On December 4, the plastic molding and mold technology expert and Professor Shen Changyu of Zhengzhou University was elected as a member of the Chinese Academy of Sciences. He is a native of China's "after 60" academician and the youngest academician in Henan Province.
Shen Changyu was born in Nanyang, Henan Province in June 1963. At the age of 17, he was admitted to the People's Liberation Army Railway Engineering College. After graduating in 1984, he entered Dalian University of Technology. In 1987 and 1990, he received a master's degree in engineering and a doctor of engineering degree from Dalian University of Technology. In August 1990, Shen Changyu returned to his hometown of Henan and became a teacher at the former Zhengzhou Institute of Technology. It is this ordinary teacher that opened a new chapter in the field of plastic molding and mold technology in China.
Mould is known as the mother of industry in developed countries, and its technical level is an important indicator of a country's industrial manufacturing level. Since the reform and opening up, China's mold industry has developed rapidly and the total number of molds is among the highest in the world. However, the application of some high-, precision- and micro-structured functional products and new materials has not been resolved. High-grade plastic molds and high value-added rubber and plastic products are also major Depends on imports.
How to make plastic molding and mold design based on scientific analysis and quantitative calculation, realize the optimal design of the mold and precise control of the molding process, is a bottleneck in the field of plastic molding and mold technology, but also whether China can be transformed from a manufacturing country into a The key to making a strong country.
For more than 20 years, Shen Changyu has conducted systematic research on key theoretical and technical issues in plastic molding and mold technology. As early as in 1987, under the mentor's guidance, Shen Changyu began research on the numerical simulation and optimization design of the injection mold cooling system, and developed an optimization design program for the injection mold cooling system based on sensitivity analysis. After working in 1990, Shen Changyu and several teachers established a mold research institute and started systematic research on the principles of numerical prediction and efficient algorithms for filling, curing and residual stress of injection molding. In just two years, the Institute has become a provincial research center. In 1993, after six rounds of expert review, Shen Changyu led the establishment of a National Research Institute of Rubber and Plastic Mold Engineering with a total funding of nearly 60 million yuan. This is also one of the 47 national engineering research centers in China that were built using World Bank loans.
Satisfying National Urgent Needs In order to predict and regulate the structure and performance of products, Shen Changyu conducted a series of experimental studies, numerical simulations, and mechanistic analysis of the formation and evolution of micro-structures under the action of complex flow and thermal fields in the plastic molding process. In order to realize the optimization of molding process control and mold structure design, he conducted research on the optimization of injection mold design, molding process and product quality control methods based on simulation, and developed efficient and practical plastic molding process control and plastic mold optimization design models. algorithm. As the first finisher, the related achievements won the 2003 National Science and Technology Progress Award.
In 2005, Professor Shen Changyu took charge of the development work of the Shenzhou 7 astronaut's cabin space helmet window and related plastic parts. After three years and nights of hard work, helmet-mounted windows made in China passed acceptance. This high-impact, high-spectrum transmission, low stress, and “no†side window product with a 300°C temperature difference fully meets aerospace requirements. At 16:34 on September 27, 2008, our country’s astronauts walked out of the cabin for the first time in a space suit developed by China and realized the Chinese people’s dream of traveling in space for thousands of years. The research team of the National Rubber Mold Engineering Research Center of Zhengzhou University has also won the Outstanding Contribution Award for the 2008 China Manned Space Project.
Establishing higher goals Over the years, Prof. Shen Changyu has directed or completed major projects of the National Natural Science Foundation of China, the National Science Fund for Distinguished Young Scholars, the Climbing Plan, the Space Program, the “863†Plan, and the State’s “Eighth Five-Year Plan†around plastic molding and mold technology. There are more than 20 major research projects at the national and provincial (ministerial) level such as the "9th Five-Year Plan" and "10th Five-Year Plan" and the "Eleventh Five-Year" Support Plan.
Although he has made numerous achievements, Shen Changyu is still as modest and prudent as before. He said: “This time we were able to become an academician of the Academy of Sciences. It is an opportunity provided by the country’s training and era, and it is also the support and support of seniors, teachers, colleagues, and family members. As a result of the collaborative effort, for me, the elected academician is not only an honor but also a responsibility, which means that I will use a higher standard to demand myself. I will use this election as a new starting point and new Motivation, strive to make new achievements."
