Central alignment pedestal 45 in setting with can be connect with 8 plane tangent of thin-wall curved-surface part, adapt to 8 surface shape of thin-wall curved-surface part
Shape, thin-wall curved-surface part 8 are in undeformed state before tested, but due on 8 surface of thin-wall curved-surface part each point with
Difference in height between displacement sensor 3 is inconsistent, therefore the length of 3 telescopic rod of each displacement sensor is inconsistent, the upper computer software
It can record the current location of each 3 telescopic rod of displacement sensor, and this position as zero displacement point, that is, it is unchanged to record part
Then the state of shape carries out assembling test to thin-wall curved-surface part 8, 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 8 surface of part, due to the design of flexural pivot 43, so that thin-walled
When angular deflection occurs, central alignment pedestal 45 with thin-wall curved-surface part 8 can deflect while numerical value occurs curved surface part 8
Normal Displacement, thus will not damage can only the flexible displacement sensor 3 of vertical direction, and can actual response thin-wall curved-surface part 8
Vertical direction shift value caused by surface displacement monitoring point, the direction of measured displacement it is single and it is known that measured displacement number
Value is accurate, according to actual needs by upper computer software, records 3 telescopic rod current location of displacement sensor again, then passes through
Upper computer software, which is read, calculates the distance between telescopic rod difference twice, fills at monitoring point for displacement as on thin-wall curved-surface part 8
Vertical direction shift value when with after test compared with original state.
