In the summer, Zhai Wanming, a member of the National Outstanding Communist Party and Academician of the Chinese Academy of Sciences in Southwest Jiaotong University in Chengdu, led several graduate students to measure data in the rail transit laboratory.

Zhai Wanming's research has written a heavy pen in the history of railway science and technology. Based on the classic vehicle dynamics and rail dynamics theory, he created a new theoretical system of "Vehicle -Rail Coupling Dynamics" and was highly evaluated by the academic community.

"In my opinion, the combination of trains and rails is a kind of coupling, and the combination of party members' aspirations and the needs of the times is a more important coupling." Zhai Wanming said.

In 1981, 18 -year -old Zhai Wanming was admitted to Southwest Jiaotong University. He took a train from his hometown in Jiangsu to Sichuan and was the first person in the family to take a train. At that time, the train was slow and crowded. He stood for a day and one night until Guiyang had a seat. This strongly stimulated him because he enrolled in the railway traffic.

Personal pursuit, the mission of the party and the nation, quietly resonated in his heart. By the first semester of studying for a master's degree, he joined the Communist Party of China gloriously.

"Since 1997, my country’ s railway has been accelerated 6 times, and the speed has continued to increase. More and more new methods need to solve a series of technical problems in railway acceleration and high -speed railway key construction projects. "Zhai Wanming said.

He keenly realized that it was important to solve the dynamic problem of the overall system of vehicles and rails. It was very important, and tried to establish a unified track model of vehicles, but it also needed a large number of calculation simulation and test verification.

Due to the limited computing equipment at that time, everyone was rushing to use a computer during the day or even after dinner. After waiting at about 11 pm, after waiting for others to leave, he drilled into the computer room, operated more than a dozen computers, entered the setting conditions of the setting one by one, and in the setting of the setting. A note on each computer's keyboard: "Zhai Wanming is using the machine, please do not move." Tian Yi Liang rushed to the machine room early and collected various data calculated last night.

Numerous star nights are accompanied by youth and coexist with the original intention.

His footprints spread throughout the Beijing -Tianjin intercity railway, Beijing -Shanghai high -speed rail, Chengdu -Chongqing Railway, Daqin heavy -load railway ... Through on -site surveys and repeated experiments, while solving engineering problems, he also obtained a large number of first -hand precious data Essence Computing, simulation, and experiments confirmed each other, enriched and improved his theory, and promoted China's railway technology to gradually overcome high -speed driving vibration problems and move towards the forefront of the world.

"Today's 'vehicle -rail coupling dynamics' has become the basic method of research on rail transit dynamics at home and abroad. This is the epitome of China's railway technology progress." Zhai Wanming said.

In recent years, Zhai Wanming proposed the best matching design principles and methods of motor vehicles and line power performance, presided over the study and establishment of the theory of train -track -bridge power interaction, and developed a dynamic simulation and safety assessment system for high -speed trains. Railway engineering is widely used. He has won the first prize and second prize of national scientific and technological progress, the first prize of the Ministry of Education Natural Science Award, the first prize of the Yangtze River Scholars Achievement Award, the National May 1st Labor Medal, the National Railway Locomment Medal, and the national innovation compete for the first prize. In 2021, on the occasion of the 100 -year party, he was awarded the honorary title of outstanding Communist Party members across the country.

Zhai Wanming attaches great importance to the cultivation of young talents, and has trained high -level talents in rail transit of hundreds of master's, doctoral, and postdoctoral traffic for the country. "my country's high -speed rail mileage is more than 40,000 kilometers, ranking first in the world. How to further tap its potential and give full play to greater value? What is the highest operating speed of a safe economy? The ultimate question of high -speed rail requires our party members to answer."

"Whenever people see the people take the high -speed rail and arrive at high speeds, they will be very pleased. This is a very meaningful thing. The party leads us to rewrite history for the people." Zhai Wanming said.
