[0008] Furthermore, the displacement of the actuator 7 is greater than or equal to the movement displacement of the steering column 2 .

[0009] Furthermore, the actuator 7 is fixed on the support 9 by means of actuator bolts 8 .

[0010] Furthermore, the support 9 is fixed to the ground by support bolts 10 .

[0011] Furthermore, the measuring range of the force sensor 5 is greater than or equal to the maximum force value of the steering column 2 .

[0012] Furthermore, the force sensor 5 includes a cylindrical force sensor and an S-shaped force sensor.

[0013] Beneficial effects:

[0014] By adopting the present invention, the actuator 7 applies an excitation signal, drives the power sensor 5 to move through the binocular plug 6, and the sensor 5 drives the steering column 2 to move through the binocular plug 4. The force sensor 5 feeds back the force signal to the test equipment during the movement. The operator can accurately apply high-frequency sweep and step signals through the control mechanism of the actuator 7, thereby realizing the dynamic and static performance test function of the steering column, improving the stability and consistency of the test data, and improving the test efficiency and quality.
