Description
Technical field
The present invention relates to a kind of devices and methods therefor carrying out separately static strength and torture test for pivoted arm axle box, belong to technical field of rail traffic.
Background technology
Along with the universal rapidly of domestic city track traffic and the significantly lifting of Vehicle Speed, the bogie frame for bearing body and transmitting tractive power proposes higher design and use requirement.Current domestic track traffic adopt the primary spring of bogie, adopt axle-box locating mode at large, i.e. axle box swivel arm location structure form, is normally defined pivoted arm axle box.
As the earlier application patent of open following content, application number is 201020542266.6, name be called that rail vehicle one is elastic positioning device, its be arranged on bogie frame and axletree vertical between, include pivoted arm axle box and be arranged at the primary spring device on axle box top.One end of axle box is by caoutchouc elasticity node installation in framework, and its other end is connected with framework by a vertical damper.
Pivoted arm axle box stress is comparatively complicated in actual use, current design all belongs to imitation, Analogy, and not having static strength and torture test standard, domestic each rail vehicle manufacturer did not also carry out static strength and the torture test of pivoted arm axle box specially.
After completing the analysis to axle box stress based on existing pivoted arm axle box device for measuring force, by carrying out mathematical statistics to test figure, combined circuit dynamic test result can obtain the data that some are more close to virtual condition, again these data carried out arranging and be converted into equivalent load or equivalent load, follow-uply can be applied on pivoted arm axle box to set up the basis of test of static strength and torture test.
Current domestic application pivoted arm axle box test is connected to by axle box on the framework of original bogie, while carrying out static strength and torture test to bogie frame, takes into account the intensity and life-span of investigating axle box.Mainly there are following shortcomings and deficiencies:
1, axle box is connected on framework, with framework and tests simultaneously, the practice state of axle box can not be simulated, because the test of static strength of bogie and fatigue test method can only be applicable to framework, and be not suitable for axle box.
When 2, parts being carried out to the test examination of fatigue strength, circuit can not be adopted completely to compose, and (circuit spectrum is that rail vehicle is in operational process, regulation circuit is measured the strain of predetermined portion on car, acceleration, displacement, frequency, the isoparametric summation of vibration) load, but should circuit compose existing load reasonably decompose, equivalence, getting its equivalent value reloads on parts, otherwise can axle box can not produce fatigure failure forever because imposed load is too little, thus also do not go out correct conclusion.
When 3, carrying out axle box torture test on existing testing table or circuit, all do not consider the impact of vibration damper on axle box, have ignored the effect of vibration damper, axle box experimental data meeting distortion is more.
In view of this, special proposition present patent application.
Summary of the invention
Pivoted arm axle box static strength of the present invention and fatigue experimental device and method thereof, its object is to solve above-mentioned prior art Problems existing and the equivalent load that converses with reference to circuit spectrum loading, static strength and torture test is implemented separately for pivoted arm axle box, with the test specification of this multiple directions load of standardizing and flow process, to obtaining axle box intensity and fatigue test results really and accurately, auxiliary structure and the stress design improving and optimize axle box.
Another goal of the invention is, reflects the stress influence that pivoted arm axle box is subject to all sidedly, records and the stress data of quantized key point, for whether rationally providing foundation by data analysis and research to determine that axle box designs.
For achieving the above object, described pivoted arm axle box static strength and fatigue test method as follows:
Adopt the test unit including and load crossbeam and axle box seating, pivoted arm axle box is installed on axle box seating;
At the vertical start cylinder of journal box spring seat place's connection first of pivoted arm axle box, connect the second vertical start cylinder, horizontal start cylinder and longitudinal start cylinder respectively at the elastic panel nodes place of pivoted arm axle box;
Apply above-mentioned 4 start cylinders simultaneously and vertical, horizontal and vertical load is applied to pivoted arm axle box, to complete the cycle operation needed for torture test;
Implement test of static strength time, individually or the above-mentioned start cylinder of Combination application to pivoted arm axle box imposed load, to obtain the stress data of region of interest.
As above-mentioned basic scheme, be different from prior art and cannot implement axle box static strength or torture test individually, the present invention is based on the main connecting portion of test unit to pivoted arm axle box and implement directed load, stress data can be obtained individually in fatigue and test of static strength, thus axle box force-bearing situation and life appraisal can be carried out more exactly, for axle box optimal design provides science reliable Data support.
For improving the acquisition of integration test and key point stress data when test of static strength, stress induction sheet can be pasted in the region of interest of pivoted arm axle box, utilize static tester record stress data.After test of static strength terminates, by counter stress data analysis and research, can determine that whether the design of structure of axle box is reasonable.
For increasing vibration damper side when torture test to the test of axle box entire effect, at the damper base place of pivoted arm axle box, vibration damper or start cylinder can be loaded with.
For improving the integration test ability of vertical for elastic panel nodes place, horizontal and longitudinal loading, improve test data accuracy, one node can be installed at the elastic panel nodes place of pivoted arm axle box and load seat, second vertical start cylinder, horizontal start cylinder and longitudinal start cylinder are connected to node and load seat, thus by elastic panel nodes place be subject to the load in three directions, load seat by node and connect.
For improving the accuracy that start cylinder transmits at imposed load direction upper stress, resiliency supported can be connected with in the bottom of horizontal start cylinder and longitudinal start cylinder.
Based on above-mentioned design concept, and apply above pivoted arm axle box static strength and fatigue test method and following test unit can be realized:
Static strength and fatigue experimental device mainly include and load crossbeam and axle box seating, wherein, the axle box of pivoted arm axle box is fixed on axle box seating, the journal box spring seat at its top connects the first vertical start cylinder, connects the second vertical start cylinder, horizontal start cylinder and longitudinal start cylinder at its elastic panel nodes place respectively.
