Description

Technical Field

[0001] The present invention relates to the technical field of aircraft process design, and particularly to a method for constructing aircraft assembly instructions. Background Art

[0002] The development cycle of aircraft products is long, the multi-disciplinary collaboration is strong, and the product data is changed frequently. In addition, the aircraft manufacturing process strictly implements the requirements of manufacturing and design compliance. Process design needs to accurately implement the design status and changes to ensure the controllability of the aircraft development status and the safety of flight test. Assembly instructions are the most direct production process documents for guiding the assembly of aircraft until the formation of an aircraft. There are various forms of existing assembly instruction process compilation:

[0003] First, process personnel manually compile the instructions, file them in the reference room after completion. The planning personnel borrow and copy them from the reference room as needed and then put them into on-site use. When there is a change, the process personnel upgrade the assembly instructions in the reference room and issue instruction change sheets for the assembly instructions in production execution. This method has low work efficiency, high error rate, and it is difficult to ensure the integrity of the assembly instructions.

[0004] Second method, apply process CAPP software, corresponding to design drawings and digital models, compile assembly instructions and assembly instruction lists according to the validity of the drawings and digital models (the list is managed according to the validity of each flight, and an assembly instruction list needs to be compiled for each production flight). After approval, it is pushed to the ERP system. The ERP system extracts the corresponding assembly instructions according to the assembly instruction list, and the planner configures the production plan requirements and issues them for execution. When there is a change, a series of instructions need to be changed corresponding to the validity of the drawing and digital model changes, and instruction change sheets are issued for the instructions in on-site execution, and the assembly instruction list is also changed. This method requires constant management of the validity of the assembly instructions. There is a situation where the work of one drawing, digital model or one design configuration module is completed by multiple assembly instructions, and there is also a situation where one assembly instruction completes the work of multiple drawings, digital models or modules. When a change occurs, it is necessary to trace multiple assembly instructions and assembly instruction lists for changes, resulting in low management work efficiency and prone to errors and omissions.

[0005] The third method is to apply product PLM software, corresponding to the design configuration module, compile assembly instructions, and after the instructions are approved, receive the design configuration configuration sheet. The system assists in compiling an assembly instruction list for the corresponding configuration configuration sheet (the assembly instruction list is also managed according to the effectiveness of a single batch), extract the corresponding assembly instructions according to the assembly instruction list, and the planner configures the production plan requirements and issues them for execution. When changes are made, the corresponding assembly instructions need to be upgraded according to the changes in the design configuration module, and the on-site assembly instructions and assembly instruction lists need to be changed. Although this method does not directly manage the effectiveness of assembly instructions, there is still a situation where the work of one module is completed by multiple assembly instructions, and there is also a single assembly instruction that completes the work of multiple modules. When changes occur, it is necessary to trace back multiple assembly instructions and assembly instruction lists for changes, and the management efficiency is low.

[0006] Based on the above situation, in view of the complexity of aircraft manufacturing, the development cycle and the high requirements for product quality, it is necessary to find a method for constructing aircraft assembly instructions that can not only ensure the conformity of process design and product design (thereby ensuring the conformity of manufacturing and design), but also shorten the human control path as much as possible, reduce human intervention work, avoid human errors, reduce the repetition of process personnel, and improve work efficiency. Summary of the invention

[0007] The purpose of this application is to provide a method for constructing aircraft assembly instructions to reduce repetition and human errors of process personnel and improve the efficiency and quality of assembly instruction construction and management.

[0008] Technical Solution

[0009] A method for constructing aircraft assembly instructions comprises the following steps: compiling source assembly instructions, specific assembly instructions and an assembly instruction list according to an aircraft design module and a corresponding process plan to form a process design instruction file library; proposing an aircraft sortie design module configuration sheet according to the design module and the production sortie; extracting valid source assembly instructions and valid specific assembly instructions corresponding to the aircraft sortie from the process design instruction library according to the design module configuration sheet and the production sortie, and forming an aircraft sortie production execution assembly instruction file with the source assembly instructions, the valid specific assembly instructions and the assembly instruction list.

[0010] The method for constructing aircraft assembly instructions is characterized by comprising the following contents:

[0011] 1) The process design instruction file library includes multiple assembly units, and the assembly units are designed in a serial and parallel relationship according to a "parent-child pair" relationship, and each assembly unit serves as a parent node of a set of assembly instructions.

[0012] 2) All parts, components, subassemblies, outsourced finished products, standard parts, and consumables contained in the aircraft design module are divided and matched under corresponding assembly instructions to form source assembly instructions based on the aircraft design module;

[0013] 3) Supplement the source assembly instructions according to the requirements of the process plan to form specific assembly instructions. These specific assembly instructions are not allowed to consume the data of the aircraft design module and define the validity matching the effective batch of the aircraft design module.

