Character experience
Wu Bin was born in Hangzhou on March 8, 1965. A handsome young man. Wu Bin has been working as a bus driver in Hangzhou Changyun Passenger Transport Company No.2 since 2003. On May 29, 2012, he drove the bus as usual. When the bus was driving on the Shanghai Yichang expressway, a rectangular brake pad hit him in the abdomen and arm. He held back the pain and stopped the bus. He pulled the handbrake and flashed the double yellow light. He bought 24 passengers' safety with his own life.
Accident details
unexpected trouble
At 7:10 a.m. on May 29, 2012, Wu Bin drove Zhejiang a19115 bus from Hangzhou to Wuxi, and arrived at 10:10 a.m. smoothly. After an hour's rest, at 11:10, he set out again from Wuxi station, ready to return to Hangzhou. He worked for nine years without any accidents. But this time, he didn't return safely.
At about 11:40, when the vehicle was driving to the Yangshan section in the direction of Yixing on Xiyi Expressway (in Jiangsu Province), a piece of iron (later identified as the brake hub fragment) suddenly flew down from the air, smashed the front windshield of the vehicle, and then hit Wu Bin's abdomen, resulting in liver rupture, multiple rib fractures, lung and intestinal contusion.
Safe parking
At the critical moment, he endured severe pain and slowly stopped the vehicle, pulled on the handbrake and turned on the double flashing light. With the high professionalism of a professional driver, he completed a series of complete safety parking measures. Later, with amazing perseverance, he stood up from the cab and told the passengers to pay attention to safety, then opened the door and evacuated the passengers safely. After finishing all this, exhausted the last trace of strength, he slumped in his seat. Wu Bin, he did not leave the most precious first time for himself to dial 120, but for the 24 passengers on the bus.
Last 40 seconds
The car video provided by Hangzhou Changyun has restored the last-minute thrill.
In the video, Wu Bin, with short hair, wears a sky blue short sleeve uniform, a pair of black lens sunglasses and hands holding the steering wheel.
At 11:39:24, a massive object passed through the windshield and hit Wu Bin in the abdomen. Wu Bin seemed to be bounced by this sudden "blocky object". First, he covered his abdomen with his right hand, struggling to stretch his right leg and step on the brake;
At 11:39:52, Wu Bin unfastened his seat belt;
At 11:39:55, stop and pull the handbrake with your left hand;
At 11:40:05, I really want to stand up and tell passengers to pay attention to safety.
At 13:55 on June 1, 2012, Wuxi traffic police announced on Sina Weibo: "the police said that the bus brake trail is straight. What kind of willpower does a driver with a liver suddenly punctured have to use to do this? Passengers spontaneously went to the hospital to see Lao Wu in the rescue. They knew the seriousness of the matter only after seeing Lao Wu fall quickly. We commemorate Lao Wu and his lofty professional ethics. Only such people can think of everyone's safety at a critical moment. "
Cause of the accident
The most beautiful Hangzhou driver
Chen Yibo, head of the safety section of Hangzhou changyunke No.2 company, said that the bus Wu Bin was driving was Jinhua youth Neoplan, and the windshield material was double laminated glass. "This kind of glass will not fall even if it is smashed with a hammer. It will even become spider web like fragments."
Wuxi highway traffic police are investigating the cause of the accident.
At 9:00 on June 1, 2012, officer Cao of the third traffic police brigade of Wuxi Expressway said in a telephone interview, "that piece of metal is not sure what material it is. It has been sent to Nanjing for testing."
There are four main sources of "deadly iron flakes" from eyewitnesses and netizens. Liu Haitao, an expert in road traffic accident investigation and a policeman of Jiangdu public security traffic patrol brigade in Yangzhou, who was once one of the top ten provincial traffic patrol policemen, analyzed the possibility one by one.
A. Hub fragment theory
(proven)
According to the witness at the scene and Wu Bin's colleague, the "lethal iron sheet" is about 30 cm long, 15 cm wide and 1 cm thick. The front is smooth, and there are obvious brake wear marks on the back. It should be debris flying from the broken brake hub of the opposite vehicle. This view is supported by many netizens. In this regard, Liu Haitao said that because he did not see the iron sheet with his own eyes, he did not dare to conclude that the iron sheet was flying out of the brake hub of the opposite car. However, it is possible that if the brake hub of the opposite vehicle is suddenly damaged while driving, its own speed and direction may completely break the bus glass, causing fatal injury to Wu Bin.
