Embodiment Construction

[0043] Now given as figure 1 The overall assembly risk factors and levels of the final assembly of the aircraft are shown. Based on this figure, the specific implementation method of the risk assessment of the assembly plan will be described in detail below. See Figure 7 , the present invention is a method for risk assessment of aircraft assembly process, the specific steps of the method are as follows:

[0044] Step 1: Obtain the 3D digital model of the product to be assembled, the required tooling, and the assembly scene from the design department, and use DELMIA software to create a simulated PROCESS file, and import the tooling and assembly scene model into the resource list of the PROCESS file structure tree. The assembly product model is imported into the productlist of the PROCESS file structure tree, and at the same time, it is arranged in the scene of the actual assembly according to the plan, and the corresponding 3D model is arranged in the assembly scene in DELMI...

Abstract

The invention provides an aircraft assembling process risk evaluation method, which comprises six major steps that 1, a three-dimensional digital model corresponding to an assembly body, a tooling and an assembling scene is imported by using DELMIA, a corresponding process file is created, and integral scheme influence factors and hierarchy diagrams are obtained; 2, the transportation risk of the assembling scheme is subjected to influence factor and hierarchy analysis to obtain the influence factors and the hierarchy diagrams, and a hierarchy analysis method is used for analyzing the influence weight of each influence factor on the risk generating possibility; 3, the field risk influence factor of the assembling scheme and the hierarchy are analyzed to obtain the influence factors and the hierarchy diagrams; 4, the whole assembling simulation flow process is created in the corresponding process file of the DELMIA software according to the given assembling scheme; 5 the weight coefficient of the influence factor after the integral assembly scheme risk generation is obtained by using the hierarchy analysis method; 6, the second index assembling scheme risk degree overlap of the integral evaluation of the assembling scheme is calculated.

Description

technical field [0001] The invention relates to a method for risk assessment of an aircraft assembly process, specifically a method for calculating the risk degree in an aircraft assembly process based on aircraft assembly simulation, which belongs to the technical field of aircraft assembly and is used to solve the problem of assembly in the process of aircraft assembly process design. Process technicians can quickly grasp the risks of aircraft assembly to improve the quality and efficiency of aircraft assembly. Background technique [0002] The risk in the aircraft assembly process specifically refers to the potential problems that may endanger the assembly plan. It is the measure that the assembly goal cannot be achieved under the determined assembly funds, assembly progress and technical constraints. It consists of three parts: the root cause of the risk, that is, the risk the cause or risk of risk; the probability or likelihood that a particular result will not be produ...
