After the position is determined, glue 502 is applied to the front side of the strain gage and then the strain gage is bonded to the experimental test piece at the position determined by the laser line. Accomplish pasting of an experiment test piece, then take one away, put into next test after that, and then realize the quick test in batches, avoided the trouble of nick test one by one, improved the efficiency of work.
(2) Foil gage cutting experiment pasting principle (as figure 6, black foil is foil gage)
The positioning and fixing of the test sample are the same as those of the strain gauge tensile test. Different from the strain gauge stretching experiment, the method for determining the sticking position of the strain gauge is different.
After an experimental sample is fixed, the width of the experimental test piece is measured through scales, corresponding sample piece widths are marked to two sides on a first fixing strip 6 and a second fixing strip 8 by taking a long-edge central point as a center, a laser line of a transverse laser pen 4 penetrates through a diagonal point of a marked point through sliding and rotating, two intersecting lines are formed, two points with the distance between the two points being half of the width of the strain gauge are marked in the left side direction of each marked point, 4 points are marked in total, a laser line of a vertical laser pen 5 penetrates through an opposite angle point of the newly marked point through sliding and rotating, two new intersecting lines are formed, the four lines intersect at four points, two points close to the first fixing strip 6 and the second fixing strip 8 are shearing experimental strain gauge pasting positions, and then the pasting position is determined.
Then coating 502 glue on the front surface of the strain gauge, and bonding the strain gauge on one of the intersection points; then, glue 502 is applied to the front surface of the other strain gage to adhere to the other intersection point. And further realize bonding of foil gage. The subsequent experiments were then completed.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
