In order to meet the needs of the pre-development test and the post-validation test of the side bar, a set of test devices is needed to detect the manipulating force and corresponding displacement of the side bar.

The aircraft side bar is different from the joystick such as the car shift lever. The maneuvering force of the aircraft side bar and the corresponding displacement test have the following difficulties:

1. The sidebar of the aircraft is double-degree of freedom. It is used to control the pitch and roll axes of the aircraft. In actual operation, coupling is easy to occur. In the design of the sidebar, the maneuvering force and displacement index and the provisions of the airworthiness clause are all proposed in the form of the relationship between the force and the displacement in a single direction, so in the actual test, the single-axis operating force needs to be tested. And corresponding displacement, and strictly avoid the coupling of two degrees of freedom.

The invention designs a manual driving measuring device which is fixed to the base of the device to be tested (ie, the side rod of the aircraft), and simulates the arc movement of single degree of freedom by using two sets of linear guides and ball bearing units. When the linear guide is installed, By installing the adjusting piece, the linear guide is parallel with the S-type tensile pressure sensor to ensure no jamming and excessive friction during driving. The use of linear guides can constrain another degree of freedom, thereby solving the difficulties in the background art.

In addition, a dual-axis tilt sensor is mounted above the side bar clamp unit for acquiring the angle of the pitch axis or the roll axis; an S-type pull pressure sensor is mounted on the right or rear side of the side bar clamp unit for collecting the roll axis or The operating force of the pitch axis. When installing the dual-axis tilt sensor, adjust the sensor to the horizontal level and clear it before the acquisition.