B. The theory of artificial parabola
Some netizens also asked, could it be that the people on the opposite car inadvertently threw out this piece of iron on the way, or that the iron pulled by the truck on the opposite side flew out? Liu Haitao thinks it is impossible. According to the eyewitness's description, this piece of iron is not small and has a certain weight. Although the speed can help, it is still very difficult to cross the isolation belt. Children can't do it, but how can adults do it on the highway?
C. The ground lost theory
Many netizens speculated that the "fatal iron sheet" was accidentally left on the road by a car in the past, and then jumped up and flew over the isolation belt after being crushed by the big car behind? Liu Haitao thinks that this possibility is possible, but it is very little. Because in order to roll such a large piece of iron up and fly, the angle of rolling must be very tricky. The edge of the wheel should quickly brush the edge of the iron, so that the iron can be thrown up, just like the stone flying up and down by the wheel.
D. Rocket debris theory
(it has been confirmed that the statement is not true) yesterday morning, netizen @ Heqing posted on Sina Weibo: on the afternoon of May 29, 2012, some rocket debris fell into Xunyang County, one of which fell into a rice field in shizuanwan village, Shuanghe town. On the same day, Wu Bin of Hangzhou Changyun passenger transport company was seriously injured and died. It happened on the same day. Could it be the wreckage of the rocket. Some netizens retorted that Wu Bin's misfortune was at about 11:40 on May 29, 2012, while the rocket launch was at about 3:00 p.m. on the same day. In addition, the location didn't match. This kind of argument is self defeating. @He Qing apologized later.
technical analysis
It takes only 0.0002 seconds for the flying metal to break through the glass
According to Wu Gang's conjecture, the iron pieces smashed into the bus were probably fragments flying out of the brake drum of the opposite vehicle. In order to find out the cause of the accident, Jin Baizheng, deputy chief engineer of Hangzhou Changyun group, came to associate professor Wang, who majored in mechanical engineering of Zhejiang communications vocational and technical college, and asked her to calculate the instantaneous velocity, impact force and destructive force of the "suspected brake drum debris".
According to the bus speed of 94 km / h and the minimum speed limit of 70 km / h for trucks with brake drum debris falling from opposite lanes, Associate Professor Wang calculated that the instantaneous speed of iron plate was about 164 km / h, that is, 45.6 meters per second, which was one tenth of the speed of pistol bullets.
The thickness of the windshield is 9 mm, and it takes only 0.0002 seconds for the iron sheet to break through the glass. The impact force produced is 4 times more than the standard of the windshield.
According to the momentum theorem, after breaking through the glass, the iron sheet also flew to Wu Bin's abdomen at a speed of 30 m / s, producing an impulse of about 90 ns, which is equivalent to 2.5 kg of iron sheet falling from a height of 50 meters and hitting Wu Bin's abdomen.
Honorary title
On June 2, 2012, in recognition of Wu Bin's advanced deeds and noble spirit, Hangzhou decided to award Wu Bin the title of Hangzhou moral model (civilian hero). Hangzhou Municipal Commission of civilization said in an official document that all localities, departments and the broad masses of cadres and masses in the city should take the construction of the socialist core value system as the foundation, vigorously strengthen the construction of civic morality, extensively carry out learning activities from Comrade Wu Bin, learn from him the sense of responsibility, the spirit of dedication, and the professional ethics of scrupulously performing his duties, and establish correct values to realize the goal The international action will make due contributions to "building a city of Oriental quality and building a happy and harmonious Hangzhou".

At the same time, Hangzhou carried out activities to learn from Comrade Wu Bin.
On the afternoon of June 4, 2012, the Ministry of transport announced that Wu Bin was awarded the honorary title of "model driver who loves his job and is dedicated to his work", and carried out the activity of learning from Wu Bin in the whole industry.
