Abstract

The invention relates to the technical field of clamping tools, in particular to a fatigue test tool for a high-speed train bogie journal box. The tool comprises a base plate. A first fixing device and a second fixing device which are used for fixing the high-speed train bogie journal box are disposed on the base plate. One end, away from the journal box, of the high-speed train bogie journal box is fixedly connected with the first fixing device through a fixing pin. Protrusions at the bottom on one side of the high-speed train bogie journal box are clamped to the second fixing device. A hydraulic system for fatigue tests penetrates the high-speed train bogie journal box. The fatigue test tool for the high-speed train bogie journal box has the advantages that the high-speed train bogie journal box is clamped by the first fixing device and the second fixing device, testing is performed through the hydraulic system, and during ten million type tests of the whole journal box, each test is completed at one step.

Description

High-speed train bogie axle box fatigue test frock
Technical field
The present invention relates to clamp fixture technical field, especially a kind of high-speed train bogie axle box fatigue test frock.
Background technology
Existing bearing test device is mostly that mode by loaded load intensity and the supporting degree to bearing spindle tested, cannot be to simulating under the different working conditions in actual use procedure, main cause is that axle box need to carry out the high-intensity type approval test (Stromeyer test) of 10,000,000 times, there is no ready-made frock clamp.
Therefore be badly in need of a kind of test unit that is applicable to the experiment of axle box fatigue strength of design, axle box endurance life is carried out to experimental test, ensure the safety and reliability of Vehicle Driving Cycle.
Summary of the invention
The technical problem to be solved in the present invention is: cannot be to the problem of simulating under the different working conditions in actual use procedure in prior art in order to solve, the invention provides a kind of high-speed train bogie axle box fatigue test frock, by the first stationary installation and the second stationary installation, high-speed train bogie axle box is clamped, test by hydraulic system, in 10,000,000 type approval tests of whole axle box, ensure that experimentation once completes.
The technical solution adopted for the present invention to solve the technical problems is: a kind of high-speed train bogie axle box fatigue test frock, comprise: base plate, described base plate is provided with the first stationary installation and the second stationary installation for fixing high-speed train bogie axle box, described high-speed train bogie axle box is fixedly connected with the first stationary installation by fixed pin shaft away from one end of axle box, the projection of the bottom of described high-speed train bogie axle box one side is fastened in the second stationary installation, in described high-speed train bogie axle box, is equipped with the hydraulic system for torture test.
Particularly, between described high-speed train bogie axle box and the second stationary installation, be provided with aluminium pad.
Particularly, described hydraulic system is provided with several for simulating the hydraulic interface of locomotive motion.
The invention has the beneficial effects as follows: a kind of high-speed train bogie axle box fatigue test frock provided by the invention, by the first stationary installation and the second stationary installation, high-speed train bogie axle box is clamped, test by hydraulic system, in 10,000,000 type approval tests of whole axle box, ensure that experimentation once completes.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the front view of high-speed train bogie fatigue test frock of the present invention;

Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present invention is only described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As Fig. 1, shown in Fig. 2, a kind of high-speed train bogie axle box fatigue test frock, comprise base plate 1, base plate 1 is provided with the first stationary installation 3 and the second stationary installation 4 for fixing high-speed train bogie axle box 2, high-speed train bogie axle box 2 is fixedly connected with the first stationary installation 3 by fixed pin shaft 5 away from one end of axle box, the projection 6 of the bottom of high-speed train bogie axle box 2 one sides is fastened in the second stationary installation 4, in high-speed train bogie axle box 2, be equipped with the hydraulic system 7 for torture test, hydraulic system 7 is provided with several for simulating the hydraulic interface 9 of locomotive motion.
In a kind of embodiment, in order to reduce the friction between high-speed train bogie axle box 2 and the second stationary installation 4, between high-speed train bogie axle box 2 and the second stationary installation 4, be provided with aluminium pad 8.
The method of operating of high-speed train bogie axle box fatigue test frock of the present invention is as follows:
After the base plate of this test tool 1 is fixed on test-bed, servo hydraulic machine is connected with servo hydraulic system 7 interfaces in frock, according to the requirement of form test program, apply reciprocating force 10,000,000 times, workpiece can not have Anywhere any fatigue crack.
Taking above-mentioned foundation desirable embodiment of the present invention as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this invention technological thought, carry out various change and amendment completely.The technical scope of this invention is not limited to the content on instructions, must determine its technical scope according to claim scope.
