Abstract

The present invention provides a dynamic testing device and method for a blade angle measuring sensor. The dynamic testing device for a blade angle measuring sensor includes a base, a turntable that is rotatably connected to the base and used to simulate a propeller hub, and is arranged on the base and is used to drive the turntable. The rotating drive mechanism is set on the base for installing the blade angle measurement sensor and the positioning mechanism for driving the blade angle measurement sensor to move along the axial direction of the turntable and feeding back the moving distance. Cooperate with the induction plate for measurement and the control mechanism for collecting the moving distance fed back by the positioning mechanism and the voltage value output by the blade angle measurement sensor and obtaining the linearity of the blade angle measurement sensor. The control mechanism collects 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 through multi-point acquisition, and calculates the linearity of the blade angle measuring sensor with the moving distance as input and the voltage value as 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...
