The invention discloses a commercial vehicle vertical nonlinear vibration modeling method considering a flexible frame. The commercial vehicle vertical nonlinear vibration modeling method specifically comprises the following steps: 1) establishing a flexible frame vibration model; 2) establishing an unsprung mass vibration model; 3) establishing a continuous deceleration strip excitation model; 4) establishing a commercial vehicle vertical nonlinear vibration model considering a flexible frame; and 5) calculating the vertical nonlinear vibration of the commercial vehicle. The method has the beneficial effects that the method integrates a flexible frame, suspension rigidity and damping nonlinearity, suspension bushing rigidity and damping and continuous deceleration strip road surface excitation factors to analyze the vertical nonlinear vibration characteristics of the commercial vehicle under the factors such as vehicle speed and deceleration strip height; the method can improve the accuracy of analysis of ch
