Test equipment and test method for rolling control of main flight control cockpit device

Abstract

The invention discloses test equipment for rolling control of a main flight control cockpit device; the test equipment comprises two steering wheel rod force test devices and two steering wheel angle test devices; the two steering wheel rod force test devices are correspondingly mounted on the front end surfaces of a left steering wheel and a right steering wheel respectively; the two steering wheel angle test devices are correspondingly installed on rotating shafts of a left steering wheel and a right steering wheel respectively, the positions of the two steering wheel rod force test devices correspond to the positions of the two steering wheel angle test devices in a one-to-one mode, and the control characteristics of a cockpit control system are tested and adjusted. The test equipment has the advantages that a steering wheel testing fixture A and a steering wheel testing fixture B are designed and manufactured by using a curved surface design instead of performing supplementary processing on a product and replacing the product with a fake part, so that the steering wheel testing fixture A and the steering wheel testing fixture B are tightly connected with a steering wheel, and the authenticity of system testing is ensured.

Description

technical field [0001] The invention belongs to the technical field of a main flight control cockpit control system, and relates to a test device and a test method for the roll control of a main flight control cockpit device. Background technique [0002] The main flight control cockpit device is the control equipment of the fly-by-wire flight control, including pitch control, roll control and yaw control devices. The pilot's driving command is converted into an electrical signal through the module four-redundant RVDT and output to the flight control computer to realize control. Aircraft attitude control. At the same time, since the aerodynamic load on the rudder surface of the aircraft will not be transmitted back to the cockpit control mechanism, the torsion spring assembly in the module must provide the pilot with a sense of control force and return to the center function, and provide a damping effect through the damping motor. The trim actuator provides an anchoring ful...

Problems solved by technology

[0003] In the past, similar test methods required supplementary processing of the product to ensure its installation interface, but such methods destroyed the structure of the product itself and had an impact on the stiffness and strength of the system, so it could not truly reflect the system characteristics. At the same time, some test methods will 4 The components that are not easy to connect, such as the steering wheel, are replaced by fake parts, but the fake parts are structurally different from the product itself, so they cannot truly reflect the system characteristics

[0004] At present, there is a lack of test methods for the roll control of the main flight control cockpit device, and it is impossible to verify the performance indicators of the roll channel
