First servo motor and the movement of the second servo motor in component, in the case where zero load, the position of adjustment detection moving slide board,
So that detection device is located at turn around right above workbench；
Second step starts the driving motor of rotary table, drives rotary table rotation；
Third step cooperates test bar with eddy current displacement sensor to detect in rotary table revolution in the case where zero load
Heart offset is directed at angle interference mirror with the laser beam of laser interferometer and is transmitted to angled mirrors to detect rotary table
Rotate angle；Detection workbench is when directly turning platform, with the temperature of thermocouple temperature sensor detection rotary table driving motor
Signal is spent, each signal is uploaded to industrial personal computer, and show by display；
4th step, removes detection moving slide board, and the position of adjustment load moving slide board makes cylinder assembly be located at turn around workbench just
Top adjusts the direction of vertical sleeping conversion loading device；
5th step controls cylinder assembly output pressure, realizes and applies given axially or radially pressure to rotary table；
6th step, when applying axially or radially pressure, the pressure value exported with pressure sensor monitoring cylinder uses laser displacement
Sensor detects the X-direction of rotary table and the deflection of Y direction position；Detection workbench is when directly turning platform, to use
Thermocouple temperature sensor detects the temperature signal of rotary table driving motor, and each signal is uploaded in industrial personal computer, and is led to
Display is crossed to show；
7th step, cylinder assembly stop load, remove load moving slide board, again the position of adjustment detection moving slide board, so that
Detection device is located at turn around right above workbench；
Step 8: after loading is complete, with the centre of gyration of eddy current displacement sensor cooperation test bar detection rotary table
Offset is directed at angle interference mirror with the laser beam of laser interferometer and is transmitted to the rotation of angled mirrors detection rotary table
Gyration, detection workbench are when directly turning platform, with the temperature of thermocouple temperature sensor detection rotary table driving motor
Each signal is uploaded to industrial personal computer, and is shown by display by signal；
9th step, the unloaded experimental data with when load of analysis simultaneously generate assessment report.
