Character experience

On October 17, 1917, Yang Ji (nicknamed Junpu) was born in Beijing and his ancestral home is Jurong County, Zhenjiang, Jiangsu Province.

In 1930, he was admitted to Guangzhou Peizheng middle school. There were many ships going from south to North in Guangzhou. Since then, he has been fascinated by ships and wrote an article entitled "history of Guangdong shipbuilding".

In 1935, he graduated from Guangzhou Peizheng middle school, went to study in England and was admitted to the shipbuilding Department of Glasgow University. During this period, every summer vacation I went to Barker shipyard in England to receive apprenticeship and draftsman training.

In March 1940, he graduated from the Department of shipbuilding of Glasgow University in England with a first-class honorary bachelor's degree. After returning to China in May, he successively served as a lecturer of Tongji University, an assistant engineer of Chongqing Minsheng machinery factory, a teacher of Chongqing merchant shipping school (formerly Wusong Merchant Shipping College, but now the predecessor of Dalian Maritime University due to the war) and a professor of shipbuilding Department of Jiaotong University.

From 1940 to 1944, he served as Deputy Engineer and engineer of Chongqing Minsheng Machinery Factory; Lecturer of Tongji University; teacher of Chongqing Merchant Shipping College (formerly Wusong Merchant Shipping College, moved in due to the war and now the predecessor of Shanghai Maritime University); Professor of Jiaotong University.

In November 1944, as a member of the Chinese Navy's service group to the United States, he visited and practiced in shipyards and related schools on the east coast of the United States. He also served as an assistant supervisor at the U.S. Navy shipyard in Philadelphia to supervise shipbuilding and ships. He learned a lot of experience in ship design and construction, production planning management, engine repair, etc.

In January 1946, after returning to China, he successively served as an engineer of Jiangnan Shipbuilding Institute of the Navy, director of Public Works section of Qingdao Shipbuilding Institute of the Navy, and Dean of Shanghai naval machinery school.

After the founding of the people's Republic of China in 1949, he successively served as professor of Tongji University, director of shipbuilding department, director of public works of Dalian Shipyard Committee, deputy chief engineer of Sino Soviet shipbuilding company, engineer of Preparatory Office of Bohai Shipyard, Professor of Dalian Institute of technology and director of shipbuilding Department.

In 1955, after the shipbuilding Department of Dalian Institute of technology was merged into Shanghai Jiaotong University, he successively served as the deputy dean of Shanghai Jiaotong University, the dean of Shanghai Shipbuilding college, the deputy dean of Shanghai Jiaotong University, the dean of shipbuilding department.

In September 1978, Shanghai Jiaotong University established the Institute of ship and ocean engineering with Yang Ji as its director.

In May 1980, he also served as the vice president of Zhenjiang Institute of shipbuilding (East China Institute of shipbuilding, now Jiangsu University of science and Technology).

In November 1981, he was elected member of the Department of technology and science of the Chinese Academy of Sciences.

In 1984, he was elected as a member of the discipline evaluation group of the Academic Degrees Committee of the State Council and the leader of the discipline evaluation group of Ship Engineering (including Ocean Engineering). Doctoral supervisor of ship design discipline.

In September 1978 and May 1980, he visited Japan as the deputy head of the Chinese marine science delegation and the deputy head of the Chinese society of Shipbuilding Engineering delegation, respectively. In May 1982, he went to the UK as head of the delegation to attend the International Conference on ship system design.

In 1984, as a member of the Shanghai Municipal People's Congress delegation, he visited Osaka Prefecture, a Japanese friendly city. He was the honorary chairman of the ship History Research Association, which was founded in 1984 and the journal ship history research in 1985.

In 1986, he visited the United States as a member of the Advisory Committee of the International Conference on Offshore Mechanics and Polar Engineering.

In 1990, he was invited to give lectures at Osaka Prefectural University in Japan. In order to show concern for China's shipbuilding industry, Yang Zhen once submitted a proposal to the National People's Congress for a scientific investigation of the "Bohai No.2" capsizing accident, which has attracted the attention of the government and relevant departments.

