Description
Technical field
The utility model belongs to aircraft fatigue strength test field, and in particular to a kind of rod piece compression test loading mechanism.
Background technique
In strength test, the compression test of rod structure lesser for length can directly be added on testing machine
It carries, and in, the rod structure of length, load test can not be carried out in testing machine, need to design suitable loading method.
Sometimes the case where load range of testing machine or pressurized strut is less than rod piece breaking load value, Wu Fazhi can also be encountered
Row load test is tapped into, at this time is just needed to design suitable loading method to meet test requirements document.
Utility model content
Purpose of utility model: proposing a kind of rod piece compression test loading mechanism, in meeting, the rod structure of length testing
Machine carries out load test.
Technical solution: the utility model relates to a kind of rod piece compression test loading mechanisms, by loaded strut (1), support side
Case (2), suspension counterweight (4), crossbeam (5), support (6) composition；
Crossbeam (5) keeps horizontal positioned, and one end is connected on load wall by support (6), installation load below the other end
Pressurized strut (3) applies test load, and top is oriented to pulley, equalizer is self-possessed by way of suspension counterweight (4), loaded strut
(1) one end is connected to the middle position of crossbeam, and the other end, which is connected to, to be supported on square chest (2), loaded strut (1) and pressurized strut
(3) axis and horizontal plane, and be located in the plane of symmetry of crossbeam (5).Loading mechanism is as shown in Figure 2 and Figure 3.
As shown in Figure 1, crossbeam is parallel to the horizontal plane, strut and horizontal plane, pressurized strut carry the load schematic diagram of test
Lotus and horizontal plane.
Further, loaded strut (1) is provided with foil gauge, in order to the strain value of measuring rod, while can also lead to
The lower end position of the difference adjustment bar of same section strain value is crossed, it is perpendicular to the ground to reach rod piece.
Further, one end is connect with pressurized strut in crossbeam and is provided with positioning adjusting bolt, it can be real by the rotation of bolt
The adjustment of the existing pressurized strut load line of force, it is vertical with ground to reach the load line of force.
Further, crossbeam connect the type of attachment using ears to three ears with support, to guarantee bonding strength.
Further, loaded strut (1) both ends according to the actual situation, can be with freely-supported or clamped constraint.
By Fig. 1, if pressurized strut load is F, strut internal force N, strut is apart from load wall and the vertical range of pressurized strut point
Not Wei L1, L2 the relationship of loaded value Yu strut load value can be obtained by lever principle:
Advantageous effects: mechanism design is simple, and power transmission is clear, and posting ratio is big, can reduce the use of pressurized strut
Pressurized strut load is changed into tensile load by compressive load, it is easier to apply by load.
Detailed description of the invention
Fig. 1 is the loading mechanism schematic illustration of strut,
Fig. 2 is loading mechanism side view；
Fig. 3 is loading mechanism front view；
Number explanation: the loaded strut of 1-, 2- support square chest, 3- pressurized strut, 4- to hang counterweight, 5- crossbeam, 6- support.
Specific embodiment
Referring to attached drawing 1-3, the utility model relates to a kind of rod piece compression test loading mechanism, by loaded strut (1), support side
Case (2), suspension counterweight (4), crossbeam (5), support (6) composition；Wherein,
Crossbeam (5) keeps horizontal positioned, and one end is connected on load wall by support (6), installation load below the other end
Pressurized strut (3) applies test load, and top is oriented to pulley, equalizer is self-possessed by way of suspension counterweight (4), loaded strut
(1) one end is connected to the middle position of crossbeam, and the other end, which is connected to, to be supported on square chest (2), loaded bar both ends according to the actual situation,
Can be with freely-supported or clamped constraint, the axis and horizontal plane of loaded strut (1) and pressurized strut (3), and it is located at crossbeam
(5) in the plane of symmetry.The structure chart of loading method is as shown in Figure 2 and Figure 3.
As shown in Figure 1, crossbeam is parallel to the horizontal plane, strut and horizontal plane, pressurized strut carry the load schematic diagram of test
Lotus and horizontal plane.
By Fig. 1, if pressurized strut load is F, strut internal force N, strut is apart from load wall and the vertical range of pressurized strut point
Not Wei L1, L2 the relationship of loaded value Yu strut load value can be obtained by lever principle:
For above utility model it is to be understood that under the guiding theory of the utility model, those skilled in the art can
Arbitrarily changed, combined and changed with feature and the feature that do not show clearly herein in the form of to disclosure above
Into belonging to the protection scope of the utility model.Above-mentioned embodiment and example description are exemplaries rather than restricted
's.
