C119 Car Design Safety Brake

Su Jianguo continued to talk about his plans, Cheng Jianjun looked at Su Jianguo's side profile, and in a short 15 years, the person who had been at the starting line with him had changed his appearance, and time had changed the person's original appearance, either strengthened or weakened.

15 years ago, Su Jianguo had been so simple-minded. His mind was filled with thoughts of supporting his poor family to continue living. His mind was filled with thoughts of how to read and how to feed his family.

Fifteen years ago, Su Jianguo was so reckless. He did everything without thinking. He did not care about the consequences of doing anything. However, in fifteen years, this boy had transformed into a steady man. He would think carefully about everything he did. He would do everything meticulously.

Fifteen years ago, he, Cheng Jianjun, was admitted to the number one academy in the railway department, Beijing Traffic University. He became a proud son of heaven and became one of the few undergraduate students.

Fifteen years ago, he, Su Jianguo, was only admitted to Hangzhou's railway technical school and became a technical school student. He was a qualified but not an excellent engineer.

In fifteen years, a technical school student won over a university student. In fifteen years, an ordinary young man became a trustworthy backbone.

Time would really change a person, and it would also really change a person.

Through Su Jianguo's words, Cheng Jianjun saw a mature and steady image. He also remembered the appearance he had seen in the past few years when he first arrived at Shanghai's railway station.

There were many disciples of Su Jianguo and Zhao Cheng who had taught them personally. Each of these disciples was upright and not afraid of being slanted. These disciples only wanted to do things well and do things flawlessly without thinking about their own gains and losses.

Here, the students that Su Jianguo taught in the technical school back then were earnestly expanding their abilities and shouldering their own missions. Now, they had become the mainstay of Shanghai's railway department.

At that time, Cheng Jianjun was jealous. He was jealous that Su Jianguo had many people who believed in him, and he was jealous that Su Jianguo earned his respect by relying on his real ability. However, whoever had talent in his designer team was guilty.

Time would really change a person's perception, and it would also really change a person's initial appearance.

However, time was also the best teacher. It could change a person's appearance, mentality, and the original way of thinking. The only thing that would not change was the original intention, the initial intention, and the dream that had been decided at the age of twelve or thirteen.

Yes, no matter how much time changed, the dream wouldn't change, and the initial heart wouldn't change.

It was no wonder that many people said that they would not forget their initial heart.

Cheng Jianjun slightly opened his mouth. He was really too envious of Su Jianguo. With such a group of cute little friends, he could work together with them to revive the railway technology. As for his team, they did not have any partners, only colleagues.

In this life, it was really not easy to have partners in the same industry, shoulder to shoulder, and back to shoulder.

Su Jianguo turned his head to look at the silent Jianjun Cheng. "Jianjun?"

"Mhm?" Chengjian Army came back to his senses.

"What's wrong with you?" Su Jianguo asked curiously.

"No, I was just entranced by what you said. Continue. " Chengjian Jun smiled.

"Yes, I did experiments with my assistant Little Shen in this place. It should be said that we started experimenting since 2002. This is the experimental data. Take a look at this place. " Su Jianguo used the time he spent repairing the train to make a statistic and analysis of the experimental data on the train.

"Based on the data analysis, we have a chance to deal with the sticky problem. Some of our engineers who are proficient in adhesion brake proposed the idea of the anti-slide anti-air rotary device being installed. Look here. . . "Su Jianguo took out another blueprint.

" Is this what you planned to do in 2002? " Cheng Jianjun did not dare to believe that this was actually made by a group of engineers who graduated from technical schools during their free time.

"The result of our collective effort isn't the result of me alone. You have to know, Not only our Shanghai railway bureau, but also the Hangzhou City railway bureau. Ningbo's railway department, Wenzhou's railway department, Jiaxing's railway station, and my teacher. . . Teacher Cui Jin's students and teachers from Hangzhou's railway technical school worked together to achieve this result. " Su Jianguo patted Cheng Jianjun's shoulder and said proudly.

"Although we are not as educated as the designers, we are not college students. But there's also a heart of research, optimization of technology. It's just that our research methods and experimental methods are different from the designers'. However, If we can succeed this time, according to our estimations, He might be able to save a lot of money for the Hidden Sleeve. If he calculated it in ten years. . . It could reduce the normal maintenance costs by one tenth. If it were to be expanded to the entire country. . . Maybe we can save even more money on the maintenance fees. " Su Jianguo smiled.

"Amazing, truly amazing. This is the first time I have seen an engineer doing research. " When Cheng Jianjun noticed Su Jianguo stunned, he immediately explained, "I have no other intentions. I truly admire you. "

"Hey, I'm not overthinking it. However, I am very touched when you say that. Speaking of which, Jianjun, take a look at this experimental design. What else is not suitable? Give it to Axe Zheng. " Su Jianguo's shameless manner of questioning amused Jianjun Cheng.

