Chapter 329 Automatic Track Laying Machine and Shield Machine 2

As Li Yang finished speaking, the entire headquarters was in an uproar. The engineers quickly split into two groups and began to work intensively.

Li Yang first came to the team responsible for the automatic track laying machine model. He took out a small notebook from his pocket, quickly turned to one of the pages, and began to explain the core technology of the automatic track laying machine to the engineers.

"The key to the automatic track laying machine lies in its precise control system," Li Yang explained as he drew a picture. "We need to install a miniature laser distance measurement system and positioning module on the model. These two systems work together to ensure the accuracy of track laying."

The engineers took notes carefully and nodded to show their understanding. Li Yang continued: "The mechanical part of the track laying machine is also critical. We need to make a robotic arm that can automatically grab, place and fix the track. This robotic arm needs to have at least three degrees of freedom to simulate the movements of a real track laying machine."

A young engineer raised his hand and asked, "Mr. Li, how should the control system of this robotic arm be designed?"

Li Yang smiled and replied: "Good question. We can use stepper motors to control each joint of the robotic arm. Then, we need to write a simple control program to enable the robotic arm to move along the preset trajectory."

He picked up the chalk and quickly drew the block diagram of the control system on the blackboard. The engineers looked at the complex lines and symbols with admiration and respect in their eyes.

"Remember," Li Yang stressed, "although this is just a demonstration model, we must restore the working principle of the real track laying machine as much as possible. This is not only to give a good impression to the leaders, but also for us to better understand this technology."

The engineers nodded one after another, their faces full of determination and confidence. They immediately began to divide the work and cooperate with each other, some were responsible for the design and production of mechanical structures, some were responsible for the development of electronic control systems, and some were responsible for the overall assembly and debugging.

Li Yang looked at their busy figures with satisfaction, and then turned to the group responsible for the shield machine simulation system. The work of this group was more complicated because they needed to develop a computer simulation system that could demonstrate the working principle of the shield machine in a short period of time.

"The core of the shield machine is its cutterhead system," Li Yang explained to the computer screen. "We need to simulate the stress and cutting effect of the cutterhead under different geological conditions. This requires the use of complex mechanical models and numerical calculation methods."

He typed quickly on the keyboard, and lines of code appeared on the screen like flowing water. The engineers stared at the screen intently, trying to keep up with Li Yang's thoughts.

"Look, here we use the finite element method to simulate the stress distribution of the cutterhead," Li Yang said, pointing to a piece of code on the screen. "Then we need to build a dynamic geological model that can reflect in real time the various stratum changes encountered by the shield machine during advancement."

An experienced engineer said thoughtfully: "Mr. Li, your model is very thoughtful. It can not only be used for demonstration, but also be of great use in actual construction in the future."

Li Yang nodded approvingly: "Yes, that's our goal. We not only want to demonstrate the technology, but also lay the foundation for future practical applications."

He went on to explain: "In addition to the cutterhead system, we also need to simulate the shield machine's propulsion system, slag removal system and segment assembly system. The coordination between these systems is the key to the efficient operation of the shield machine."

The engineers listened attentively and offered their own ideas and suggestions. Li Yang patiently answered every question and constantly improved the design of the simulation system.

As time went by, the work of both groups made significant progress: the model of the automatic track laying machine had taken shape, and the simulation system of the shield machine was able to demonstrate the basic workflow.

In the early hours of the morning, Li Yang came to the model of the automatic track laying machine, carefully checking every detail and making suggestions for revisions from time to time.

"The movements of the robot arm are not smooth enough," he pointed out. "We need to adjust the control parameters of the stepper motor. In addition, the track fixture needs to be improved to ensure that each section of track can be accurately connected."

The engineers immediately started to make changes. Li Yang then turned to the shield machine simulation system team and carefully checked the data and images on the screen.

"The accuracy of the geological model needs to be improved," he said. "We need to be able to simulate more complex geological conditions, such as faults and caves. In addition, the simulation of the slag discharge system needs to be more realistic, taking into account the impact of different water contents on slag discharge efficiency."

The engineers carefully recorded every suggestion of Li Yang, and then worked non-stop to modify and improve them.

The headquarters was brightly lit throughout the night, filled with a tense and enthusiastic atmosphere. Everyone was working hard to complete this seemingly impossible task in just a few hours.

Finally, at dawn, both projects achieved breakthroughs: the automatic track-laying machine model was able to smoothly complete the track-laying action, and the shield machine simulation system was able to vividly display the entire tunnel excavation process.

