Secondary.
Step 6, rail infrabasal plate 1 is removed from detecting tool, and checks the rail infrabasal plate 1 through the step 5 test
Whether there is damage or deform.
Step 7, if the rail infrabasal plate in the step 6 is not damaged or deformation values are less than or equal to threshold value T, judges inspection
It is qualified to survey；Otherwise judge that detection is unqualified.In the present embodiment, threshold value T takes 0.8 mm, if through the rail infrabasal plate 1 that tests above
Deformation values less than or threshold value 0.8mm, then illustrate that the rail infrabasal plate 1 is qualified, if if that is rail infrabasal plate was tested
More than or equal to 0.8mm, the deformation values of rail infrabasal plate 1 then illustrate that the rail infrabasal plate 1 is unqualified.
The operation principle of the present embodiment is as follows：Use cooperatively to enter rail infrabasal plate 1 using as above testing machine and detecting tool
Row combined load is tested.Wherein, every group of bracing frame 6 be equivalent to track spring, and the simulation rail flange of rail of backing plate 2 in the present embodiment
Combination with the rubber mat plate 2 below the flange of rail.
It is assumed that：Axle weight F1=12.7 tons, convert into F1=124.46 kN, are passed with normal direction at wheel with rail contact point
Pass rail.
Sleeper is concrete sleeper, according to China《Iron nitride films assessment of performance and test for identification specification》（GB
5599-1985）Regulation, to putting on the transverse horizontal force F ' on track using following limit value formula:
F′≤0.85*(15+F/2)=0.85*（15+124.46/2）=65.65 (kN), obtain the level point of limit value load
Power F ' is about 65.65 kN.That is, now, the horizontal component F ' of the limit value load of theoretical upper rail infrabasal plate 1 can not surpass
Cross 65.65kN.
Quantitative measure：The combined load detection of U-type groove face：U-type groove face must not have trauma after combined load test, and which is curved
Bent deflection must not exceed 0.8 mm.
Consider that this test is fastener part simulation test, wheel is to the impact of rail, 1 foozle of rail infrabasal plate, examination
The factor such as experiment device foozle, fastener alignment error and electro-hydraulic servo testing machine loading velocity be slower, so, this
Test experience loading coefficient 1.35.
Therefore, test scale load F=F ' * 1.35=65.65*1.35=88.63 kN, value 90kN.Wherein, experience loading system
Number takes 1.35, and more than coefficient 1, and 90kN is more than 88.63 kN, and such value is in order to the experimental condition that is rigid in checking up, so as to protect
The effectiveness of card rail infrabasal plate test, but the value of test scale load can not be excessively harsh, the rail infrabasal plate 1 for otherwise producing
Would not be qualified.
Rail infrabasal plate 1 is placed on the platform of electro-hydraulic servo testing machine, it is ensured that rail infrabasal plate 1 is relative to testing machine
Pressure head center vertical line is in symmetric condition, and two strut tops of test tool are leaned against the outside in rail infrabasal plate 1U type grooves face respectively
Face, starts descending button, and testing machine is loaded to rail infrabasal plate 1U type grooves face by pressure head with the loading velocity of 1kN/ seconds, works as test
During airborne lotus F=90kN, protect and carry 60 seconds, then unload, be carried out continuously the test 3 times.Hereafter, rail infrabasal plate is removed, is checked for
Damage or deform, when not being damaged or deformation values≤0.8mm, then judge that detection is qualified.
It is rail infrabasal plate U-type groove face combined load test parameterss referring to following table.
Table：Rail infrabasal plate U-type groove face combined load test parameterss
For above-described embodiment, the present embodiment is explained further and issuable change is described as follows：
1st, in above-described embodiment, loading velocity of the testing machine using the 1kN/ seconds, in fact, the loading velocity of testing machine can be with
It is other values in addition to the 1kN/ seconds, is not limited only to the 11kN/ seconds, laboratory technician can adjusts the loading velocity according to demand.
2nd, in above-described embodiment, by detecting that rail infrabasal plate 1 has undeformed and deformation size so as to judging rail infrabasal plate 1
Whether when qualified, threshold value T takes 0.8 mm, and true upper threshold value T in addition to taking 0.8 mm can also take other values, be not limited only to 0.8
Mm, laboratory technician can adjust threshold size according to demand.
3rd, in above-described embodiment, combined load test is carried out 3 times, in fact, the test can also be 2 times, 4 times and 4 times
More than, theoretically test number (TN) is more, more accurate, and in fact, test is also for 1 time feasible, and simply, test there may be for 1 time
Certain error, laboratory technician can Adjustment Tests number of times according to demand.
Above-described embodiment only for technology design of the present utility model and feature are described, its object is to allow and be familiar with technique
