Embodiment Construction
[0031] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings.
[0032] A digital model-based regional security analysis method, the flow chart is shown in figure 1 , according to the following steps, including:
[0033] Step 1: Visual division of aircraft areas:
[0034] First of all, on the basis of the 3D design model of the initial prototype of the aircraft, the aircraft is divided into regions according to the principle of regional division. The principles of area division include division with reference to aircraft compartments, division according to aircraft composition interface, and division according to inspection and maintenance requirements, and area division has the following characteristics:
[0035] a) The area division should be concise;
[0036] b) Each area should be divided as far as possible according to the actual tangible margin;
[0037] c) The size of the area should allow ca...

The invention relates to the field of airplane design, and specifically to a digital model based region security analysis method. The analysis method comprises the following steps: step 1, performing visual partition on airplane regions; step 2, establishing a region equipment set; step 3, establishing an electronic model machine; step 4, making region security criteria; and step 5, performing region security analysis. According to the digital model based region security analysis method, the dangerous sources are integrated into the product model in the digital mode, so that the dangerous factors for the airplane can be found vividly in time in designing the airplane so as to take security measures; and the region security criteria are embedded in a software for realizing the automatic region security analysis and examination on each region of the airplane so as to find possible-occurring unsafe factors and to make an item list with potential safety hazards, and the parts with the potential safety hazards are improved, so that the analysis method has the advantages that the time loss caused by the later design changing is avoided, the design period for the airplane is effectively shortened, the working efficiency is improved, the analysis method is high in operability, and the like.
Description
technical field [0001] The invention relates to the field of aviation product design, in particular to a digital model-based regional safety analysis method. Background technique [0002] Zonal Safety Analysis (ZSA), as an important content of system safety analysis, was first seen in Douglas Aircraft Company abroad, and then other airlines such as Airbus also established corresponding regional safety analysis procedures. European and American aviation industry departments and civil aviation management departments have formulated a series of top-level documents such as "SAEARP4754 Civil Aircraft and System Development Guidelines", "FAA System Safety Manual", "FAA System Safety Management Outline", among which "SAEARP4761 Civil Airborne System The area safety analysis method is proposed in "Guidelines and methods for the safety assessment process of equipment and equipment". [0003] In terms of regional security analysis and research, domestic research is relatively weak. ...
