Abstract

The simple clocking method of fatigue test of a kind of conductive material, connects into hookup by domestic clock, and when hookup is path, domestic clock starts timing；When, after conductive material fatigue fracture in hookup, hookup open circuit, domestic clock stops timing, and now, the time that domestic clock stops is the time that fatigue test is carried out.Domestic clock is connected into hookup timing by the present invention, the auxiliary timing of conductive test material on the middle-size and small-size fatigue machine of laboratory, not only increases timing accuracy, and saves manual time-keeping cost, and simple in construction, maintenance cost is low.

Description

A kind of fatigue test simple clocking method of conductive material

Technical field

The present invention relates to fatigue test technology field, particularly relate to the simple timing side of fatigue test of a kind of conductive material Method.

Background technology

When carrying out tension or the flexing resistance fatigue test of testpieces in the lab, for matching life curve testing experiment part Life-span, need to timing accurate to the life-span of testpieces, large-scale fatigue experimental machine somewhat expensive, and do not possess the small-sized of experimental condition Mechanics Laboratory uses the small-sized fatigue test board of some independent researches, but in process of the test, testpieces rupture time needs Want manual time-keeping, take time and effort.

Summary of the invention

Technical problem solved by the invention is to provide the simple clocking method of fatigue test of a kind of conductive material, to solve The certainly shortcoming in above-mentioned background technology.

Technical problem solved by the invention realizes by the following technical solutions:

The simple clocking method of fatigue test of a kind of conductive material, first connects into hookup, hookup by domestic clock During for path, domestic clock starts timing；When, after conductive material fatigue fracture in hookup, hookup open circuit, during domestic Clock stops timing, and now, the time that domestic clock stops is the time that fatigue test is carried out.

The simple clocking method of fatigue test based on above-mentioned conductive material, the fatigue test simple timing dress of conductive material Put, including domestic clock, wire and conductive clamp, wherein, be in and connect out respectively a wire with the set of cells two ends of clock, and Each wire is respectively welded conductive clamp, then conductive clamp is connected to the two ends composition hookup of testpieces.

In the present invention, conductive clamp includes matrix and two holding pieces being oppositely arranged, and conductive clamp passes through holding piece and examination Test part to connect.

Beneficial effect: domestic clock is connected into hookup timing by the present invention, for the middle-size and small-size fatigue test of laboratory The auxiliary timing of conductive test material on machine, not only increases timing accuracy, and saves manual time-keeping cost, simple in construction, Maintenance cost is low.

Accompanying drawing explanation

Fig. 1 is the structural representation of presently preferred embodiments of the present invention.

Detailed description of the invention

For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below knot Conjunction is specifically illustrating, and the present invention is expanded on further.

See the simple clocking method of fatigue test of a kind of conductive material of Fig. 1, be first in by the set of cells 2 of clock 1 Connecting out a wire respectively in two ends, and is respectively welded conductive clamp in each wire, and conductive clamp is then connected to test The two ends of part 3, in process of the test, hookup is path, domestic clock 1 timing；Conductive material fatigue fracture when testpieces 3 After, hookup open circuit, clock stops, and timing terminates, and now, domestic clock 1 stops at test the most somewhat to be carried out Time because domestic clock 1 can only timing 12 hours, therefore need experimenter to record the time after 12h, save Guard always.

In the present embodiment, conductive clamp includes matrix and two holding pieces being oppositely arranged, conductive clamp by holding piece with Testpieces 3 connects.

In the present embodiment, during this clocking method has been successfully applied to CFRP pultrusion sheet material fatigue test.

The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described.The technology of the industry Personnel, it should be appreciated that the present invention is not restricted to the described embodiments, simply illustrating this described in above-described embodiment and description The principle of invention, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, and these become Change and improvement both falls within scope of the claimed invention.Claimed scope by appending claims and Equivalent defines.
