To the test screw (5) for installing annular force snesor (4), annular power is installed between test screw (5) and upper connector (14)
Sensor (4), tightening test screw (5) read the value of pretightning force by data collecting instrument；
Step 1.2: rotation load screw rod (13) contacts load screw rod (13) with support (11), makes the axis of first flange disk (7)
Installation site of the line center on upper load-bearing body (3) side plate is located on upper load-bearing body symmetry axis, and rotation load screw rod (13) applies
Load, the size of external applied load is monitored by force snesor (8) and data collecting instrument, and active force is transmitted to by upper load-bearing body (3)
Test screw (5) makes it while bearing axial load and tilting moment, by the way that exciting force is acted on upper carrying using vibration excitor
On the side plate of part (3), pass through ring until some test screw is shut down after loosening or reaching certain vibration number, during this
The changing condition of shape force snesor (4) monitoring test screw pretightning force.
