Abstract
The invention provides a testing device capable of coupling a stress field and a chemical field. The testing device comprises an upper bottom plate and a lower bottom plate; the left ends and the right ends of the upper bottom plate and the lower bottom plate are respectively connected with each other by a pull rod; one ends of the pull rods are fixed on the lower bottom plate, and the other ends of the pull rods penetrate through the upper bottom plate and are respectively and fixedly provided with a nut cap; two springs sleeve the parts, between the nut caps and the upper bottom plate, of the pull rods, respectively; test pieces used for testing tolerance are arranged between the upper bottom plate and the lower bottom plate. The testing device is used for testing the tolerance of a product by two damage factors of the stress field and the chemical field, so that the tolerance of the structure of the product can be accurately tested, and work can be better guided according to the test result.
Description
Technical field
The present invention relates to water conservancy, technical field of civil engineering, particularly relate to the test unit that a kind of stress field is coupled with chemical fields.
Background technology
In water conservancy, field of civil engineering, usually need the permanance of test products structure, after knowing the permanance of product structure by test, just can judge its time limit length how applied in the middle of reality and apply.In most cases at present, permanance people for product structure are the durability index recorded according to existing standard in laboratory under single damage factor effect, but, in Practical Project, structure is the corrosion-resistant problem of the double damage factors under bearing load (stress field) with etchant solution (chemical fields) acting in conjunction.Therefore, be necessary to carry out the permanance research of structure under stress field and chemical fields acting in conjunction in laboratory, for this reason, be necessary to have developed the permanance that test unit that a set of stress field is coupled with chemical fields carrys out test products structure.
Summary of the invention
The object of the invention is to solve the defect that above-mentioned prior art exists, a kind of test unit be coupled simultaneously can taking into account stress field and chemical fields double damage factors is provided.
The test unit that stress field is coupled with chemical fields, comprising: upper plate, lower shoe, and the two ends, left and right of described upper plate, lower shoe connect respectively by pull bar; One end of pull bar is fixed on lower shoe, and the other end has block through after upper plate at its end winding support; Pull bar between block and upper plate overlaps respectively and has spring, be placed between upper plate, lower shoe for the experiment test specimen testing tolerance.
Further, the test unit that stress field as above is coupled with chemical fields, described upper plate, lower shoe are made up of steel plate.
Further, the test unit that stress field as above is coupled with chemical fields, described pull bar is circular pull bar.
The test unit that stress field provided by the invention is coupled with chemical fields, by test test specimen is placed between upper plate and lower shoe, then the experimental provision that installation places is placed on etchant solution in a simulating reality and can causes the test carrying out chemical fields in the environment of corrosive attack to product structure, simultaneously because the lower shoe of device and two lateral bracing struts keep maintaining static, tested by the bearing load of spring force to test specimen, tested by the tolerance of these two destructive factors to product, thus more accurately can test out the tolerance of product structure, and then can guiding work better according to the result of test.
Accompanying drawing explanation
Fig. 1 is the test unit structural representation that stress field of the present invention is coupled with chemical fields.
Embodiment
For making the object, technical solutions and advantages of the present invention clearly, below technical scheme in the present invention be clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 1 is the test unit structural representation that stress field of the present invention is coupled with chemical fields, as shown in Figure 1, the test unit that stress field provided by the invention is coupled with chemical fields, comprising: upper plate 12, lower shoe 11, and the two ends, left and right of described upper plate 12, lower shoe 11 connect respectively by pull bar 13; One end of pull bar 13 is fixed on lower shoe 11, and the other end has block 15 through after upper plate 12 at its end winding support; Pull bar 13 between block 15 and upper plate 12 overlaps respectively and has spring 14, the experiment test specimen 16 for testing tolerance is placed between upper plate 12, lower shoe 11.
Principle of work: described spring is high-strength spring, when test test is placed on upper plate, after between lower shoe, then in the middle of the chemical fields being placed on a simulating reality environment, because device lower shoe and two lateral bracing struts keep maintaining static, upper plate can move up and down under the guide effect of pull bar (pull bar is through upper plate setting), the height can testing test specimen can regulate arbitrarily as required, upper plate is pressed on test test specimen by the effect of spring, spring for load application also can be changed according to actual conditions (test test specimen needs the size of stress), and move in company with the freedom of movement of upper plate.This device not only can carry out free adjustment according to the size of test test specimen, simultaneously, by the rigidity of upper plate spring, free adjustment can be carried in load (stress) size tested on test specimen, simultaneously change experimental enviroment according to different chemical fields, just can the tolerance of testing experiment test specimen by the adjustment of these two factors (stress field and chemical fields).
The test unit that stress field provided by the invention is coupled with chemical fields, by test test specimen is placed between upper plate and lower shoe, then the experimental provision that installation places is placed on etchant solution in a simulating reality and can causes the test carrying out chemical fields in the environment of corrosive attack to product structure, simultaneously because the lower shoe of device and two lateral bracing struts keep maintaining static, tested by the bearing load of spring force to test specimen, tested by the tolerance of these two destructive factors to product, thus more accurately can test out the tolerance of product structure, and then can guiding work better according to the result of test.
Further, because different product structures has different bearing loads, in order to adapt to different test test specimens, improve the range of application of apparatus of the present invention, the simultaneously serviceable life in order to improve test unit of the present invention, the test unit that stress field as above is coupled with chemical fields, described upper plate 12, lower shoe 11 are made up of steel plate.
Further, more smooth and easy in order to ensure the process that upper plate is moving up and down along with pull bar, improve experimental test efficiency, described pull bar 13 is circular pull bar.
Last it is noted that above embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