[0014] 4) Plan all the assembly instruction items for each assembly unit, including the source assembly instructions and the specific assembly instructions. Among them, each source assembly instruction can consume at most one aircraft design module in a supporting manner. Multiple source assembly instructions are allowed to consume one aircraft design module in a supporting manner, and one source assembly instruction is not allowed to consume multiple aircraft design modules in a supporting manner. The validity of the source assembly instruction is the same as that of the aircraft design module. Each specific assembly instruction is not allowed to consume the supporting aircraft design module, and its validity is defined by the process personnel when compiling the instruction.

[0015] 5) Compile the assembly instruction list of the aircraft according to the source assembly instructions and the specific assembly instructions. The assembly instruction list only reflects the serial and parallel relationships of the assembly instructions of the aircraft and is used to specify the implementation order of the assembly instructions. The aircraft assembly instruction process design library is composed of the source assembly instructions, the specific assembly instructions and the assembly instruction list.

[0016] 6) Put forward the aircraft design module configuration list that can match the production demand flight number. The information system automatically matches and generates the effective assembly instructions of the aircraft required for the corresponding aircraft flight number according to the design module configuration list, the production flight number and the aircraft assembly instruction process design library corresponding to the aircraft flight number, including the source assembly instructions and the specific assembly instructions, and forms the production execution assembly instruction file for the corresponding aircraft flight number for production execution, including the effective source assembly instructions, the effective specific assembly instructions and the assembly instruction list.

[0017] The source assembly instructions are only subjected to process design according to the design module they consume, and there is no need to define their validity. The source assembly instructions contain the supported part types and part numbers and the associated aircraft design modules. The source assembly instructions contain the basic information of the corresponding design module and have a unique association relationship with the design module.

[0018] The specific assembly instructions are constructed according to the requirements of the process plan, and their validity is directly given by the process design and matches the production demand validity.

[0019] Compared with the traditional technology, the present invention has the following effects:

[0020] 1) The present invention divides the assembly instructions into two types: source assembly instructions and specific assembly instructions. The source assembly instructions have a unique correspondence with the aircraft design module. The process does not need to pay attention to the effectiveness of the design module and does not need to change the source assembly instructions with the change of the effectiveness of the design module. The specific assembly instructions are completely independent of the aircraft design module, and their effectiveness is defined by the process according to the process plan, with universality and uniqueness, and does not change with the change of the design module, greatly reducing the work of the process to frequently change the assembly instructions with the change of the design effectiveness.

[0021] 2) The present invention designs a design module configuration list, which matches the aircraft flight requirements. Only the effective design modules are maintained according to the design module configuration list, which can be given by the design or by the process personnel according to the effectiveness of the design module, with the convenience of flexible work.

[0022] 3) The information system extracts and generates the effective source assembly instructions that match the production flight according to the design module configuration list of the present invention, without the process personnel maintaining the effectiveness of the source assembly instructions, improving the application efficiency of the assembly instructions and reducing human errors.

[0023] 4) The present invention designs an assembly instruction list, which only stipulates the serial and parallel relationships of the assembly instructions. Only the assembly instructions need to be incrementally maintained, without defining their effectiveness or paying attention to the production requirements, simplifying the management path of the process design and improving the application efficiency of the documents.

[0024] The following further elaborates on the present application in conjunction with the accompanying drawings of the embodiments. Description of the Drawings

[0030] This implementation case focuses on the compilation and management of aircraft assembly instructions: assembly instructions are prepared based on the aircraft design module and process plan to form a process design instruction library, and a production instruction assembly instruction database is formed through logical calculation and extraction based on the design module and production batches. First, source assembly instructions and specific assembly instructions are prepared, and an assembly instruction list is compiled for all assembly instructions. The source assembly instructions, specific assembly instructions, and assembly instruction list form the data of the process design instruction library. Second, a design module list is compiled to propose effective design modules that can match the production demand batches. When the production demand batch is determined, the information system automatically matches the corresponding effective source assembly instructions and specific assembly instructions for the production batch, and together with the assembly instruction list, it forms the production execution assembly instruction file data for production execution. The logical relationship between the process design instruction library and the production execution assembly instruction is as Figure 1 shown.

[0031] The specific approach is as follows:

[0032] In this embodiment, the top cover of a module among multiple aircraft design modules of the MA800 aircraft is used as an assembly unit to further elaborate on the present invention. According to the aircraft design module and process plan, the top-level structure of the aircraft assembly instruction process design library is built, forming multiple assembly units, and the serial and parallel relationships of each assembly unit are designed according to the "parent-child pair" relationship. Each assembly unit serves as the parent node of a set of assembly instructions;

[0033] First, obtain the data of the top cover design module DM_MA800-5410-3100-001 of the MA800 aircraft design. The composition of the MA800 top cover design module is shown in Figure 2 shown.

[0034] Plan and design the top-level structure of the MA800 aircraft top cover assembly and conduct assembly instruction design: Analyze the design module data, combine it with the process plan, and plan the top-level structure of the assembly to form three assembly units: MA800-5410-31110-001-981, MA800-5410-3100-001-981, and MA800-5410-3100-001-982.

[0035] All three assembly units are in a serial relationship, and the execution order is MA800-5410-31110-001-981, MA800-5410-3100-001-981, and MA800-5410-3100-001-982 in sequence.

