Character experience
Gao Gao was born in Beijing,1928165438+1October 15, originally from Duchang, Jiangxi.
1946 to 1950, studied in the aviation department of Beiyang university, and worked as a teaching assistant in Tsinghua University after graduation.
1952, working in Beijing institute of aeronautics and astronautics, teaching materials mechanics, plastic mechanics and other courses, serving as the director of materials mechanics laboratory.
In the early 1960s, Gao studied the fatigue properties of materials, and then studied the load spectrum acting on the airframe structure. According to the previous research results, he developed the "full-wave rain flow counting method". After many practical applications, it is proved that this method is convenient to use and has high calculation accuracy, and it has been used ever since. Since then, the research on fatigue fracture reliability has been carried out, and the determination principle of fatigue crack propagation reliability curve and the statistical analysis method of fatigue test have been put forward.
1986, joined the China * * * production party.
He has been enthusiastic about charity in his later years. On June 30th, 2065438+0/KLOC-0, Academician Gao donated his 50,000 yuan to the Beijing Charity Association to help poor disabled children and the elderly in the event of "China party member Giving Love" to celebrate the 90th anniversary of the founding of the Party.
By June 30th, 20 1 1, he had donated more than 700,000 yuan in cash to charity.
2018165438+1October 15, "Never-weary structural fatigue expert" and senior academicians of Chinese Academy of Sciences celebrated their 90th birthday. Donate 900,000 yuan on his birthday to reward and fund outstanding young talents who have contributed to the aerospace field in related majors of domestic universities.

With Gao's encouragement and guidance, Yan Chuliang, a doctoral student at Beihang University, dared to solve new unknowns and followed Gao to "climb the mountain". Gao thinks that the method of determining the minimum sample number of fatigue test is closely related to solving this problem. Using this method for reference, not only the minimum number of take-off and landing of flight sampling is solved, but also the long-debated confidence problem is solved. Thus, the new concept of "median spectrum" came into being.
After more than 20 years' efforts, the "Domestic Large-scale Aircraft Fatigue Load Spectrum Project" led by Gao completed 65.438+0.86 million program statements through the collection and processing of 860 million measured data of load spectrum and the research on the method of compiling load spectrum, which solved many problems one by one, achieved a breakthrough in compiling aircraft load spectrum in China, and established the principle and system of median load spectrum with more than 90% confidence. Therefore, the project entitled "Compilation principle of median load spectrum of large mechanical structures and its engineering application" won the second prize of 200 1 National Science and Technology Progress Award.
Different from the load spectrum compiled by statistical results at home and abroad at present, the median load spectrum really keeps the one-to-one correspondence between load-time history and various state parameters, so it can truly show the whole process of time-dependent fatigue damage initiation, evolution and termination of structural parts during fatigue tests.
Many academicians of Chinese Academy of Sciences and aerospace experts have commented that this achievement has made China step into the international leading level in the field of compiling load spectrum with high confidence, which will greatly promote the development of fatigue discipline, indoor simulation test technology, multi-axis combined action life estimation theory, and lay the foundation for the development of structural reliability simulation design in 2 1 century.
Responsible for designing and developing the first photoelasticity instrument and the first resistance strain instrument in China, and 1956 was awarded as an activist of Beijing youth socialist construction.
From 65438 to 0988, Gao successfully completed the research work of two scientific research topics, namely, "Helicopter strength specification and instructions for the use of helicopter strength specification" and "Research on fatigue fracture of aviation plexiglass and formulation of fatigue manual and fracture map". In the same year, the research topic of "fatigue life estimation under combined stress" was completed, which solved the fatigue life estimation problem of landing gear strut under combined stress. Since then, Gao has further improved the random fatigue fracture load spectrum and put forward the compilation method of random accelerated test spectrum, which saves a lot of money for fatigue test and improves work efficiency.
Since 1978, Gao has been a professor and director of the Institute of Solid Mechanics at Beihang University, and has undertaken more than 30 scientific research projects of the State, the Ministry of Aeronautics and Astronautics and the Air Force, all of which have achieved important results. Among them, 4 papers won the national achievement award, 9 won the ministerial achievement award, and 2 papers were rated as excellent papers of China Metal Society. 199 1 won the first prize of Guanghua Science and Technology Fund.

Personality assessment
As a teacher, Academician Gao always insists; There should be a spirit of sacrifice, because this is a fine tradition of China. As a teacher who preaches, teaches and dispels doubts, teachers should put students first in scientific research achievement awards and paper signatures. (Audited by the Capital Civilization Office)
Academician Gao is a climber on the road of scientific research, a soldier fighting for the motherland and the nation, and a tireless teacher. The influence of high personality charm on society lies not only in science and education itself, but also in his outstanding contribution to social civilization and progress.
