the clamping assembly 7 comprises a rolling shaft 8, a nut 9 and a clamping groove assembly 5; the card slot assembly 5 comprises a dialing card 11 and a card slot 10 which are integrally arranged; the linear sliding table module 1 comprises a slide way and a sliding block 6 which are connected in a sliding manner, the sliding block 6 is connected with the servo motor 2 through a connecting piece, and the servo motor 2 is used for controlling the sliding block 6 to move in a sliding manner; the card slot 10 and the sliding block 6 are connected through a card dialing 11.

The bottom of the handle 3 is arranged on the handle mounting support 4, the position of the rolling shaft 8 in the clamping groove 10 is adjusted, and the handle is clamped tightly by the locking nut 9, so that handles of different models can be fixed.

The shifting block 11 is arranged on the sliding block 6, the sliding block 6 can drive the shifting block 11 to move, so that the handles 3 are driven to deviate by a given angle, two sets of clamping assemblies 7 can be arranged on one shifting block 11, the angle pressure curves of the two handles can be obtained by one-time movement, the testing space can be saved, and the testing efficiency can be improved;

the computer sends a displacement instruction to the servo driver, and controls the servo motor to drive the sliding block assembly 6 and the shifting card 11 to move linearly, so that the handle is driven to deviate by a given angle. The measured handle moves to the maximum deflection angle at a certain speed from the middle position, then moves to the reverse maximum deflection angle from the angle, and the process is repeated to the set times. The data acquisition card acquires handle output signals, the servo driver feeds back displacement signals, the handle angle is obtained through a conversion formula, the angle and output signal curve of the handle can be obtained, performance parameters are obtained, and the static performance and the dynamic performance of the handle are further analyzed.