[0036] All the parts, components, sub-assemblies, off-the-shelf finished products, standard parts, and consumables included in the aircraft design module are allocated and matched under the corresponding assembly instructions, and the aircraft design module is synchronously associated to form source assembly instructions based on the aircraft design module. This type of assembly instruction only conducts process design according to the consumed design module and does not need to define its validity. The matching content included in the source assembly instruction has the matching part numbers, types, and the aircraft design module numbers associated with the part numbers. The aircraft design is divided into multiple aircraft design modules, each design module has a fixed and unique number, and the source assembly instruction also has a fixed and unique number. Coupled with the fact that only one aircraft design module can be uniquely associated in the source assembly instruction, a specific association relationship is thus generated between the source assembly instruction and the aircraft design module. Based on the requirements of the process plan, the source assembly instruction is supplemented to form a specific assembly instruction. This specific assembly instruction is not allowed to consume aircraft design module data and executes the validity matching the effective flight times of the aircraft design module;

[0037] In the embodiment, the assembly instruction items planned for each assembly unit are respectively:

[0038] AO_MA800-5410-31110-001-981-100, and the corresponding assembly unit is:

[0039] MA800-5410-31110-001-981; AO_MA800-5410-3100-001-981-100, AO_MA800-5410-3100-001-981-200, and the corresponding assembly unit is:

[0040] MA800-5410-3100-001-981; AO_MA800-5410-3100-001-982-100, and the corresponding assembly unit is MA800-5410-3100-001-982, and the assembly instruction matching is divided by consumption. Among them, AO_MA800-5410-31110-001-981-100, AO_MA800-5410-3100-001-981-100, and AO_MA800-5410-3100-001-981-200 jointly consume and match the parts, components, and standard parts in DM_MA800-5410-3100-001 to form a complete set of source assembly instructions (without specifying the effective flight times) corresponding to this module. AO_MA800-5410-3100-001-982-100 has nothing to do with the design module and is a specific assembly instruction, and the defined flight time validity is 10101-19999, as Figure 3 shown.

[0041] Compile the aircraft assembly instruction list according to the source assembly instructions and specific assembly instructions. The assembly instruction list only reflects the serial and parallel relationships of the aircraft assembly instructions and is used to specify the implementation order of the assembly instructions. The aircraft assembly instruction process design library consists of the source assembly instructions, specific assembly instructions, and the assembly instruction list.

[0042] Based on the approved assembly instructions, compile the MA800 top cover assembly instruction list according to the product assembly process plan, as Figure 4 shown, which only reflects the serial and parallel relationships of the assembly instruction items and assembly instructions (the serial relationship is represented by sequential numbers, and the parallel relationship is represented by the same number), and does not reflect the effectiveness of the flight number. The specific execution order is as follows:

[0043] AO_MA800-5410-31110-001-981-100, AO_MA800-5410-3100-001-981-100, AO_MA800-5410-3100-001-981-200, AO_MA800-5410-3100-001-982-100, where AO_MA800-5410-3100-001-981-100 and AO_MA800-5410-3100-001-981-200 are parallel processes and allow synchronous execution. So far, the source assembly instructions, specific assembly instructions, and assembly instruction list of the MA800 top cover form the assembly instruction design library for the top cover.

[0048] AO_MA800-5410-3100-001-982-100 3 MA800-5410-3100-001-982.

[0049] According to production requirements, an aircraft flight design module configuration list that can match the number of flight sorties required for production is proposed. The configuration list is compiled and distributed to configure the effectiveness of the top cover of aircraft No. 10101 of the MA800 aircraft for subsequent response to production requests. The information system retrieves the available top cover design module DM_MA800-5410-3100-001 from the aircraft design module configuration list of aircraft No. 10101, and then matches the relevant source assembly instructions for the effective top cover of aircraft No. 10101 of the MA800 aircraft through DM_MA800-5410-3100-001 to form the production execution source assembly instructions for the top cover of aircraft No. 10101. The aircraft design module configuration list of aircraft No. 10101 of the MA800 aircraft with the top cover configured is as Figure 5 shown.

[0050] A production request for the top cover of aircraft No. 10101 is issued. The information system, based on the information of aircraft No. 10101, Figure 5 the information of the aircraft design module configuration list of aircraft No. 10101 of the MA800 aircraft with the top cover configured as shown, and the information association logic calculation of the assembly instruction process design library information that has been formed, matches the effective assembly instructions and their assembly instruction string parallel relationship information, and forms the production execution assembly instruction file database data for the top cover of aircraft No. 10101: namely, AO_MA800-5410-31110-001-981-100, AO_MA800-5410-3100-001-981-100, AO_MA800-5410-3100-001-981-200, AO_MA800-5410-3100-001-982-100, and the MA800 top cover assembly instruction list for production execution.

[0051] This method is applicable to aircraft that implement modular design and can generate aircraft module configuration lists, which can simplify process design management, greatly reduce the frequency of assembly instruction changes due to changes in the effectiveness of the design digital model, and also reduce the operation errors of manually specifying effective assembly instructions.
