AMESim software was used to model the braking system of the suspension monorail train.The braking time,braking distance and braking deceleration in the full service braking,fast braking and emergency braking trains under three load conditions,namely,AW0,AW2 and AW3,were simulated and analyzed,and the impact rate of the train braking was calculated.The results show that applying hydraulic braking force in advance for a certain time can effectively improve the phenomenon of excessive braking impact rate in the process of switching between electric braking force and hydraulic braking force.
