Description

System and method for inquiring technical solution of automobile body

Technical Field

The invention relates to a system and a method for inquiring technical solutions of automobile bodies, in particular to inquiring and managing description files, implementation files or evaluation files of the technical solutions in the field of automobile research and development.

Background

An automobile body is a complex system and generally consists of a plurality of parts of three hundred to four hundred, and the design of each part comprises structural design, material selection design, performance design, process design and the like. The general development process of the vehicle body is that a vehicle body department designs the structure and materials of parts, then transmits the part data to a CAE department for performance analysis, transmits the optimized part data to a process department for process manufacturability analysis after the performance verification and optimization are completed, and finally freezes the technical design scheme of each part. In the process of developing the automobile body, it can be clearly seen that the design of the same part relates to different technical departments, different design fields are related to each other, and the development cycle generally lasts for two to three years, so that a great amount of research and development data relating to different technical fields can be generated in the development process of the automobile body.

Research and development data of an automobile body can be divided into two categories, one is part design data, such as CAD data of part design, and for project development, designing part design data meeting technical target requirements is a key point; the other type is knowledge data, the knowledge data refers to technical solutions designed for supporting part CAD and data related to demonstration and verification of the technical solutions, and for a host factory, effective accumulation of knowledge data generated in the research and development process is the key for improving the research and development capacity.

For the forward development of automobile bodies, knowledge data is more important than part design data, the relation between the knowledge data and the part design data is the relation between fish and fish, and more fish can be hit only by learning how to hit the fish.

For the part design data, in an IT system of a host factory, a unique part number is assigned to each part, and the part number has the characteristic of simplicity, so that the IT system can conveniently perform data management on the data. However, as there is no effective file name designation system for knowledge data as part number designation systems, knowledge data cannot enter the IT system for engineers to search, query and manage.

Currently, in automobile research and development, three types of knowledge data are mainly generated: firstly, a large amount of various analysis reports need to be delivered in the project implementation process, such knowledge data are mainly evaluated aiming at the nodes in the project development process, and have little value for guiding the subsequent projects due to wide and redundant related contents; secondly, various design guidelines and analysis guidelines aiming at improving technical capacity are generally used as guidance for new employees to enter the door, and have little value for guidance projects; thirdly, the method comprises the following steps: the technical documents related to the specific technical solutions accumulated in the project development process have direct reference value for the subsequent project development, the technical pertinence is strong, and the problems, the technical solutions, the implementation, the evaluation and the implementation effects are clearly and concisely described, so that the readability is also strong, and the knowledge data targeted by the invention is the technical solutions. The host factory generally attaches more importance to the first two types of data, and even attaches more importance to the third type of data, however, the inheritance, sharing and utilization of technical experience are seriously affected due to the lack of effective technical management on such technical documents.

Technical documents related to technical solutions, such as historical experience summary or paper summary, are typically deep summary of projects after a certain time node of the project is finished, the documents in PPT or PDF format are stored in personal computers of engineers related to the project, people outside projects inside enterprises are difficult to obtain, the document names are generally 'A project PX node technical summary', the contents in the documents relate to a large number of technical solutions and are 'dry goods', problems, technical solutions, various evaluation effects and implementation effects are described in detail, and the technical documents are complete technical closed-loop solutions and have reference values.

Trying out a scenario, two years after the end of project a, assuming that the relevant engineers participating in project a are out of work or have no parameter project B, and the engineers of project B have encountered a completely similar problem that has been successfully solved in project a, the following assumptions can be made:

assuming that the project engineer of the first project and the project engineer of the second project cannot acquire the technical summary file of the project a, the project engineer of the project B can only be used as a completely new technical problem to search for a technical solution like the project engineer of the project a.

On one hand, the B project engineer does not determine that the required answers exist in the files; on the other hand, the cost for searching uncertain answers in the documents needs to be evaluated, and obviously, the more the technical summary documents, the greater the cost for searching, and generally speaking, the engineer in the project B still can be used as a completely new technical problem to search for a technical solution like the engineer in the project a, but is a more economic behavior.

The above two assumptions are not all assumptions, and in real automobile development, it is more realistic to exist. Under the existing knowledge data management, if the problems encountered by the previous project are expected to be avoided in the subsequent project, one problem is unrealistic to make a mistake, and more cases are that the same problem may repeatedly appear in different projects, therefore, if the knowledge data cannot realize data sharing or cannot realize convenient target data searching, the high-quality summary of project engineering technical problems cannot generate beneficial influence on the subsequent project, more of the engineer personal experience is strengthened, and the experience training accumulated in the project or the successful technical solution is likely to follow the departure of the engineer.
