Abstract

The invention provides dynamic testing equipment and method for a blade angle measuring sensor. The dynamic testing equipment of the blade angle measuring sensor comprises a base, a rotating disc which is rotationally connected to the base and is used for simulating a propeller hub of a propeller, a driving mechanism arranged on the base and used for driving the rotating disc to rotate, a positioning mechanism arranged on the base and used for mounting the blade angle measuring sensor, driving the blade angle measuring sensor to move in the axial direction of the rotating disc and feeding backa moving distance, an induction disc arranged on the rotating disc and used for being matched with the blade angle measuring sensor for measurement, and a control mechanism used for collecting the moving distance fed back by the positioning mechanism and a voltage value output by the blade angle measuring sensor and acquiring the linearity of the blade angle measuring sensor. The control mechanism is used for carrying out multi-point collection on the moving distance of the blade angle measuring sensor fed back by the positioning mechanism and the voltage value output by the blade angle measuring sensor, and calculating the linearity of the blade angle measuring sensor by taking the moving distance as an input and taking the voltage value as an output.

Description

technical field [0001] The invention relates to the technical field of aero-engine sensor testing, in particular to a dynamic testing device for a blade angle measurement sensor. In addition, the present invention also relates to a dynamic testing method for the blade angle measuring sensor using the dynamic testing equipment for the blade angle measuring sensor. Background technique [0002] With the improvement of engine performance, it is necessary to use the blade angle measurement sensor to accurately measure the change of the blade angle, so as to realize the closed-loop control of the engine speed. For the measurement principle of the blade angle measurement sensor, refer to patent 201510815877.0: the blade angle measurement device mainly includes a cam, a push rod, and a blade angle measurement sensor. When the paddle shaft rotates to change the blade angle, the cam installed on the paddle shaft rotates with the paddle shaft, pushing the ejector rod to move linearly...
