Application of Leaf Springs in Construction Industry

The application of leaf springs in the automotive industry and their application in machinery is widely known. However, no one is interested in the use of leaf springs in the construction industry.

In October 1999, Prof. Xu Guobin of Beijing Jiaotong University, in the design of the Guangzhou New Gymnasium (9th National Games Project), for the first time explained to the French ADP company the use of their national patented products: "universal bearing, universal rotation, and seismic reduction." The “vibration-resilient spherical steel bearings” can solve insurmountable design problems [1] in the project roof design, develop their third-generation bearing products, and push the application of leaf springs to the construction market. The design, manufacture and processing of leaf springs were completed by Beijing Shougang Hongye Steel Works.

First, the question is raised Second, the basic requirements of the leaf spring, the design process and the difficulty analysis Third, the design and manufacturing process improvement Fourth, the direction of future efforts

Author brief introduction Wang Jun, currently serves as the chief engineer of the leaf spring plant of Beijing Shougang Hongye Steel Plant, and a senior engineer in metal materials and heat treatment. Currently it is a member of the National Spring Standardization Technical Committee.

Work resume 1979 January ~ January 1983, the first branch of the Beijing Iron and Steel Institute metal materials and heat treatment, a bachelor degree in engineering;

In March 1983, it was assigned to the Shougang Hongye Steel Plant, mainly engaged in product development and daily management of automotive leaf springs;

In 1989, he was appointed deputy section chief of technology development section of Shougang Hongye Steel Plant;

In 1990, he was the chief of technology development section of Hongye Spring Plant of Shougang Corporation;

In 1992, he was appointed Deputy Director of the Institute of Leaf Springs at Shougang Hongye Spring Plant.

From 1993 to 1998, the new product development of leaf spring was carried out at the technical department of Shougang Hongye Steel Plant.

From October 1998 to now, he served as the chief engineer (Chief Engineer) of the leaf spring plant of Hongye Steel in Shougang. To undertake the review of the new product development of leaf springs and related new product development and scientific research work.

During the “6th Five-Year Plan” period, the company participated in the research and development of 28MnSiB new low-carbon spring steel and participated in the development of a variable-break panel spring. The National Science Committee and the Ministry of Metallurgy issued a major achievement award for this purpose.

Since 1984, he has conducted technical negotiations with foreign companies several times, designed and developed a variety of export leaf springs, and exported large quantities to the United States, Canada, and the United Kingdom, achieving very good economic benefits. At the same time, due to long-term work in the production line, accumulated a lot of on-site processing experience. It has won several awards from the relevant departments of Shougang Corporation for export earnings.

From 1998 to 1999, due to the successful application of the hardenability test to the production of leaf springs prior to rolling, a large amount of waste products that were originally caused by poor material hardenability were avoided, thus obtaining the best operator of Shougang Corporation, and at the same time The third prize for the best operation method.

In 2000, due to the successful design and development of the new leaf spring required for the Guangzhou New Stadium (the Ninth National Games Project, the closing ceremony was held here), the Beijing Federation of Trade Unions awarded the honorable title of economic and technological innovation model. This kind of leaf spring is used in the construction industry for the first time in the world. It is taught by Northern Jiaotong University Professor Xu Guobin (Ph.D. supervisor, member of the expert group of China Steel Association, director of the China Steel Association of Space Structure Association, a national first-level registration The structural engineer proposed that the technical parameters proposed by Tongji University be completed by me from the beginning of design to the entire process of production and inspection.
