Abstract

The invention belongs to the control technique of mechatronic systems, and relates to an improved simulation system of brake experiment inertia of the traditional airplane. The system comprises an inertia disk, a motor, a transducer, a moment sensor, a rotation coder, and the like. The simulation system of brake experiment inertia of the traditional airplane adopts translation inertia of a rotation inertia simulation airplane with a mechanical inertia disk with fixed mass, the system has large volume and difficult inertia adjustment, and the brake system of a specific mass airplane is experimented only. Aiming at the problems, the simulation method of the brake experiment electric inertia of the airplane is provided. The method can realize the electric simulation of the mechanical inertia, and can smoothly adjust the whole inertia of the experiment system, thereby being capable of testing brake systems of the airplanes with different masses. The method can also compensate residual push power, pneumatic resistance and front wheel friction of an engine of the airplane during the brake. The research result provides an effective method for the inertia simulation of the airplane during the brake experiment, saves huge fund, and has ingenuity and remarkable economic benefit.

Description

technical field

[0001] The invention belongs to the electromechanical system control technology and relates to the improvement of the inertia simulation system of the traditional aircraft braking experiment. Background technique

[0002] As an important airborne equipment, the aircraft braking system has an important impact on the safety of the aircraft's take-off and landing. The inspection of its performance and quality is an important measure to ensure the safety of the aircraft. Usually, the aircraft brake test bench uses a large-diameter inertial disc to simulate the runway, and converts the translation of the aircraft into the rotation of the inertial disc to simulate the actual working conditions of the wheels during the braking process of the aircraft. Various parameters of the aircraft tires and brakes under the pressure and other parameters, so as to test the various indicators of the tested wheel.

[0003] Because the mass of the inertia disk of the aircraft bra...
