Problems solved by technology
[0003] For the lifting pedal assembly, the test space is often limited, and the traditional fixture is difficult to clamp around the pedal assembly. If there are too many parts in the test device, it will cause accumulation The error is too large, the test data is inaccurate, and it is easy to damage the surface of other parts when clamping

The invention belongs to the technical field of cockpit testing, and relates to a hoisting type pedal assembly angular displacement testing device and testing method. For a hoisting type pedal assembly, a traditional clamp is difficult to clamp around the pedal assembly, accumulated errors are too large, and the surfaces of other parts are prone to being damaged. According to the angular displacement testing device of the invention, a rotating support, a potentiometer, a coupler and a support are adopted; the potentiometer is installed on the support; the whole rotating support is of a U-shaped structure; an arm body on the inner side of the rotating support is provided with a fork opening structure; the fork opening structure is attached to the outer surface of a lug piece on the outer side of a stand column; an arch-shaped clamp is in clearance fit with a fixing shaft, and is attached onto the inner surface of the lug piece on the outer side of the stand column.The fork opening structure is connected with the arch-shaped clamp in a clamping mode so that the fork opening structure and the arch-shaped clamp can rotate synchronously, and an arm body at the outer side of the rotating support is connected with the potentiometer through the coupler. Accumulated errors caused by too many test transmission links are reduced, the measurement precision requirement is met, and mounting / dismounting is simple.
Description
technical field [0001] The invention belongs to the technical field of cockpit testing, and in particular relates to a testing device and a testing method for angular displacement of a hoisting pedal assembly. Background technique [0002] The pedal assembly has the functions of controlling the rudder of the aircraft and ground turning and braking. The pedal assembly is crucial to the performance and safety of the aircraft, and the force feeling and angular displacement of the pedal assembly also affect the control and comfort of the pilot. In order to measure The rod force / rod displacement curve of the pedal assembly is used to verify whether the function and performance of the yaw control channel meet the requirements. An angular displacement device is needed to measure the rotation angle of the pedal assembly. [0003] For the hoisting pedal assembly, the test space is often limited, and the traditional fixture is difficult to clamp around the pedal assembly. If there are...
