With the development of automobile industry, the timing chain transmission system of automobile engine has been more and more widely used and has a broad market application prospect. However, there is still a gap between the performance of domestic car chain and foreign products at high speed. at present, most of the timing chain systems of domestic engine main engine factories use foreign products, which seriously restricts the development of domestic independent brands. In order to improve the independent development and design ability and manufacturing level of the timing chain system, the working characteristics and design methods of the timing chain system need to be studied in detail. In addition, with the development of computer technology, computer-aided design and analysis are widely used in engineering. For the timing chain system, engineers can analyze the dynamic characteristics of the developed system by using the more mature analysis software in the market, and evaluate the designed system according to the analysis results, but because the layout of the timing chain system is different, the working conditions are also different, so it is difficult to design and develop the system. At present, there is no software platform for engineers and technicians to design and develop the timing tooth chain system in the market.
