Abstract: In order to solve the problem of automobile brake performance testing, this paper studies the testing mechanism of flat plate brake test bench. Using CarSim-Simulink co-simulation method, the simulation calculation model of flat plate brake test bench is established, and the accuracy of the model is verified by standard test. The model error is within ±5%, which can accurately reflect the change of front and rear axle braking force when different vehicles are braking. Based on the verified simulation model, the axle load transfer of the vehicle during braking is further studied. With the increase of the load, the maximum braking force and the maximum axle load transfer increase.