From December 1992 to December 1997, he became the first president of Shanghai Shanda University.

Main achievements

Achievements in scientific research

Yang Ji presided over and participated in the design of patrol boat "Yingzhou", 15000 ton self unloading coal carrier, 5000 ton ocean dry cargo ship, 15000 ton economic ocean dry cargo ship, etc. He presided over and led the formulation of China's first "code for stability of sea going ships", which promoted the research work of China's ship stability. Since 1963, he has directed postgraduates to carry out a large number of systematic experimental research on passive anti rolling silos, and the research results have been widely used by design and research units. In the mid-1970s, he began to engage in the research of technical and economic demonstration of water transportation and ocean engineering system, which promoted the development of this science in China. First of all, we initiated the development of the computer integrated system for the design of offshore cargo ships. The main dimension analysis program and the profile design program compiled by us have been incorporated into the system, which has made an important contribution to the development of the computer-aided design of shipbuilding science and technology in China.

In 1960, he presided over the formulation of China's first code for stability of seagoing ships. The formulation of the code not only initially changed the passive situation of China's previous non ship survey code, but also put forward dozens of research topics, which further promoted the research work of ship stability in China.

In 1962, he wrote a brief history of the development of China's shipbuilding industry, which describes the development process of China's ancient and modern shipbuilding industry, as well as the way to success or failure. When this paper was read out at the first academic annual meeting of Chinese society of shipbuilding engineering after the founding of new China in 1962, it caused great repercussions. Later, he advocated that the shipbuilding industry should pay attention to the study of Chinese shipbuilding history, so as to make the past serve the present, and sum up and draw lessons from the historical experience, so as to accelerate the development of China's contemporary shipbuilding industry.

In December 1965, his graduation thesis "model test of passive anti rolling tank and its application in design" was completed by his graduate student, which became an important reference for ship design department to design passive anti rolling tank. The 15000 ton self unloading coal carrier is a new ship type pre research work which he instructs the graduating class students to carry out. Through a number of studies on the ship's coal unloading device, coal bunker layout and coal hopper oscillation device, it is considered that it is feasible to build this type of ship in China at that time, and a ship model was made. In the 1980s, China's shipping and shipbuilding departments confirmed that this type of ship has certain advantages for China's coastal coal transportation. The 5000 DWT economical dry cargo ship is a ship type developed by him in the mid-1970s in cooperation with the Shanghai Institute of Ship Transport Science, Ministry of communications. At that time, he led graduate students to Fuzhou, Xiamen, Shantou, Guangzhou and other coastal ports and some ships to carry out extensive and in-depth investigation and research, analyzed the relevant data of the same type of ships at home and abroad, and made a detailed analysis of the ship's service speed, cabin layout and ballast in view of the rising fuel prices and the poor seaworthiness of this type of cargo ship when it was empty. Part of the research work has been praised by Shanghai Ship Design Institute, which undertakes the technical and construction design of this type of ship. The ship was put into operation in batches in the 1980s.

With the development of international shipping industry in 1970s, the economy of shipping is particularly important. If the economy of shipping is taken into account in ship design, it is possible to build a ship with low cost and in line with the requirements of the orderer, so as to make it more competitive in the world. Based on his long-term experience in ship design, Yang Zhen vigorously advocated and engaged in the research of ship technical and economic demonstration methods in the mid-1970s. The scientific research group led by him cooperated with relevant research units to carry out technical and economic argumentation for 5000 DWT dry coastal cargo ships and 15000 DWT ocean going cargo ships, and compiled computer programs.

Since the mid-1980s, he has directed graduate students to engage in the analysis and research of coastal and Yangtze River coal, oil and container transportation systems, aiming at selecting the optimal ship type and fleet composition. In the analysis, not only the cooperation of ship, port and channel, but also the marine weather, operation efficiency and many uncertain factors in operation cost are considered. His research team applied modern forecasting technology, operational research and system analysis methods to solve the problems of ship type analysis and fleet planning in water transportation system. In addition, his research team has made some successful explorations on the dynamic simulation of the operation of the water transport system by using computers.
