State, due to that can deflect certain angle using ball pivot 43, i.e. central alignment base 45 in curved surface joint device, therefore curved surface connection is filled
Central alignment base 45 in putting with can be connected with the plane tangent of thin-wall curved-surface part 8, adapt to the surface shape of thin-wall curved-surface part 8
Shape, thin-wall curved-surface part 8 before tested, in undeformed state, but due on the surface of thin-wall curved-surface part 8 each point with
Difference in height between displacement transducer 3 is inconsistent, therefore the length of the expansion link of each displacement transducer 3 is inconsistent, the upper computer software
The current location of each expansion link of displacement transducer 3 is can record, and part is recorded unchanged in this position as zero displacement point
The state of shape, then carries out assembling test to thin-wall curved-surface part 8, and thin-wall curved-surface part 8 will deform, thin-wall curved-surface zero
Each monitoring point for displacement will change relative to original state on the surface of part 8, due to the design of ball pivot 43 so that thin-walled
When there is angular deflection, central alignment base 45 can enter horizontal deflection while there is numerical value to curved surface part 8 with thin-wall curved-surface part 8
Normal Displacement, thus will not damage can only the flexible displacement transducer 3 of vertical direction, and can actual response thin-wall curved-surface part 8
Vertical direction shift value produced by surface displacement monitoring point, the direction of measured displacement is single and, it is known that the number of measured displacement
Value is accurate, the expansion link current location of displacement transducer 3 is recorded again by upper computer software according to actual needs, then passes through
Upper computer software reads and calculates the distance between expansion link difference twice, is filled as at the top offset monitoring point of thin-wall curved-surface part 8
Vertical direction shift value during with after experiment compared with original state.
