Among them, freight trucks are an important part of the transportation industry. The frame is an important component of the freight truck, which bears the weight of the entire vehicle and the quality of the cargo. Due to the inevitable influence of factors such as road surface bumps and suspension system reaction forces during the operation of the freight truck, the frame is in a continuous vibration state. Vibration not only affects the comfort of the driver, but also affects the stability of the vehicle. When it is serious, it can also cause frame damage. Therefore, it is important to study and analyze the vibration characteristics of the freigh...
