Description

technical field [0001] The invention relates to a connecting cable between an aircraft electric brake controller and an electromechanical actuator. Background technique [0002] The aircraft braking system is a subsystem with relatively independent functions on the aircraft. Its function is to absorb the kinetic energy of the aircraft during landing and taxiing, so as to make the aircraft brake quickly. The all-electric braking system is to use the electronic drive device to drive the brake actuator, and use the electronic transmission line to replace the original oil pipeline to realize the braking and control functions of the brake. [0003] The all-electric braking system has better safety, reliability, maintainability and potentially better braking performance and can greatly reduce the weight of the system. However, it also brings many problems, among which the problem of electromagnetic interference is one of them. [0004] Brushless DC motor (BLDCM, Brushless DC Mot...

AI Technical Summary

Problems solved by technology

[0007] At present, the research in the field of all-electric braking mainly focuses on the anti-skid control rate and motor control method, but ignores the discussion on electromagnetic compatibility. The aircraft all-electric braking system includes both the motor drive signal that generates strong interference and weak position feedback. Signals in one cable will inevitably cause serious electromagnetic interference problems, which will seriously affect the control accuracy of the system. However, domestic aircraft electric brakes are still in the development stage, and the connecting cables used have not been processed.
