A static strength and fatigue test is implemented independently for the tumbler type shaft housing by taking an equivalent load converted from a line spectrum load, so that the test specifications and flows of loads in a plurality of directions are standardized to obtain a real and accurate shaft housing strength and fatigue test results and further assist in the improvement and optimization of the structure and stress design of the shaft housing. The test device for a static strength and fatigue test method of the tumbler type shaft housing comprises a loading beam and a shaft housing seat. A shaft housing body of the tumbler type shaft housing is fixed on the shaft housing seat. A shaft housing spring seat on the top of the tumbler type shaft housing is connected with a first vertical actuating cylinder. A second vertical actuating cylinder, a transverse actuating cylinder and a longitudinal actuating cylinder are connected to an elastic joint of the tumbler type shaft housing respectively.
Description
Technical field
The utility model relates to a kind of device that carries out static strength and torture test to the pivoted arm axle box separately, belongs to the track traffic technical field.
Background technology
Along with the domestic city track traffic popularize rapidly the significantly lifting with Vehicle Speed, for the bogie frame of bearing body and transmitting tractive power higher design and use requirement has been proposed.The single stage suspension system of bogie that present domestic track traffic is adopted adopts the axle box locator meams at large, and promptly axle box pivoted arm location structure form is normally defined the pivoted arm axle box.
As formerly applying for a patent of following content disclosed; Application number is 201020542266.6; To be called rail vehicle one be elastic positioning device to name, its be arranged on bogie frame and axletree vertical between, including the pivoted arm axle box and being arranged at one of axle box top is spring assembly.One end of axle box is installed on framework through the caoutchouc elasticity node, and its other end is connected with framework through a vertical damper.
Pivoted arm axle box stress is comparatively complicated in actual use; Current design all belongs to imitation, analogy design; And static strength and torture test standard are not arranged, domestic each rail vehicle manufacturer had not carried out the static strength and the torture test of pivoted arm axle box specially yet.
After the analysis of existing pivoted arm axle box device for measuring force completion to the axle box stress; Through test figure is carried out mathematical statistics; Combined circuit dynamic test result can obtain the data that some more are close to virtual condition; Put and be converted into these data in order equivalent load or equivalent load again, follow-up can being applied on the pivoted arm axle box to set up the basis of test of static strength and torture test.
Domestic application pivoted arm axle box test at present is that axle box is connected on the framework of original bogie, when bogie frame is carried out static strength and torture test, takes into account intensity and the life-span of investigating axle box.Mainly there are following shortcomings and deficiencies:
1, axle box is connected on the framework, makes an experiment simultaneously with framework, can not simulate the practice state of axle box,, and be not suitable for axle box because the test of static strength of bogie and fatigue test method can only be applicable to framework.
When 2, parts being carried out the test examination of fatigue strength; (the circuit spectrum is that rail vehicle is in operational process can not to adopt the circuit spectrum fully; The isoparametric summation of strain, acceleration, displacement, frequency, vibration at regulation position on measurement car on the regulation circuit) load; Existing load is reasonably decomposed, equivalence but should compose circuit; Get its equivalent value and reload on the parts, otherwise can or not produce fatigure failure forever because of the too little axle box of imposed load, thus also do not go out correct conclusion.
When 3, on existing testing table or circuit, carrying out the axle box torture test, all do not consider the influence of vibration damper to axle box, ignored the effect of vibration damper, axle box experimental data meeting distortion is more.
In view of this, the special present patent application that proposes.
The utility model content
The utility model described pivoted arm axle box static strength and fatigue experimental device; Its purpose is to solve problem that above-mentioned prior art exists and the equivalent load that converses with reference to the circuit spectrum loading; Implement static strength and torture test to the pivoted arm axle box separately; With the test specification and the flow process of these a plurality of direction load of standardizing, in the hope of obtaining axle box intensity and fatigue test results really and accurately, the auxiliary raising and structure and the stress design of optimizing axle box.
Another purpose of design is, reflects the stress influence that the pivoted arm axle box receives all sidedly, and whether the stress data of record and quantized key point is for rationally providing foundation through data analysis and research with definite axle box design.
For realizing above-mentioned purpose of design, described pivoted arm axle box static strength and fatigue experimental device mainly include:
Load crossbeam and axle box seating, wherein, the axle box of pivoted arm axle box is fixed in axle box seating, and the journal box spring seat at its top connects the first vertical cylinder, connects the second vertical cylinder, horizontal cylinder and vertical cylinder respectively at its elastic panel nodes place.
Innovative approach is particularly, and the damper base place of pivoted arm axle box is loaded with vibration damper or cylinder.
One node is installed at the elastic panel nodes place of pivoted arm axle box is loaded seat, the second vertical cylinder, horizontal cylinder and vertical cylinder are connected to node and load seat.
In laterally cylinder and the vertically bottom of cylinder, be connected with resiliency supported respectively.
Content to sum up, the utility model pivoted arm axle box static strength and fatigue experimental device have the following advantages:
1, implements static strength and torture test to axle box individually, can realize the standardization of test specification and flow process, can obtain intensity and fatigue data really and accurately, help to improve the rationality of axle box structure and stress design.
2, can obtain the stress data of axle box integral body and key point all sidedly, for definite axle box design whether foundation being provided rationally through data analysis and research.
