In order to inspire the members' ideas, expand their horizons, and enrich the content of this annual meeting, academic exchange activities were arranged. Wu Yizhen, deputy director of the National Belt and Belt Standardization Technical Committee, made a report on the status quo of development of domestic and foreign belt transmissions. The paper comprehensively introduced the development situation of domestic and foreign belt transmissions, and clarified the opportunities and challenges facing China's belt transmission field. Belt companies understand the international belt drive development trends and provide good materials. The conference specially invited the representative of South China University of Technology, Shangguan Wenbin, to make a report on "Vibration Control of Front-end Attachment Drive System of Automotive Engines", conducted a large number of experiments and simulations through theoretical analysis, and expounded the tension force, speed and vibration during belt drive , Slip, noise, and propose a practical solution, which provides new ideas for the practical application of the belt. Finally, Professor Li Zhanguo, the chairman of the National Technical Committee for Standardization of Belt Wheels and Belts, made a report entitled "Test and Analysis of the Lateral Swing Amount of Automobile Timing Belt Drives." It is of practical significance to provide optional parameters for enterprises to improve the quality of the belt.
According to the "Administrative Regulations of the National Professional Standardization Technical Committee" formulated by the National Standardization Management Committee in 2009 and the charter of the National Technical Committee for Synchronous Belt and Belt Standardization and its technical committees, the Standardization Committee, the Deputy Chairman and the Secretariat have studied and decided From November 25th to 29th, 2009, the second annual meeting of the National Technical Committee for Belt and Belt Standardization and the Technical Committee for Timing Belt Transmission and the Technical Committee for Friction Belt Transmission was held in Zhuhai, Guangdong Province. More than 60 members and invited representatives attended the meeting.
During the meeting, the participating members reviewed the submission standard for the chemical industry standard "Narrow V-belt" and sought opinions on the national standard "V-ribbed belt for home appliances". After hearing the draftsman's introduction to the main standards development process, the participating members reviewed the draft standards chapter by chapter, and discussed them thoroughly during the review process, and proposed some amendments and suggestions to the standards based on consensus. The participants fully affirmed the large amount of work done by the standard drafting unit in the standard setting work, and finally unanimously passed the review of the standard submitted by the "Narrow V-Band" for review.
The opening ceremony of the annual meeting was welcomed by Jiang Hongyuan, deputy chairman of the National Technical Committee for Timing Belts and Belts, and the meeting was chaired by Wu Yizhen, deputy chairman of the National Committee for Belts and Belts Standardization Technology. Director Li Qin of the China Machine Productivity Promotion Center attended the meeting and delivered a speech. Director Li expressed his satisfaction with the work of the bid committee in 2009 and explained the importance of standardization from different perspectives. He said that he would support the work of the bid committee as always. Qin Shu'an, Secretary-General of the National Technical Committee for Belt and Belt Standardization, made the 2009 Annual Work Report and 2010 Outlook for the National Technical Committee for Belt and Belt Standardization and the Technical Committee for Timing Belt Transmission. Encouraging results have not only successfully completed the set tasks, but also undertaken the work of the Secretariat of the International Organization for Standardization Belt and Belt (ISO / TC41), which has taken a solid step for China's belt standardization to go international and fight for the right to speak internationally. Sun Guangming, Secretary-General of the Friction Belt Transmission Sub-Committee, made the annual report of the chapter, and systematically summarized the work of the year. Huang Gang, secretary of the National Technical Committee for Belt Wheels and Belts, reported the ISO / TC41 International Annual Meeting in France. Finally, Zhou Yujie, the secretary-general of the Technical Committee for Timing Belt Transmission, explained the specific content of the "Administrative Regulations of the National Professional Standardization Technical Committee", which made the participants clearer of their responsibilities and laid a good foundation for future work.
