Problems solved by technology

[0004] The design of the test scheme and the construction of the platform are particularly important. The predecessors proposed to use a stepping motor as the power to drive the turntable to rotate to simulate the rotor effect. The advantage of this method is that it can conveniently control the speed and maintain the stability of the structural dynamic characteristics, so as to test the structural dynamic characteristics. , however, the impact of the connection gap and the additional mass of the motor on the test has become a problem that is difficult to solve

Abstract

The invention provides a system for measuring and controlling a rotating speed. The system mainly comprises a photoelectric speed measuring device 60, a light sensing sheet 61, a data acquisition instrument 62 and an electromagnetic brake 50, wherein the light sensing sheet 61 is arranged at an end part of a rotating shaft 12; the photoelectric speed measuring device 60 and the light sensing sheet 61 are arranged correspondingly; and the electromagnetic brake 50 penetrates the rotating shaft 12, and is arranged on the rotating shaft 12 on the other side opposite to the light sensing sheet 61.

Description

technical field [0001] The invention belongs to the field of aircraft design, and in particular relates to a rotational speed measurement control system of an aircraft engine rotor effect simulation device using a non-contact power source as power. Background technique [0002] The design of modern large passenger aircraft widely adopts the layout form of hanging the engine under the wing. In terms of structural layout, this kind of hanging engine is often far away from the root of the wing and extends out of the leading edge of the wing. Due to the flexibility of the wing and the engine hanger, when the wing When torsional vibration and in-plane bending occur, the rotation axis of the engine rotor will vibrate in pitch and yaw angles. According to gyroscope theory, the angular motion of the axis of the rotating body will cause gyro torque, that is, the rotor effect; this rotor effect is bound to The system composed of the aircraft wing and the engine and even the structural...
