Abstract

An embodiment of the invention relates to the technical field of aero-engines, and discloses a calibration method, device and system of an adjustable guide vane and a computer readable storage medium.In the calibration method, device and system of the adjustable guide vane and the computer readable storage medium, the adjustable guide vane is driven by an actuator cylinder; the target calibrationvalue of the angle of the adjustable guide vane is obtained, and the angle of the adjustable guide vane and the position of the corresponding actuator cylinder are obtained; when the difference between the angle of the adjustable guide vane and the target calibration value is not within the preset range, the angle of the adjustable guide vane is adjusted according to the difference between the angle of the adjustable guide vane and the target calibration value until the difference between the angle of the adjustable guide vane and the target calibration value is within the preset range; and when the difference between the angle of the adjustable guide vane and the target calibration value is within the preset range, the angle of adjustable guide vane and the position of the correspondingactuator cylinder are recorded to complete calibration of a target calibration point. Automatic calibration of the adjustable guide vane can be realized, and the characteristics of high efficiency andhigh precision are achieved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of aero-engines, and in particular to a method, device, system and computer-readable storage medium for calibrating an adjustable guide vane. Background technique [0002] In an engine, such as an aviation turbine engine, an adjustable guide vane device is generally configured to adjust the intake angle of a compressor or a turbine in the engine, so that the engine can work efficiently under different working conditions. In practical applications, the actuator (which can be driven by hydraulic pressure) is generally used to control the rotation of the adjustable guide vane to adjust the intake angle, that is, the transmission mechanism is used to convert the linear displacement of the actuator into the angular displacement of the adjustable guide vane . Generally speaking, the corresponding relationship between the linear displacement of the actuator and the angle of the adjustable gui...

Problems solved by technology

In this method, the displacement target value of the actuator is given on the industrial computer, combined with the position feedback signal of the actuator, and the closed-loop control of the actuator is carried out through the output control signal of the industrial computer. This method can indirectly control the angle of the adjustable guide vane , but the angle of the adjustable guide vane still needs to be read by human eyes, and the reading error affects the calibration accuracy

Therefore, this method may also have problems such as low efficiency and large errors.
