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
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.
