As the saying goes, the family has a family law and there are rules. In the early stage, China experienced many quality problems in the food industry, endangering the lives of ordinary people. This is because the relevant quality inspection standards of the food industry and the laws and regulations on penalties are not perfect. With the development of CAE technology in all walks of life and application in China, how to ensure the standardization and standardization of CAE technology application will gradually mention the agenda. After all, nowadays, in the CAE industry, due to the lack of relevant standards and norms, its rapid development also has serious hidden diseases, which are mainly manifested in:
1. CAE software is available in a variety of ways, and its performance is even worse. Especially in recent years, with the rapid development of domestic manufacturing industry, more and more businesses are eager to develop the CAE market in China, and strive to develop relevant CAE software to better meet the needs of the domestic market, and even some private enterprises. Join the team of CAE technology research and development. This is undoubtedly quite beneficial for the development of CAE technology in China. But who is responsible for the authoritative assessment of CAE software that is developed and will be placed on the market? According to what kind of criteria to judge the pros and cons of CAE software? Including the foreign import CAE software that is constantly influx at the same time, are all their technologies reliable and reliable? Is it not necessary for some CAE software vendors to update one year and one version without substantial technical improvements? If these problems are not solved by the relevant departments, most enterprises will not be able to avoid the blind introduction phenomenon in the application of CAE technology, so that they can use their own products to do the experimental field of CAE software, and ultimately lose the interests of the application enterprise and the whole country.
2. Lack of training and qualifications for CAE technical personnel. The blogger has repeatedly discussed and analyzed the qualities that CAE practitioners must possess. However, who will determine the necessary qualifications for CAE practitioners? Apply the same software to analyze the same problem. Different CAE analysts sometimes get different results. Which one is correct? This is indeed a good job in the domestic construction industry, because all registered structural engineers or supervising engineers and other practitioners need to undergo a rigorous qualification examination to standardize and guide practitioners to master relevant technical and normative knowledge. It is not that all CAE practitioners must undergo a rigorous examination as a registered structural engineer to obtain qualifications. At the very least, they must develop relevant industry operating technical specifications to guide them in proper operation and analysis. Otherwise, taking the wrong analysis results to guide engineering practice will pay the price of blood. This is by no means an alarmist.
3. Lack of technical guidance for the correct and rational application of CAE technology in different industries. How to choose the relevant CAE software suitable for the industry or which software is relatively authoritative in this industry? We can't just look at the propaganda of software developers, because in their eyes it seems that there is no problem that software can't solve. What problems should you pay attention to or avoid during the application software analysis of specific problems? Especially in the industry, some common problems, such as the simulation of the pin shaft in the heavy machinery industry, the simulation of the wire rope or the tie rod, etc., how can we deal with the project reality to the maximum extent? Even for specific industry-specific components, the selection of unit types in the process of finite element analysis, the division of unit size, the method of force application, and the definition of constraints can be used to define and guide qualitative and even quantitative. To accomplish such a task, it is necessary to develop relevant CAE industry standards to guide and implement the standardization and standardization of CAE technology applications, thereby effectively avoiding diversification or misrepresentation of results in the application of CAE technology.
In short, with the popularity and development of CAE technology, it is also urgent to develop CAE industry standards. It is undeniable that due to the diversification and complexity of CAE technology applications, it is difficult or even impossible to develop CAE technology application standard specifications applicable to all industries. However, if dispersed, according to different industry characteristics, the development of specific industry CAE standards, such as heavy machinery manufacturing industry, automotive industry, construction industry, etc., should be easier to operate, it will be more targeted. Moreover, these industries generally have relevant standard specifications, and the CAE technical standards are incorporated into a certain specification (such as the steel structure design specification of the heavy machine manufacturing industry and the construction industry) as part of it. It will be more reasonable and effective.
