Abstract
The invention relates to a resistance strain foil with auxiliary coordinates. The resistance strain foil comprises a conventional resistance strain foil, horizontal and vertical 45-degree auxiliary coordinates and horizontal and vertical 60-degree auxiliary pasting coordinates, wherein the horizontal and vertical 45-degree auxiliary coordinates and the horizontal and vertical 60-degree auxiliary pasting coordinates are respectively arranged at the two sides of the conventional resistance strain foil and are used as the reference coordinates of the pasting positions of the resistance strain foil for testing stress and strain. The two sides of the resistance strain foil are respectively provided with the auxiliary coordinates, so the technical problems that the resistance strain foil has a smaller volume, pressurization objects are usually larger than the resistance strain foil during the pasting, the pasting position and direction cannot be accurately ensured because the self pasting coordinates of the resistance strain foil are shielded and the like are solved, and the special difficult problem which is brought by the accurate positioning during the pasting process is solved.
Description
Technical field
The present invention relates to a kind of stress, strain measurement element, especially a kind of resistance strain gage that has auxiliary stickup coordinate.
Background technology
Resistance strain gage is a kind of stress commonly used, strain measurement element; Be exactly as sensing element with resistance strain gage; It is sticked on the measuring point of member securely, because measuring point produces strain, foil gauge also makes the resistance of foil gauge change thereupon being out of shape behind the member stress; Record the resistance variations size of foil gauge again by instrumentation, and convert the strain value of measuring point into.The measuring principle of resistance strain gage is: resistance value wiry is except relevant with the character of material, and is also relevant with length wiry, cross-sectional area.Foil gauge is sticked on the member, and when member stress was out of shape, length wiry and cross-sectional area also changed along with member one, and then resistance variations takes place.
Owing to is to utilize to be out of shape the logarithmic strain of measuring member during resistance strain gage work, and certain directivity is arranged, so the stickup direction of foil gauge is crucial with tested member.Traditional resistance strain gage is it to be pasted coordinate 10 be engraved on the resistance strain gage edge; As shown in Figure 1; Because himself area of resistance strain gage is less; Therefore the pressurization object often is greater than resistance strain gage when pasting, and blocks the stickup coordinate of foil gauge, therefore makes the accurate location in taping process bring great difficulty.
Summary of the invention
The present invention will provide a kind of resistance strain gage that has auxiliary coordinate; It can overcome because himself area of resistance strain gage is less; The pressurization thing often is greater than resistance strain gage when pasting; Original self the stickup coordinate of resistance strain gage is because block and can't accurately guarantee technical matterss such as paste position and direction, and this difficult problem of great difficulty is brought in the accurate location that has solved in taping process.
For realizing above-mentioned purpose, technical scheme of the present invention: a kind of resistance strain gage that has auxiliary coordinate, comprise resistance strain gage commonly used, be characterized in: resistance strain gage two side direction are respectively equipped with level and vertical and 45
0Auxiliary coordinate and level and vertical and 60
0The auxiliary coordinate of pasting, the paste position reference coordinate as resistance strain gage is used for stress, strain testing.
The invention has the beneficial effects as follows: because the resistance strain gage side direction has level and vertical and 45
0Auxiliary coordinate and level and vertical and 60
0The auxiliary coordinate of pasting.When paster, utilize auxiliary-*-coordinate to aim at the good datum line of portrayal in advance on the tested member, and be fixed.In the substrate of resistance strain gage, smear bonding agent and pressurization then and solidify.This function has overcome because himself area of resistance strain gage is less; The pressurization thing often is greater than resistance strain gage when pasting; Original self the stickup coordinate of resistance strain gage is because block and can't accurately guarantee technical matterss such as paste position and direction, and this difficult problem of great difficulty is brought in the accurate location that has solved in taping process.Position that the traditional resistor foil gauge brings and the error on the direction have been got rid of when paster.
Description of drawings
Fig. 1 pastes the existing resistance strain gage floor map that coordinate is engraved on the resistance strain gage edge with it;
Fig. 2 is the floor map of resistance strain gage of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
As shown in Figure 2, the resistance strain gage that has auxiliary coordinate of the present invention is by resistance strain gage 1, level and vertical and 45
0Auxiliary coordinate 2 and level and vertical and 60 of pasting
0The auxiliary coordinate 3 of pasting is formed.Resistance strain gage 1 is used for stress, strain testing, level and vertical and 45
0Auxiliary coordinate 2 and level and vertical and 60 of pasting
0Auxiliary paste position reference coordinate of pasting coordinate 3 as resistance strain gage.Auxiliary paste coordinate when making and original self the coordinate of resistance strain gage be consistent.
Principle of work of the present invention and characteristics:
Having the auxiliary resistance strain gage of pasting coordinate, is a kind ofly except original self the stickup coordinate of resistance strain gage 1, to also have two groups of auxiliary coordinates of pasting in addition in its side direction, and the level that is respectively reaches 45 with vertical
0Coordinate 2 and level and vertical and 60
0Coordinate 3.Auxiliary paste coordinate when making and original self the coordinate of resistance strain gage be consistent.Its effect is: when paster, utilize auxiliary-*-coordinate to aim at the good datum line of portrayal in advance on the tested member, and be fixed.In the substrate of resistance strain gage, smear bonding agent and pressurization then and solidify.Fixed method can be used adhesive tape, glue etc.Because the auxiliary coordinate of pasting is an integral body with resistance strain gage, and be consistent with original self the coordinate of resistance strain gage, therefore the position of resistance strain gage and direction just can accurately meet testing requirement by ten minutes when pasting.This function has overcome because himself area of resistance strain gage is less; The pressurization thing often is greater than resistance strain gage when pasting; Original self the stickup coordinate of resistance strain gage is because block and can't accurately guarantee problems such as paste position and direction, and this difficult problem of great difficulty is brought in the accurate location that has solved in taping process.Position that the traditional resistor foil gauge brings and the error on the direction have been got rid of when paster.And position and the error on the direction brought during paster can be brought bigger influence to measuring accuracy.Especially under the state of two-dimentional strain, it is because position and the error effect on the direction during paster are bigger.No matter this method is on monolithic or right angle sheet or all kinds of strain rosettes if can being applied on the various resistance strain gages.
