Development and Design of Transmission Gear Tooth Surface Contact Area Based on MASTA Finite Element Software Xu Hongbin\Jia Peng\Li Peijun 2 (1.Chongqing Institute of Technology Vehicle Engineering Institute, Chongqing 400050; 2. Chongqing Qingshan Industry Co., Ltd., Chongqing 402761) The gear is the key component of the transmission... This article uses the finite element analysis software|MAS Ding A powerful tooth contact analysis function to calculate the CAE simulation of the tooth surface contact area of ​​the transmission and transmission gear pair of the vehicle transmission. | Over gear pair hobbing contact.
In general, the actual tooth surface contact area obtained through the experiment is basically consistent with the theoretical contact area obtained by CAE simulation analysis. The test results can fully prove the correctness of the previous simulation analysis.
2 CAE simulation analysis and experimental verification of the gear tooth surface contact area of ​​the transmission drive train. According to the design and construction scheme of the transmission gear train, the design sub-function module of the finite element analysis software MASTA is used to establish the limited transmission gear wheel drive system. The meta-analysis solid model is applied to the powertrain model through the Loadcases sub-module. (1) The gear tooth surface contact area of ​​the drive train is verified by the combination of CAE simulation analysis and experimental verification on the gear tooth surface contact area of ​​the transmission drive train. The distribution is reasonable, the overall design of the transmission gear train is reasonable, and the work performance is safe. B. Beijing: Mechanical Industry Press, 1995, 4. Wu Daren, Luo Jiayu.

Welcome to the comprehensive academic journals published by the 2007 "Journal of the Fourth J丨丨兵工" and the Chongqing (Sichuan) Institute of Armed Forces, published domestically and continuously, the domestic unified serial number: CN50-1088/TJ, International Standard Serial Number: ISSN1006-0707. Since its inception 26 years ago, the magazine has always adhered to the tenet of “serving the military industry and serving the scientific and technological personnel” and actively promoting the important idea of ​​“science and technology are the primary productive forces”. Well-known schools and well-known experts and scholars inside and outside the industry wrote and published a large number of papers by scientific and technological workers, which played a positive role in promoting the scientific and technological progress of the weapons industry.
Over the years, the journal has always received the care, support and love of the authors and readers, and has achieved continuous development and progress. It has become a journal of China's core journals (selection) database, Chinese scientific papers, statistical source journals, Chinese science and technology journals. The full-text journal of the database, the journal of the CNKI China Journal Full-text Database, and the source journal of the comprehensive evaluation database of Chinese academic journals.
In the new year, under the guidance of the academicians of Cai Hongnian and Duo Yingxian, under the direct leadership of the editorial board, the journal will be held at Chongqing Institute of Technology, Chongqing University, Beijing Institute of Technology and Nanjing University of Science and Technology. With the strong support of the colleges and universities, we constantly improve the content and layout, and strive to develop our own characteristics, so that they can continue to become the staff of scientific and technological innovation, the assistant of scientific management, the window of military information and the booth of modern weapons.
Monthly magazine, each book is priced at 10 yuan, and the annual price is 60 yuan.
