In the annals of China's high-speed rail, the name Liang Jianying shines brightly. She, a 34-year-old woman, with amazing perseverance and wisdom, created a miracle that attracted the attention of the worldLet China's high-speed rail realize the gorgeous transformation from "following" to "leading".Create a glorious "national business card".
Her story, like a movie full of passion and blood, is inspiring and moving. Her life trajectory seems to be an inspirational blockbuster, inspiring countless young people to chase their dreams and realize their self-worth.
In this Spring Festival season, when we take a comfortable and fast high-speed rail and feel the rapid changes of the motherlandWe must not forget those who have paid silently, and it is they who have created the glory of China's high-speed rail with their wisdom and sweat.
She is a girl born in Shandong, and her childhood memories are filled with the roar of trains. Her father worked at the train station, so from a young age she had the opportunity to observe these massive steel behemoths up close.
For her, the train is not only a means of transportation, but also the starting point of her childhood dream. She often fantasizes about the day when she can study these high-speed machines and unravel their mysteries.
The whizzing train never stopped for her to take a closer look, so she studied the railroad. In her free time, she strolls along the tracks, scrutinizing the tracks, sleepers, and trains, each part of which fascinates her.
She was always curious, why couldn't the train go faster? In this way, the railroad became her closest companion in childhood and adolescence.
In 1992, she was successfully admitted to Shanghai Railway UniversityFulfilled her dream. On the day of the opening of the school, the more than 50-hour train journey from her hometown to Shanghai made her feel tired and uncomfortable.
The crowded carriages and bumpy distances made her deeply appreciate the inconvenience of train travel. Later,During an overseas trip, she suffered from motion sickness, and this experience made her determined to develop a faster and more comfortable train.
In 1994, her friend invited her to visit Switzerland, hoping that she would be able to experience the country's natural beauty. But the trip was a big disappointment for her.
She took the famous "Glacier Express", but this so-called "fast train" was surprisingly slow, and the 291-kilometer journey took eight hours to complete.
The old train and complicated road conditions made Liang Jianying endure the pain of bumps and dizziness throughout the whole process, and the beautiful scenery became boring.
This experience once again made her determined to make a train that was fast and not dizzy.
She understands that real progress comes from deep thinking and bold innovation on existing problems. She firmly believes that through her own efforts, she will be able to create a better means of transportation, so that more people can enjoy a comfortable and fast travel experience.
She is an engineer full of passion and dreams, and has been determined to contribute to the railway industry in China since she was a child.
After unremitting efforts, she successfully graduated from university and joined CRRC Qingdao Sifang Locomotive and Rolling Stock Co., Ltd. to start her career.In grassroots work, she started as an ordinary technician, and although the work was tedious, she never slacked off. She has an in-depth understanding of the composition, operating principle and operation process of the vehicle, and has won the respect of her colleagues and the recognition of her leadership with her diligence and wisdom.
In 2004,She was appointed as the chief designer of the EMU R&D and design projectIt was tasked with increasing the speed of the train to an unprecedented level.
At that time, the traffic situation of China's railways was relatively backward, which was undoubtedly a huge challenge for Liang Jianying and her team.
In order to achieve this goal, she led the team to introduce a 200 km/h bullet train in order to expand the idea. However, the foreign engineers in charge of this matter at that time had an arrogant attitude, unwilling to share core technologies, and unwilling to carry out in-depth research and innovation.
It is said that on one occasion, Liang Jianying asked a foreign engineer for advice on how to reduce bumps and make passengers more comfortable when the bullet train was driving at full speed of 350 km/h, but was met with ridicule and angry responses from the other party.
This incident made her deeply realize that the core technology cannot be bought, and only by relying on her own efforts can she achieve true independent research and development.
She began to encourage her team members to have the confidence that success can only be achieved through continuous trial and improvement.
In the days that followed, she led the team to work around the clock, experimenting with new materials and design solutions.
Finally,In just one year, they have successfully developed a domestic EMU with a speed of 300-350km per hourLeave those who once despised them speechless.
On August 1, 2008, the Beijing-Tianjin intercity railway with a speed of 350 kilometers per hour was officially opened, and China's high-speed rail brand "Harmony" was an instant hit.
Liang Jianying's team once again rose to the challenge and started a new goal of comprehensive independent innovation - to design the CRH380A high-speed EMU of the "Harmony" series, the world's highest-speed EMU.In this process, Liang Jianying and her team have put in a lot of hard work. They traveled all over the country and conducted a lot of experiments and research.
Sometimes, a seemingly ordinary number needs to be repeated hundreds or even thousands of times under hundreds or thousands of experiments.
After two years of hard work, the CRH380A high-speed EMU was finally successfully launched in 2010, and the results after trial operation are equally amazing!
The speed of the CRH380A broke through 486The speed of 1 km/h was the highest speed in the world's railway operation test at that time!
She has grown from an ordinary high-speed rail newcomer to a tech-savvy high-speed rail goddess, and her success stems from her persistent pursuit of dreams and deep understanding of technology.
Her story inspires us to work hard to achieve our dreams. She is our role model and allows us to work hard to achieve our dreams.
Long before the "Fuxing", Liang Jianying was already the leader of the "Harmony" EMU. The successful launch of this EMU marks a major breakthrough in China's high-speed rail technology, which not only improves the efficiency of domestic transportation, but also wins wide attention in the global market.
But Liang Jianying and her team were not satisfied with this, they knew that the pace of technological progress would never stop, so they began to develop itA new generation of "Fuxing" EMUs.
The development of Fuxing was challenging, and Liang Jianying and her team had to face a series of technical challenges. Their first focus was on the design of the body, in order to reduce drag and improve energy efficiencyThey carried out a lot of calculations and simulations, and even piled up a mountain of design drawings.
Although the existing CRH380A EMU has reached the international leading level, Liang Jianying is still not satisfied.
They are also working to reduce the noise level of the trainsShe demanded even more – a further 3 decibels lower.
This seemingly small improvement actually represents a huge technical challenge, and she and her team have been working hard for more than a yearMore than 3,000 tests were carried out, and the goal was finally achieved.
These technical difficulties have been successfully overcomeWhen the "Fuxing" EMU was put into operation in 2017It has won wide acclaim for its excellent performance and comfort.
It is in a leading position in the world in terms of operation speed, safety, energy saving and consumption reduction, which not only enhances China's international status, but also sets a new benchmark for global rail transit.
While the speed is soaring, she also incorporated many design elements rich in national characteristics when designing the "Fuxing".For example, the EMU is named "Flying Dragon", which symbolizes the great rejuvenation of the Chinese nation and the take-off of the Chinese dragon.
These ingenious design concepts not only endow the "Fuxing" with rich cultural connotations, but also make it a beautiful cultural business card, showing China's innovative strength and cultural confidence to the world.
Although great achievements have been made in the development of China's high-speed rail, the challenges in the future are still huge. In this process, we need to continue to adhere to scientific and technological innovation, constantly improve the technical level, and pay attention to talent training, so as to lay a solid foundation for achieving more brilliant goals.
In this era of rapid development, are there other modes of transportation that can replace or complement high-speed rail? In any case, we all believe that as long as we work hard and keep forging ahead, more miracles will happen in China's future. Let's look forward to that day together!
