C23 There Were Many Difficulties in Finding the Data

While Su Jianguo was studying the train information in his dorm room, his roommate, Xiao Liang, walked in and patted Su Jianguo on the shoulder, making him shiver.

Su Jianguo was so scared that his red and blue pencil fell onto the bed. He raised his head and looked at Xiao Liang in confusion.

Xiao Liang said happily, "Jianguo, I have your number today. Quick, follow me to the security guard. "

"Phone?" Su Jianguo looked at Xiao Liang in disbelief.

"Yeah, it's your phone. " Xiao Liang bumped into Su Jianguo. "But it's not a lady's home. It's a young man. He said that it's called Jianjun Corps. "

"Jianjun!" Su Jianguo was overjoyed as he got off the bed.

"Why are you so happy?" Xiao Liang looked at Su Jianguo, who had run out of his room with a gust of wind.

"Perhaps they are from the same village?" The president, Xiao Fang, walked in.

"Maybe it's true. " Xiao Liang burst into laughter.

Su Jianguo hurriedly ran over to Uncle Liu and asked him a question. Then, he received the phone. At that moment, Cheng Jianjun's excited voice could be heard. "Jianguo, I have a surprising news to share with you. You definitely did not expect it. No, you will definitely be overjoyed. "

"What is the good news?" Su Jianguo was looking forward to the good news of Cheng Jianjun.

For Su Jianguo, being able to obtain the news of Beijing Traffic University's railway technical major was simply more worth celebrating than finding money.

After all, it was the number one academy in China's railway, and it was also the place with the highest achievements in China's railway technology.

"Today, I see our department's professor, Yu Zhanyou! It's that expert who researched the Xin Gan train!" Cheng Jianjun's voice was loud and excited, as if he had picked up a treasure.

"Really? Professor Yu Zhanyou!" Su Jianguo also became happy. "That. . . That. . . Did you hear some of the advanced technologies from the new line?"

"Of course. " Cheng Jianjun happily replied.

"Tell me, quickly tell me, I really want to hear" Su Jianguo's heart was beating very fast. He was currently studying the model of the Xin Gang train. He did not expect that Chengjian Army would be able to communicate with the Xin Gang train as if they were connected by heart.

"There's too much content. . . I can't explain it clearly on the phone. I'm going to have winter vacation soon. I'll tell you in detail when I go back during winter vacation. Right, I'll tell you a few keywords now. Check the computer room in your school and prepare for the lessons first. " Cheng Jianjun instructed.

"Okay, okay. . . " Su Jianguo looked around. He wanted to find pen and paper, but Uncle Liu handed Su Jianguo an old letter and a pen.

Su Jianguo expressed his gratitude to Uncle Liu and said to the phone, "Jianjun, tell me, I found pen and paper. "

"Okay. " The voice of Jianjun Cheng was very loud and he was very excited.

"Professor Yu Zhanyou said that the Xin Gan Line is divided into 0, 100, 200, and the plan was completed in 1992. In 1993, it was officially used as 300. "

"300!" Su Jianguo was astonished.

"Yes, 300 series! At the same time, 400 series is also being planned. " Cheng Jian Jun excitedly said, "Do you know? This time, we are going to conduct a comprehensive speed test. It is very likely that the speed will exceed 300 km / h!"

"Really? It's really amazing. " Joy appeared in Su Jianguo's eyes.

"However, in order to achieve this speed, Professor Yu Zhanyou said that he would need to go through some theoretical verifications. I will now tell you some of the data. " The Jianjun Corps impatiently informed Su Jianguo of the data.

"All right, all right. " Su Jianguo nodded. He placed the phone between his ear and shoulder and started recording the data. "Go ahead. "

"In 1964, the system tested operation, 16 teams, 4 generators with a continuous power of 185kW, Su Guangyu smoked a cigarette for 1184kW, and now it is 220km / h. With the automatic control of the train (ATC), the train will have unlimited equipment. Have you noted it down? " Cheng Jianjun asked.

"I did, I did. What about the 100 series?" Su Jianguo asked expectantly.

"In 1985, with JR Donghai as the center, a large number of tests were conducted on 100 Series. It was an upgraded version of the 0 Series. 16 organizers, 12 foot vehicles, output 1,1040 KW, traction performance increased by 50% compared to the 0 Series, and the maximum angle changed from 22 degrees to 31 degrees. Isn't it very impressive? " Cheng Jianjun asked.

"It's really too difficult. It saves a lot of electricity and increases the kinetic energy by more than half" Su Jianguo was amazed, "What about 200?"

"In 1982, the operation of 200 units was able to resist the ice and snow. It pushed open the 25cm snow on the rail. It has the ability to provide heat. The output of 12 units is 1,1040 kW and can reach 275 km / h. " Cheng Jianjun said loudly, "This is a giant. "

"Wait a minute, let me convert it. According to the 0 Series, 16 teams, if converted to each staffer, 0 Series is 9. 2 KW, and the 200 series is 12. 5 KW. Increase the electrical requirements by 25%. This 200 series must be due to the high demand for electrical output, right? " Su Jianguo was puzzled.

"That's right. The output requirement for the electric motor was 12 RMB per unit, which was about 15km per unit, and it couldn't lower the performance of the motor. " Cheng Jianjun sighed with emotion, "This technology is really amazing. "

"Yeah, how good would it be if we could also have such a technology. " Su Jianguo sighed regretfully.

"However, you still don't know about the modification plan. " Cheng Jianjun revealed the truly exciting part.

