents the characteristic information in the MBD model; A k represents the annotation information in the MBD model; P z represents the attribute information in the MBD model.

[0036] The geometric feature elements G i in the model include main geometric elemen...

Abstract

The invention belongs to the field of aircraft design digitization, and relates to an MBD-based aircraft complex structural part collaborative design implementation method which comprises the steps: firstly constructing an aircraft structural part tool MBD model; and then completing tool MBD model design through a multi-Agent cooperative workflow. Multi-Agent technical design is adopted, and collaborative design of the aircraft structural parts is completed through the collaborative workflow so that the requirement for rapid and accurate design collaboration of the aircraft complex structuralparts is met, wherein the Agent refers to the working entity which stays in a certain environment and can continue to function autonomously and has the characteristics of residence, reactivity, sociality, initiative and the like; the principle of the multi-Agent (MAS) technology is that the multi-Agent technology is composed of a plurality of Agents, and the Agents cooperate with one another to complete a common global target, and all the Agents coordinate and collaborate and share knowledge and resources and finally achieve collaboration.

Description

technical field [0001] The invention belongs to the field of aircraft design digitization, and in particular relates to an MBD-based collaborative design realization method for aircraft complex structural parts. Background technique [0002] With the transformation of aviation airborne products to multi-variety and small-batch production methods. The development and production of aircraft structural parts are faced with many constraints such as high tooling quality requirements, low development costs, and short research and development cycles. Therefore, in the design process of aircraft component tooling, the manufacturing and assembly process of the product and the rigidity of the tooling must be considered comprehensively. Due to many factors such as strength and product assembly stress, tooling designers cannot complete the complex work of tooling design alone, and must cooperate with product technology, quality, assembly simulation and inspection staff to complete produ...
