The axle and suspension are critical components of vehicles. To achieve real-time simulation of the solid axle and various suspension structures of a commercial vehicle，the property-based modeling technical route is adopted in this paper. The axle's movement is decoupled into motion kinematics and ride dynamics，while the suspension characteristics are divided into coupled carrying characteristics，RC/PC guiding characteristics，and coupled K&C kinematic characteristics. Innovatively considering the pitch dynamic effect of the axle，the nonlinear dynamic coupling relationship of suspension between axles，and the K&C coupling relationship of suspension between axles，a dynamic model for commercial vehicles is developed to trigger the negative phenomenon of brake vibration. Additionally，a K&C testing method for the coupled suspension and a method for model parameter identification are proposed. Finally，the accuracy of the model is validated at the system level by comparing K&C test data with TruckSim model results. Inputting vehicle parameters into the UniTruck software for simulation and comparing the results with TruckSim simulation，the model’s effectiveness is verified at the vehicle level.
