Abstract
It needs to carry out longitudinal and lateral bidirectional couple in the test of pressure vessel Crack Fatigue to reinforce, under actual working environment, some parts not only in longitudinal stress, laterally also can stress, traditional fatigue tester is difficult be laterally applied to pressure simultaneously in the case where longitudinal stretching or compression.Present invention mainly solves the problem of be realized in such a way that longitudinal one direction reinforces and meanwhile to test specimen vertical and horizontal reinforce the case where.Hydraulic servo pump station longitudinally reinforces fixture, pedestal is set longitudinally to generate relative motion trend, oblique arm is driven, so that slide bar is generated movement tendency on transverse arm, acts on test specimen to apply transverse pressure, it is successfully realized and is transformed into two-way reinforcing by unidirectionally reinforcing, the invention simplifies experimental facilities, has saved cost, and reinforcing laterally and longitudinally is linked up, keep experimentation more rational, test result is made to have more referential.
Description
Technical field
The present invention is suitable for general digital standard fatigue tester, is stretched and is compressed in particular for test specimen
Test.
Background technique
It is reinforced as shown in fig. 7, needing to carry out longitudinal and lateral bidirectional couple in the test of pressure vessel Crack Fatigue, in reality
Under the working environment of border, some parts not only in longitudinal stress, laterally also can stress, traditional fatigue tester is difficult in longitudinal drawing
Pressure is being laterally applied to simultaneously in the case where stretching or compressing.Because a kind of longitudinal direction of the invention and cornering fatigue test device are for protecting
The reliability for demonstrate,proving fatigue test results is significant.It is illustrated in figure 8 force analysis when mechanism operation, wherein。
Summary of the invention
Present invention mainly solves the problem of be realized in such a way that longitudinal one direction reinforces and meanwhile to test specimen it is longitudinal and horizontal
To the case where reinforcing.Hydraulic servo pump station longitudinally reinforces fixture, and pedestal is made longitudinally to generate relative motion trend, drives oblique
Arm makes slide bar generate movement tendency on transverse arm, acts on test specimen to apply transverse pressure, is successfully realized and is turned by unidirectionally reinforcing
Become two-way reinforcing, the invention simplifies experimental facilities, has saved cost, and reinforcing laterally and longitudinally is linked up, is made
Experimentation is more rational, and test result is made to have more referential.
The present invention mainly includes pedestal, oblique arm, slide bar, transverse arm and fixture.
Pedestal: pedestal is connected and fixes with fixture, and pedestal right end is smoothly connected with oblique arm lower end, and oblique arm can be around pedestal or so
Freely overturn.
Oblique arm: oblique arm lower end is smoothly connected with pedestal, can freely be overturn around pedestal or so, and upper end and slide bar smooth end connect
It connects, also can freely relatively rotate.
Slide bar: slide bar left end devises the biggish spring of elasticity modulus, is come into full contact with by a gasket with test specimen,
Right end is smoothly connected with oblique arm, and the smooth sliding slot being placed in transverse arm, slide bar can move left and right between sliding slot.
Transverse arm: beam position can be adjusted above and below testing machine to be directed at test specimen, and transverse arm right end is provided with sliding slot, groove face it is horizontal and
Smooth, slide bar can freely horizontally slip on the chute.
Fixture: fixture upper end is fixed, and lower end can adjust position up and down to clamp the test specimen of different length, while hydraulic servo
Pumping plant is by realizing the stretching and compression to test specimen to the effect of fixture lower end applied force.

Specific embodiment
It is as shown in Figure 1 a kind of two-way reinforcing fatigue experimental device, including pedestal, oblique arm, slide bar, transverse arm, fixture.It is described
Pedestal is connect with oblique arm lower end by an iron prop body, and is fixed with two screws, and oblique arm can be freely rotated around iron prop or so.Tiltedly
An iron prop is equally interted in arm upper end, and oblique arm can be freely rotated around column or so, and iron prop is placed in the horizontal concrete chute of transverse arm right end, sliding
Bar right end is nested with iron prop, is screwed, and slide bar left end can firmly clamp test specimen.Iron prop can be along cunning under oblique arm active force
Slot horizontally slips, and the spring on the left of slide bar is compressed or stretched, to apply lateral pressure or pulling force to test specimen.This knot
Structure can be applied to general fatigue criterion testing machine, be laterally applied to press to test specimen while realization to be longitudinally applied to pulling force or pressure
Power or pulling force.
