| Abstract: | A new vehicle air power brake system(ABS & APB) is put forwarded in this paper to resolve that the braking distance can’t be effective curtailed because of the maximum ground braking force during four-wheel farm vehicle braking.We analyzes its working principle and research on the basic simulation of control model.The academic feasibility of initiative air power brake system is expatiated,that is basing on the principle of compressed air power reaction which is applied to the brake system,then establishes dynamics model of a new four-wheel farm vehicle brake system and simulation model of ABS & APB base on Simulink.In this paper,the simulated tests are designed to compare with the curve of vehicle speed and wheel velocity with APB to reduce braking distance and braking time. |
