Abstract

The invention discloses a method and a device for braking a rotor of a helicopter ground joint test bench, and belongs to the technical field of helicopter comprehensive tests. Including: the master hand terminal arranged far away from the test site, the slave hand terminal arranged at the test site, and the control transmission system between the master hand terminal and the slave hand terminal; the master hand terminal is equipped with a master hand handle, displacement detection equipment, braking resistance Structural controller and brake resistance construction equipment; the slave hand end is equipped with an actuator controller, actuator, brake handle and brake resistance detection equipment; the mechanical displacement generated by the main hand end pulling the main hand handle is converted into an electrical signal by the displacement detection equipment , the electrical signal is transmitted to the actuator controller through the control transmission system to control the actuator to drive the brake handle; the brake resistance detection equipment detects the brake resistance in real time to generate an electrical signal, and transmits it to the brake resistance structure controller at the main hand end, which is controlled by the brake resistance structure controller The brake resistance construction device generates torque and feeds it back to the operator.

Description

technical field [0001] The invention belongs to the technical field of helicopter comprehensive tests, and in particular relates to a rotor braking method and device for a helicopter ground combined test bench. Background technique [0002] The helicopter ground joint test is an important test method to verify the function, performance and durability of the three major moving parts of the helicopter rotor, transmission, and power system. The rotor brake device is one of the important components of the helicopter ground joint test bench. [0003] Helicopter ground joint test The ground joint test cycle is long. If the pilot performs the rotor brake operation, it needs to coordinate and occupy scarce helicopter pilot resources for a long time. The boring and long-lasting test will easily cause driver fatigue and increase the risk of misoperation. A compromise solution is that when the rotor brake is required, the operator performs the braking operation from the measurement and...
