Abstract: In order to solve the problems of difficult installation and poor maintainability of aircraft mechanical emergency braking,an electric-controlled emergency braking system is proposed in the paper. The electric-controlled emergency braking system is mainly composed of electric-controlled emergency braking valve and local energy components and other key components. The model of the electric-controlled emergency braking system and its key components are established and simulated based on AMESim. The test platform of the electric-controlled emergency braking system is established to test and verify the system functions and the performance of the key components. The simulation and test results show that the electric-controlled emergency braking system has complete function and the design of the key components is reasonable. The research results can provide reference for the design of new electric-controlled emergency braking system of aircraft.
