Problems solved by technology
[0002] The automobile fuel supply system is the source of automobile power. Among them, the support device of the fuel tank bears the weight of the fuel tank. Once it breaks, it will directly cause the fuel tank to fall off, the power source is interrupted, and it is easy to cause traffic accidents, especially for poor driving conditions. For engineering vehicles, the impact on the road surface is large, and the working environment of the fuel tank bracket is even worse. Therefore, during the product development process, the durability performance of the fuel tank assembly is assessed to make it meet the use requirements of the vehicle and improve the fuel supply system. reliability is essential
