2005 3 months, Liu Yonghong join 31, joined the Secretary has a special status?? 31 and post-doctoral co-culture of Central South University. After that, he served basis pumping Division Director of the Institute Research Institute and later was named executive vice president. "Trinity is a place where their talent will always have enough to play the stage waiting for you." This phrase, Liu Yonghong often mentioned. Lectra vibration difficulties Liu Yonghong from the end of 2005 in Pump Truck vibration control. In the course of the study, Liu Yonghong conducted several large-scale experiment, the duration of each experiment are more than a half months, and it took nearly six months, more than 500 pages of analysis carries Liu Yonghong wisdom of sweat. Concrete Pump Truck vibration due to the discontinuous transmission, through the large number of studies, Liu Yonghong finally found a truck vibration control law and will eventually pump arm vibration down to the original 30% -40%, respectively. Liu Yonghong this work to get the "2008 Outstanding Postdoctoral Hunan Province", "31 Group Technology Innovation Award" and so on, in the United States, Europe and other areas also reported a number of patents. Breakthrough in the pump area, the post-doctoral R & D team has conducted a study on the front suspension. The experiment and simulation to solve a positive crane Cab Not completely closed, the system noise transmission between the problems facing hanging ultimately reduce the noise from 80 dB and 70 dB, close to the international advanced level. This year, Liu Yonghong also actively involved in promoting R & D system reform. "Hope to promote change by developing modular product design groups, and professional skills to enhance the promotion of R & D personnel." Liu Yonghong said that the ultimate research goal is to achieve changes in product modular design development, promoting research and innovation, training of top international R & D personnel, the development of world-class quality products, and ultimately create the dream of the world's highest quality products. Laboratory hard Experiment, there is always a variety of stumbling block, bear the brunt of experimental environment. "It was the hottest summer experiment, when debugging field temperatures up to 40 degrees." Liu Yonghong debug field in the experiment recalled the scene, said every time into the debug field in less than 10 minutes, the body would be wet with sweat through. In such circumstances, Liu Yonghong and his assistant to do every experiment on the need to adhere to a large one and a half. Hard work worth it. Liu Yonghong frankly, in the experiment, they had to correct a lot of misunderstanding on the vibration control methods, such as the impact of high frequency vibration method, vibration interference method. In the ongoing experimental and theoretical study, Liu Yonghong find the most appropriate method of vibration damping reverse. Two major difficulties during this period?? On customary public awareness so that everyone recognized the change and the experimental results, he defeated one by one, test and promote all successful. Liu Yonghong test equipment also is a big problem. Liu Yonghong said that when the initial experiment with almost no testing equipment, all used indigenous methods. For example, pump truck boom to detect vibration, they made a simple column, in the center column to hang a hammer, according to a hammer back and forth in the middle column, measured vibration range. "It was by that time the human, very humble." Gradually acquired as the experimental equipment, the team has now Liu Yonghong can accelerometer, proximity sensor, pressure sensors and other advanced equipment to measure. "We are also considering a laser instrument to measure vibration mode, X-ray diffraction measurement of welding residual stress." Liu Yonghong confidence in future research and development.
