What stage is the research of pneumatic butterfly valve for commercial vehicles at present
The research on pneumatic butterfly valves for commercial vehicles started late in China. The products of domestic pneumatic butterfly valve manufacturers are relatively single, the scope of application is narrow, and the product quality is poor compared with imported products. Therefore, most domestic commercial vehicle manufacturers use imported pneumatic butterfly valves. At present, many pneumatic butterfly valve manufacturers in China are absorbing and improving the relevant technology of pneumatic butterfly valve, developing and producing commercial vehicle pneumatic butterfly valve products with independent intellectual property rights and suitable for China's road transport characteristics. At present, some pneumatic butterfly valve products have approached or reached the quality standards of international similar products.
The pneumatic butterfly valve has excellent elastic performance, which can significantly improve the comfort performance of the vehicle when applied to the vehicle suspension system. Therefore, the research on the pneumatic butterfly valve at home and abroad at this stage is very important. With the rapid development of computer technology and the continuous maturity of finite element calculation theory, the research and development of pneumatic butterfly valves at home and abroad has turned to the channel of combining computer virtual design and test. It has been proved that the virtual manufacturing design method can quickly and clearly construct a predetermined scheme on the computer, repeatedly simulate various extreme conditions in a short time without taking corresponding risks, and provide detailed and feasible technical schemes for design departments and production units. The stiffness of pneumatic butterfly valve is tested through experiments, and the stiffness characteristics of pneumatic butterfly valve are analyzed by finite element method using virtual software.
