Abstract

The invention provides a connection rod tensile compression simulating fatigue test bench. The connection rod tensile compression simulating fatigue test bench is characterized by comprising a test bench framework (1), a hydraulic pressure loading system (2), a fixing clamp (3) and a connection rod test piece (4); the hydraulic pressure loading system (2) and the fixing clamp (3) are mounted on the test bench framework (1); and the connection rod test piece (4) is mounted on the fixing clamp (3). The connection rod tensile compression simulating fatigue test bench is capable of carrying out a test within a short cycle with high efficiency, strengthening the fatigue test and detecting the fatigue characteristic of the connection rod more comprehensively.

Description

Connecting rod tension and compression simulation fatigue test board
Technical field
The present invention relates to a kind of block testing stand, relate in particular to a kind of connecting rod tension and compression simulation fatigue test board.
Background technology
Connecting rod is the core component of stroke piston combustion engine, is also one of critical piece bearing in internal combustion engine larger alternate load, and its reliability directly affects the safety of internal combustion engine operation.The Main Means of carrying out at present connecting rod fatigue reliability Journal of Sex Research comprises simulation calculation, real machine test and simulation torture test.Simulation calculation is convenient, fast, cost is low, a lot of for the simulation calculation of connecting rod, but can only carry out to fatigue reliability analysis and the checking of tendency, and boundary condition is uncertain; Real machine test can reflect the real working condition of connecting rod, but the test period is long, cost is higher, and can not carry out strenuous test; Simulation torture test can be higher with the shorter cycle efficiency test, and can strengthen torture test, more fully check the fatigue properties of connecting rod
At present, the domestic connecting rod tension and compression simulation fatigue test board that not yet has independent research.Therefore, development engine link tension and compression simulation fatigue test board has larger meaning.
Connecting rod is one of critical component of engine, and its reliability has vital effect to machine life.In order to study the fatigue properties of engine link under Tensile or Compressive Loading, the load mode of the engine link testing table servo apply hydraulic pressure of developing carries out tension and compression loading to connecting rod.
summary of the invention
Technical matters to be solved by this invention is to provide a kind of efficiency that can be higher with the shorter cycle and tests, and can strengthen torture test, more fully checks the connecting rod tension and compression simulation fatigue test board of the fatigue properties of connecting rod.
In order to solve the problem of tradition existence, to the invention provides following technical scheme be:
A kind of connecting rod tension and compression simulation fatigue test board, it is characterized in that, described connecting rod tension and compression simulation fatigue test board, comprise test bed framework, hydraulic loading system, stationary fixture, connecting rod test specimen, hydraulic loading system and stationary fixture are installed in described test bed framework, connecting rod test specimen is installed on described stationary fixture.
Further, described test bed framework adopts four root posts and eight cross bars to form.
Further, described hydraulic loading system is made up of hydraulic cylinder, accumulator, surplus valve, oil filter, hydraulic power unit, motor, fuel tank, retaining valve, servo electromagnetic valve, hydraulic amplifier.
The beneficial effect that the present invention brings is:
The present invention has that equipment is small and exquisite, precise control, measuring accuracy are high, test specimen convenient mounting and clamping, simple operation and other advantages.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Number in the figure is:
1-test bed framework, 2-hydraulic loading system
3-stationary fixture, 4-connecting rod test specimen.
Embodiment
Below to by reference to the accompanying drawings preferred embodiment of the present invention being elaborated, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
As shown in Figure 1, a kind of connecting rod tension and compression simulation fatigue test board, described connecting rod tension and compression simulation fatigue test board, comprise test bed framework 1, hydraulic loading system 2, stationary fixture 3, connecting rod test specimen 4, hydraulic loading system 2 and stationary fixture 3 are installed in described test bed framework 1, on described stationary fixture 4, connecting rod test specimen 4 is installed, described test bed framework 1 adopts four root posts and eight cross bars to form, described hydraulic loading system 2 is by hydraulic cylinder, accumulator, surplus valve, oil filter, hydraulic power unit, motor, fuel tank, retaining valve, servo electromagnetic valve, hydraulic amplifier composition.
In sum, the present invention has that equipment is small and exquisite, precise control, measuring accuracy are high, test specimen convenient mounting and clamping, simple operation and other advantages.
The above; it is only one of the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; the variation that can expect without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