"You are being too polite. Let me take a look. " Cheng Jianjun read the blueprint seriously.

In the end, Cheng Jianjun was still a soldier. He studied electricity at Beijing Traffic University. The best was that Jianjun Cheng had more say in some electrical design.

"I think that in this place, perhaps we can add a design that can feedback electricity to the power grid and use it to initiate. Look here, this place, I'll give you a formula, calculate it this way. . . "Jianjun Cheng picked up a pen and began to write the formula on the A4 printer paper.

A smile appeared on Su Jianguo's face. If he followed Jianjun Cheng's calculations, it would be twice the result with half the effort.

"Based on this formula, we can deduce the possibility of constant deceleration. If we can create a constant deceleration speed, perhaps this brake will be even more perfect. It will also reduce the replacement frequency and the cost of replacing the components. " Cheng Jianjun put down his pen and looked at Su Jianguo.

"Amazing, truly amazing. After all, he is a graduate of Beijing Traffic University. " Su Jianguo clapped his hands.

"Hai, this is also our mutual achievement, mutual help. " Cheng Jianjun waved his hand with a smile.

"However, the common power for TCMS calculation will be allocated to the traction control unit (PCUS). There is still a need for some experiments, but. . . I like your suggestion. It is necessary to send redundant power to the concept of the local brake computer. This concept is great, great. " Su Jianguo had always been the type of person whose eyes lit up when he saw good things.

"Do you also think it's not bad? This is the direction that our designer team is researching. Why don't we work together? " The more Cheng Jianjun thought about it, the more he felt that working together with the engineers might be more effective than simply doing research with the designers.

"Of course it's good. " Su Jianguo nodded happily.

"However, the brake level is here. I have another idea. " Cheng Jianjun picked up a pen and continued to write while drawing, "This place, the place where we brake at high speed, because the voltage of the traction generator is limited, the generator works in the constant power supply area, right?"

"That's right. " Su Jianguo looked at Chengjian Jun with a puzzled expression. "You want to make a formula prediction?"

"That's right. After all, when the low-speed zone was being turned on, the voltage of the generator would be adjusted. Then the generator will work within a constant range. And this constant distance would allow the regenerative brake to become constant. Of course, the speed of the regenerative brake would also be constant. If that was really the case, Then the regenerative brake of the train would usually work within a certain range of speed. Assuming that all of this is true, then shouldn't we do a level? " Cheng Jianjun raised his head and looked at Su Jianguo.

"Yes. " Su Jianguo started thinking about the possibility mentioned by Cheng Jianjun.

"And the value of a super brake is to give different dividing speeds according to the model, and to produce a corresponding microcomputer based on the dividing speed that leads directly to the control of the electric brake. Then the main power of the train is the electric brake, and the air brake is the main power of the tow truck. According to the respective auxiliary brake methods, the main power of the train is the electric brake, and the air brake is the main power of the tow truck. In addition to the coordination modes between the two control systems, each car is synchronized according to the coordination modes. When the engine group was stopped, the first priority was to use the regenerative brake, and the air brake was to be used as the backup and replenishment for the regenerative brake. If that's the case. . . " Cheng Jianjun continued.

" If that's the case, as long as we calculate the dividing speed and precise data for the control of the computer, we will be able to achieve such a brake lock mode. " Cheng Jianjun quickly drew a picture.

This picture was divided into three layers. The first layer was the driver's brake control handle, the train information control computer was next to it, the second layer was the car brake control unit BCU and the regenerative brake, and the third layer was the air brake. The first layer was the driver's brake control handle, the second layer was the train information control computer, the second layer was the car brake control unit BCU, and the third layer was the air brake.

"If it can really be done, then the connecting lock mechanism between the electric brake and the air brake has been overcome by us?" Su Jianguo's eyes lit up.

"Yes, if we can calculate this data, we will be able to declare a patent for our China!" Cheng Jianjun nodded.

"That's great, that's great! This will reduce a lot of our workload and save a lot of money for the country. What are we waiting for? Let's quickly formulate a work plan. We need the original data for this experiment. The formulas and relevant information we need to formulate a plan. Let everyone split up and act. " Su Jianguo opened his mouth happily.

"All right, let's start producing this plan. " Cheng Jianjun nodded.

"Brother, I have a feeling that we will leave our names in history. " Su Jianguo was extremely happy.

"Perhaps Teacher Zhao Cheng will be proud of you. " Cheng Jianjun smiled.

"You dare to say that Teacher Zhang Hong will not be proud of you as his son-in-law? When the time comes, we must have a good meal. However, before this, there will be a huge war that we must fight. We must work hard and overcome all difficulties. " Su Jianguo looked at Cheng Jianjun and said seriously," Are you confident? "

"Of course. " Cheng Jianjun smiled. "I have a sense of security when I am with you. "

"Me too" Su Jianguo smiled delightfully.
