Zhongyuan Automobile Company undertook the task of customizing a 100-ton capacity tanker for the military, and the company obtained the technical authorization of the bogie of the Scania Group Company, and in the future, each bogie produced will also give the Scania Group Company a patent fee of 5% of the sales, but the Zhongyuan Automobile Company can independently develop this technology patent.

"In the design process, we carried out repeated simulation analysis and structural optimization for each load-bearing component, and carried out 10 million cyclic loading fatigue experiments on wheels, axles, frames and other components to ensure the safety of structural strength in the whole life cycle. ”

Gao Yongjun said: "In the process of making the bogie, we use various measures to reduce weight. The frame of the bogie is welded with a thin-walled box-type structure, and the thinnest steel plate is only 6 mm. In order to reduce the weight control, our technical team worked with Scania Group engineers to develop a detailed weight concept, which can be as small as the weight of a bolt. ”

He also talked about one of the things in the research and development process -

In the development of the 120 kg axle box, the weight of the axle box exceeded the intended weight by 2.5 kg, for this, the technical staff carried out four times of "optimization and then simulation calculation, and then optimization" of the design scheme, and finally made the axle box meet the weight requirements at the beginning of the design.

Peng Huqi carefully inspected the finished bogie at this time, and created a lot of places with no welding traces intact, and the whole product was integrated, and he couldn't help but be amazed.

"In the production of structural structure, welded structure and other components, it is necessary to carry out extremely strict detail control, each weld has a specific skill request, the critical weld should be finely polished, and the welds of these components are senior technicians. ”

Gao Yongjun pointed to the positioning arm of the bogie and said: "This part requires extremely high precision, and it is a component that needs to be ground by hand. ”

Han Shaoqi nodded and said: "I am clear about this, the positioning arm is the contact part between the frame and the wheel on the bogie, and it is connected with the wheelset through the positioning node. At high speeds, the contact surface of the positioning arm is subjected to very heavy impact forces. Our CSR group company has been stuck on this before, how did you do it?"

Gao Yongjun and the others looked at Yang Jie at this time.

Yang Jie smiled: "This is our company's trade secret, so we can't reveal it." ”

Han Shaoqi exchanged glances with Zhang Shuguang, and he also looked regretful.

After the positioning arm is roughed by the machine, there is very little space left for manual grinding, grinding less, the fit rate does not meet the requirements, grinding more, the parts of more than 100,000 yuan may be scrapped, and the process standards are extremely strict, and this is also the core secret of foreign companies such as Scania, which their engineers will not reveal.

In order to overcome the technical difficulties of mass production, Huaxing Group Company also convened the senior technicians of the Machine Tool Research Institute and Chenguang Machinery Factory to think of measures, and finally concluded that the 75% fit rate is the best state.

After this conclusion, it is also concluded that the specific data left for manual grinding is only about 0.05 mm, which is thinner than a hair.

In the end, Ning Yuncong, a senior fitter in his fifties at Chenguang Machinery Factory, came up with a batch processing measure.

After a long fatigue test after the bogie was trial-produced, the experimental data completely confirmed that Zhongyuan Automobile Company completely controlled the core skills of the bogie.

Gao Yongjun saw the expressions of Director Zhang and CSR Han Dong, and also remembered the shocked expressions of these Swedish engineers of Scania Group Company at that time when they learned that they had conquered the positioning arm processing technology.

For this critical processing technology, Huaxing Group Company really took the effort of the old nose, and it was impossible for CSR Group Company to ask the leaders of the Ministry of Railways to ask for skills and the company to take it out for free.

On the morning of Vietnam, Yang Jie received a call from Vice Premier Song Xinyang.

"I heard Zhang Shuguang say that your Huaxing Group Company wants to take over the 'Huaxia Star' high-speed train project?" Song Xinyang asked.

Yang Jie nodded yes.

"Zhang Shuguang: They are very shocked by the technical strength of your company, saying that you control 5 of the 9 key skills required by high-speed trains, which is very remarkable, since you want to undertake this project, I also approve it. ”

"Thank you Vice Premier Song for your support!" Yang Jie said excitedly.

"I hope that you Huaxing can cooperate with CSR Group and CNR Group Company to do a good job in the 'Huaxia Star' project, which can truly make our country have independent intellectual property rights of high-speed trains. Song Xinyang said sonorously on the phone.

Yang Jie also agreed.

In the evening, Yang Jie rushed to Tanya's villa, and when he got out of the car, he also took out a bouquet of flowers and gift bags from the trunk.

When he walked in, many people in the living room looked over.

Today is Tanya's birthday, Zhang Yujie, Qin Rui and others rushed over, and even Xiao Yuhan rushed over.

Seeing him walk in, a light flashed in her beautiful eyes.

At this time, the living room of the villa was also carefully arranged, and it was very birthday-like.

"Everyone is here?" said Yang Jie with a smile.

"I didn't think you were coming. Qin Rui said with a narrow face.

"I don't want to be beaten. Yang Jie glanced at Tanya, who was standing there, and said with a smile, at this time she was already able to walk slowly.

Seeing Yang Jie entering, he teased himself, Tanya glared at him coquettishly: "If you talk nonsense again, I will really do it." ”

Tanya's father went abroad for the assessment, Tanya's birthday did not come this time, Tanya's stepmother Zheng Qiuyue and aunt Tan Qiju came over.

The two of them saw Yang Jie coming, with a smile on their faces, especially Tan Qiju looked at him curiously, she also knew the matter between Tanya and Yang Jie, and said that her niece was really a big disaster, and there would be a blessing if she didn't die, Yang Jie has been helping her in the past few years, and now her net worth is more than one billion, it is said that Wonderful Network will be preparing to go public in the United States in a few years, and her niece's net worth will have to grow to tens of billions, and her net worth will not be worse than her father.

She also made it clear that her eldest brother had a default attitude towards the matter between Tanya and Yang Jie, and of course she was looking forward to seeing Tanya live happily.

To say that she still has a little regret in her heart, Yang Jie in front of her looks like she can't give Tanya a name.

Seeing Tan Ya accept the flowers in Yang Jie's hand with a happy smile, and then took out a delicate box from the gift bag, Tan Qiju and the others also looked at this box curiously, all curious about what birthday gift Yang Jie would give Tanya.

"Wow!"

When everyone saw Tanya take out a mobile phone with a hexagonal angular design from the box, the mobile phone frame is made of titanium, and the titanium frame is hand-polished with 14 facades and 3 different surface effects, which strengthens the visual edges and corners.

The front completely cancels the physical buttons, the screen application is carefully cut and polished tempered glass, the back is made of calfskin material, the company is also the world's largest luxury leather supplier eccoleather cooperation, from more than 100 kinds of leather selected very rare Dutch ranch half-year-old calf head leather, all have uniform lines and flawless, the feel is extremely delicate and soft, the back also has a high-end watch back through the movement, the dial backing and side texture design using plum blossoms and auspicious clouds pattern, full of strong Chinese classical style。
