Chapter 849

It can be said that Tengfei group, which was stuck by Dassault, is unfortunate, but from another point of view, Tengfei group, which is brave and determined to make up for its shortcomings, is also lucky.

Because in the 1980s and 1990s, there were quite a number of technical experts and scientific research institutions devoted to the development of industrial design software.

Even in 1992, the market share of domestic industrial design software was still more than 25%, and the foundation was quite good, which was much better than the embarrassing moment when some engineering university graduates could not find a place in Chengdu even after being dominated by foreign software decades later.

However, this is not the most fortunate thing for Tengfei group. The most important thing is that the domestic price of these industrial software technology achievements at that time was cheap.

On the one hand, it is caused by the competition of the same kind of software abroad. But the most important thing is that the mainstream in China pays more attention to hardware than software. There is no way to do this. Hardware is real, visible and touchable, and it is easy to make achievements. Software is too vague to say, and the technical threshold is still high. Even if it is broken, the leader said, "what can this do?" Instant power breaking.

Therefore, domestic industrial software is not only marginalized seriously, but also suppressed by foreign similar products, resulting in the serious undervaluation of the value of such products.

Apart from other things, in September 1988, with hajif finite element analysis software, all databases, source codes, core algorithms and three full-time development engineers, Tengfei Group paid a total of 480000 yuan.

You should know that the finite element analysis software is the basic modeling software for all industrial design. French Dassault's CATIA software is famous all over the world, but its foundation is also built from the finite element analysis software.

Because of this, if Tengfei group wants to build its own industrial design software system, finite element analysis software is essential.

Therefore, this kind of professional modeling and analysis software can usually sell at a sky high price in foreign countries. One or two million US dollars is the starting price. If you can get by a little, it will cost tens of millions of US dollars. Therefore, the developers have not yet taken out all the core technologies such as source code and database.

But in China, all the cores were taken out, and even three engineers in charge of development and maintenance were crammed in. The result was only 480000 yuan.

Is this hajif finite element analysis software bad?

Of course not. You should know that the finite element analysis software developed by aviation 6xx Research Institute is the top scientific research achievement that won the first prize of national science and Technology Award in 1985.

Even compared with the first-class finite element analysis software in Europe and the United States, hajif finite element analysis software is no worse in basic algorithm, coverage, modeling application and reaction speed. The only disadvantage is that human-computer interaction is not as beautiful and fancy as that in Europe and the United States, and the user experience is slightly worse, but it does not affect the normal application of this kind of software.

There is also the underlying management structure of the entire industrial design software. Tengfei group is a group of language logic, core algorithms purchased from the Computer Research Institute of the Academy of Sciences, as well as a group of engineers who voluntarily follow. This time, Tengfei group has almost no cost and only provides its Lenovo company with a loan guarantee of 300000 yuan.

Let's not say that 300000 RMB is just a trifle for Tengfei group, let's say the loan itself. As a major shareholder of China Merchants Bank, hundreds of thousands of things are just a matter of words for Tengfei group. There is no cost at all.

But it's amazing.

The root of this problem is the MRP Ⅱ software developed by IBM, which was introduced into China in 1976 by the Computer Research Institute of the Chinese Academy of Sciences. After nearly ten years of research, the architecture, logic language and core algorithm of the software have been cracked, and the cacmrp Ⅱ industrial management software has been developed on the basis of it.

With a little change, Tengfei group will launch cacmrp III software suitable for aviation and aerospace enterprises, which includes design, procurement, cost and scheduling, and becomes the core bottom management software of Tengfei group.

In addition to hajif and cacmrp III, Tengfei group has also excavated a large number of industrial software core codes, algorithms and technical personnel from other scientific research institutions and colleges, making Tengfei group have a strong R & D foundation at the beginning.

However, these are not enough. Industrial design software, especially the industrial design software that can be used in all-round production of aviation and aerospace, can not only have the underlying algorithm and architecture. The most important thing is to have rich theoretical data, experimental data and production experience as support.

Tengfei group is strong in this aspect. Over the years, whether it is wind tunnel test, UAV verification test and joint research with relevant colleges and universities, its achievements have been numerous.

As for the first-line production, not to mention, before the development of industrial design software, Tengfei group has cooperated with the Institute of Aeronautical computer to develop industrial control software, which has been successfully applied to the aerospace special equipment developed by Tengfei group. After several years of practice and polishing, it has become one of the few mature and reliable aerospace equipment in China and even in the world Professional industrial control production system.

Therefore, the production data of Tengfei group can be directly imported into the database of design software with a little processing, which has become a crucial reference index in the aerospace design of Tengfei group, so that designers can know the situation of front-line equipment and the real processing conditions without leaving home, so as to avoid the low production efficiency caused by the disconnection between design and production.Of course, this is only a part of the huge industrial design system of Tengfei group. What Zhuang Jianye ultimately wants is not the simple design and limited production docking single software of French CATIA software, but a total factor production system integrating design, tooling, process, procurement, rush, scheduling and production.

When Dassault of France used CATIA software to crush people, Tengfei group used another subversive innovation to blow it to pieces.

"On the basis of the original underlying industrial control software, we added 648 different types of professional analysis software to form a complete set of industrial design software package, forming the jsnb-ii aviation and aerospace comprehensive analysis system we see now."

Peng Chuan simply narrates the development process of industrial design software of Tengfei group. Of course, some sensitive topics have been deliberately erased, just highlighting how difficult and difficult Tengfei group has been in this field in recent years.

Finally, through continuous investment and arduous efforts, we finally built the jsnb-ii aviation and aerospace comprehensive analysis system. People around us were very sorry, but before everyone could recover from the development process of Tengfei group's industrial design software, Peng Chuan's next speech surprised everyone in the audience once again:

"Since the jsnb-ii aviation and aerospace comprehensive analysis system was put into use, we have reduced 94% of the cost and 98% of the design changes compared with the past in the development of trj-500 series aircraft. The precision of various parts and tooling has been increased by 10 times. Therefore, 78% of the tooling cost has been reduced. Therefore, our comprehensive efficiency has been increased by 66.7% It will bring direct benefits of 1.2 billion yuan to the enterprise every year.... "