"200 Elements still need to be remodeled?" Su Jianguo became excited as well. "Quick, tell me. How do we modify them?"

At this moment, Su Jianguo was clearly captivated by the many new series. He hoped to obtain more information that would allow him to be amazed by this train. It would allow him to grasp the essence of this train and understand the information of the technical core.

"The window of the control room has changed from flat to curved. The entire window is circular. The tri-seat seat can rotate. The train doesn't need to turn around anymore! This design is also helpful in air mechanics. Professor Yu Zhanyou said that this will help the train increase its speed further! " Cheng Jianjun became excited.

"What?! To increase the speed further, is it going to exceed 300 km / h?" Su Jianguo asked in disbelief.

"That's right, exceeding 300 km / h. Is it unbelievable? " Cheng Jianjun said excitedly, "Our department's teacher said that he would send us to meet this big guy's model in a few days. I'll tell you in secret. My teacher is also researching the power train that exceeds 300km / h, hoping to get some inspiration from the new train. "

"If there's any progress in the project, you must tell me. " Su Jianguo became more and more excited.

"No problem. Oh, right. Do you know what the 300 series is like?" The more Cheng Jianjun talked, the happier he became. He even forgot about the phone bill.

Yes, to be able to meet the knowledge that he hoped to obtain in his lifetime, so what if he was short of money overnight? If he heard of the Dao in the morning, he would die in the evening, wouldn't he?

To seek knowledge and ask questions, one needed to be truly knowledgeable and insightful, and even more so, one needed to have a thirst and persistence for knowledge.

"Tell me, quickly tell me, Wang Yao said. I can't wait any longer " Su Jianguo encouraged Jianjun.

"I plan to start the 1992 test run. In 1993, the 300 departments officially started operating, although they are currently in the research and development stage. However, according to foreign literature, The 300 departments plan to introduce all kinds of new technologies, such as VVVF control. Non-shaking pillow to turn around, aluminum alloy car, etc. The most important thing is, The most important thing was that the height of the car was lowered by more than 30 cm, which was the best way to save money. However, what was even more surprising was that the height of the vehicle was reduced by more than 30 cm. Do you know what it is?" Cheng Jianjun impatiently said.

"What is it?" Su Jianguo was waiting for the good news.

"Although the 300 series uses the 16-car arrangement of the 0 series, it uses the technology of communication regenerative brake. This technology uses a whirlpool brake for the tow truck. If calculated at 220km / h speed, the electricity consumption of the 300 series is about 70% of the power consumption of the 0 series, and the energy consumption of the 100 series is 90%!" Cheng Jianjun's words shocked Su Jianguo to the extreme.

"What!? The vortex started moving! Communication Regeneration Brake! Only 70%. My god, how much power do we need to save?" Su Jianguo said in disbelief.

"Not only that, every seat has been expanded by 3 cm, increasing the comfort level, and even reducing the noise level! Isn't that unbelievable? " Cheng Jianjun said proudly.

"Yes, I was simply stunned. " Su Jianguo shook his head. "I'm truly too excited. It's true. I have to record down what you said and go to the microcomputer room to inquire about these technologies. However, there's something I need to ask you. "

" We are good brothers. If you have something to say, just say it. " Cheng Jian Jun promised.

"Foreign literature, my English and Japanese are not good, can you translate. . . "Su Jianguo said in embarrassment.

"No problem. When my teacher is doing this research paper, I will download the document in Mandarin and print it for you. " Cheng Jianjun promised.

"Thank you so much. We'll see you on that winter vacation. " Su Jianguo agreed with Chengjian Army.

"All right. Oh. . . When I get excited, the phone bill is gone. You have to treat me to a meal. . . Pay me the phone bill. " Cheng Jianjun said loudly.

"Okay. I will treat you to a meal. " Su Jianguo promised.

After hanging up the phone, Su Jianguo looked at Uncle Liu in embarrassment. "Uncle Liu, thank you. . . "

"Little Su, you are a good child who works part-time. You usually help me clean up and pass me a pen. No need to thank me. Was it your friend just now? He seemed to be quite enthusiastic. " Uncle Liu smiled.

"Yes, he's my friend. Tell me about the train. " Su Jianguo nodded.

"It's a good thing for young people to study. All the best. " Uncle Liu smiled.

"Okay, I'll work hard. " Su Jianguo waved his hand. "Uncle Liu, I will return to the dormitory first. "

"Mhm. "

Only then did Su Jianguo return to his dormitory. Xiao Liang came over. "Look, he is our study marker after all. After he went out, he wrote down a bunch of data. Let me see what this is. . . Eh? New line!"

" Hey, you don't have to say, it's really a new dry line. . . Alright. . . Little Su, you can still get such a complete set of data? We don't even have this in our textbooks. " Little Liang smiled very brightly.

"Is that so? Let me see. . . It really is the data of the new line. " She Chang Xiao Fang came over, "But it is the first time I have seen some of the data on it, I'm afraid it will be hard to find the information. "

"What, the dorm leader, are you interested in the new thread as well?" Xiao Liang asked curiously.

"This is one of the most outstanding trains at the moment, how can I not be interested? However, Xiao Su, do you mind if we help you look for information and learn this parameter together? " Lil' Fang also hoped to learn some new knowledge.

"Sure, I can't find so much information by myself. If the dorm head doesn't mind, then it's the best. " Su Jianguo nodded in agreement.

"Since that's the case, let's discuss this. What kind of information should we search for?" Alright, Xiao Fang said.

"Alright. "
