As an important component of modern urban public transportation,the safety of escalators is directly related to the safety of passengers'lives and property.The additional brake,as a key safety device of the escalator,can quickly stop the escalator in case of overspeed,reverse,or main drive chain breakage,ensuring passenger safety.It establishes a numerical simulation model for the entire elevator,applies braking load and braking torque,simulates the braking process,and analyzes it.The comparison between the simulation model and the field test results shows that the step vibration parameters of the simulation model during the braking process are consistent with the field test results,which verifies the effectiveness of the simulation model.