Li Yang looked at the results in front of him with a gratified smile on his face. He knew that these were not just two models or systems, but the crystallization of the wisdom and efforts of the entire team.

"Comrades," Li Yang said loudly, "you have done a great job! This is the wisdom and strength of our Yan people. I believe that with these two demonstrations, we will be able to let the leaders see our determination and ability!"

Although the engineers were exhausted, their faces were filled with pride and excitement, for they knew that they were involved in a great project that could change the face of the country.

At this moment, the sound of a car engine came from a distance. Li Yang looked at his watch, took a deep breath and said, "It's time, the leaders are here. Let's go and greet them together and show the wisdom and strength of our Yan country engineers!"

As Li Yang finished speaking, everyone straightened their appearance and walked out of the headquarters with their heads held high. Their eyes were shining with confidence, because they knew that they were participating in a great cause that would change the fate of the country.

In the sunshine, Li Yang led the team to stand at the entrance of the construction site, welcoming the slowly approaching black car. The car door opened, and several leaders in Mao suits got out. Li Yang stepped forward and warmly welcomed them: "Welcome all leaders to come and give us guidance!"

The leaders nodded amiably, and one of the white-haired elders said, "Comrade Li, we heard that you have made a new breakthrough, so we came here specially to take a look."

Li Yang smiled and replied: "Yes, thank you for your concern. We have indeed made some new progress. Please follow me. We have prepared a detailed report for you."

He led the leaders into the temporary exhibition hall. The first thing that caught their eyes was the model of the automatic track laying machine.

"This is our latest developed automatic track laying machine," Li Yang proudly introduced, "It can greatly improve our track laying efficiency and ensure the accuracy of the track."

He pressed the switch and the model started to work. A small robotic arm flexibly grabbed a section of micro track, placed it precisely at the predetermined position, and then quickly fixed it. The whole process was smooth and breathtaking.

The leaders opened their eyes wide, with expressions of surprise and admiration on their faces.

"It's amazing!" a leader exclaimed, "With such efficiency, wouldn't our speed in laying high-speed rail be several times faster?"

Li Yang nodded, "That's right. Moreover, this automated track laying is not only fast, but also very accurate. It can ensure that each section of track is perfectly connected, providing the smoothest driving experience for our high-speed trains."

Then, Li Yang led everyone to the shield machine simulation system. A three-dimensional tunnel excavation model was displayed on the big screen, vividly showing the entire process of the shield machine's operation.

"This is the tunnel boring machine simulation system we developed," Li Yang explained. "Through this system, we can simulate the tunnel excavation process under various complex geological conditions, greatly improving our construction efficiency and safety."

He operated the keyboard and called up different geological models. On the screen, the shield machine traveled through various complex geology, clearly showing how it coped with various geological problems such as faults and karst caves.

The leaders watched intently and nodded their heads in approval. The white-haired old man said excitedly: "Comrade Li, your technology is amazing! With this, we can build high-speed railways to every corner of the country, and we don't have to worry about the high mountains and long roads anymore!"

Li Yang said modestly: "This is the result of our team's hard work day and night. Our goal is to build the world's most advanced, safest and most efficient high-speed rail network, so that our country can truly achieve 'high-speed connectivity and turn natural barriers into thoroughfares'!"

The leaders smiled with satisfaction. The white-haired old man patted Li Yang on the shoulder and said earnestly: "Well done, Comrade Li. Your spirit of innovation and breakthrough is exactly what our country needs. On behalf of the country, I would like to express my heartfelt thanks and respect to you!"

Other leaders also expressed their agreement, praising Li Yang and his team for their significant contributions to the country.

After the visit, the leaders expressed their support for the project again before leaving. The white-haired old man said solemnly: "Comrade Li, you can do it boldly. The country will fully support your work. I believe that with your efforts, we will definitely build a world-class high-speed rail network!"

After watching the leaders leave, Li Yang turned to face his team, his face filled with the joy of victory. "Comrades," he said loudly, "we succeeded! The leaders highly praised and fully supported our work. This is not only an affirmation of our past efforts, but also an encouragement for our future work. Let us continue to work hard and strive to realize our high-speed rail dream!"

The engineers burst into warm applause and cheers. Everyone's face was filled with smiles of pride and excitement. They knew that they were participating in a great project that would change the face of the country, and this was just the beginning.

With the departure of the leader, the entire construction site returned to its former busy state.
