| description | The invention provides an air suspension whole vehicle dynamic response resolving method and related assemblies. The method comprises the steps that a whole vehicle nonlinear seven-degree-of-freedom model is established; establishing a four-wheel pavement excitation model; calculating the equivalent amplitude of the air suspension based on the whole vehicle nonlinear seven-degree-of-freedom model and the four-wheel pavement excitation model; calculating the equivalent stiffness and equivalent damping of the air suspension based on the equivalent amplitude of the air suspension; and based on the air suspension equivalent stiffness, the air suspension equivalent damping and the whole vehicle nonlinear seven-degree-of-freedom model, calculating the whole vehicle dynamic response of the air suspension. According to the method for resolving the dynamic response of the whole vehicle with the air suspension, the amplitude correlation of the air spring is considered, and the dynamic characteristics of the whole vehic |
