Train operation influences information, that is, calculates separately the associated rate of wheel load reduction of wheel rail force, derailment coefficients and impact equivalent, take turns to cross
The associated unstability amplitude of shifting amount, frequency and wheel to the angle of attack, and by train operation influence information in each information respectively with accordingly set
Determine range to be compared, judges that train operation influences each information in information and determines with the presence or absence of abnormal conditions according to calculated result
In the case where the Information abnormity of rate of wheel load reduction, the extremely corresponding failure of rate of wheel load reduction is determined further according to mapping relations database
Type is that wheel flat and steel spring are broken, and further determines that train fault type is that wheel flat or steel spring are broken.Specifically
Ground, by rail vibration information come auxiliary judgment, wherein wheel flat vibration frequency and wheel pair turn frequent related, and generally 1
Times or integral multiple relationship, however steel spring fracture after caused rail vibration frequency be it is uncertain, according to rail vibration frequency
Rate can determine whether out turn frequent identical (1 times relationship) of the rail vibration frequency with wheel pair, hence, it can be determined that the fault type of train
It is wheel flat.
Fig. 7 is that the structure of railway goods train bogie hanging element abort situation identifying system provided in an embodiment of the present invention is shown

Cross force and vertical force, wheel to displacement and are taken turns to the angle of attack and rail vibration, and acquisition rail side safety detection device detects dynamic
The corresponding testing result of mechanical characteristic, i.e. acquisition wheel-rail lateral force and vertical force, wheel to displacement and are taken turns to the angle of attack and rail vibration
It is dynamic.Then from three safety, stability and vibration characteristics angles, with bogie suspension element fault state and dynamic performance
Mapping relations carry out check analysis, the position of type and failure to failure carries out judgement identification, if test obtains
Result corresponding fault type can not be found in mapping relations database, then bogie suspension element otherwise do not occur therefore
Hinder or is that the failure does not generate more apparent influence to the dynamic performance of vehicle；If failure is reflected with dynamic performance
Fault type corresponding with test result can be found by penetrating in the database of relationship, then the source of trouble and failure can be realized
The identification judgement of bogie suspension element fault is realized in the accurate positioning of position.Specifically, kinetic characteristics testing result is defeated
Out into the mapping relations database prestored.The structure that Fig. 6 shows mapping relations database provided in an embodiment of the present invention is shown
It is intended to, as shown in fig. 6, can test to obtain wheel rail force (cross force and vertical force), wheel track cross by rail side safety detection device
Shifting amount (wheel is to displacement and takes turns to the angle of attack) and rail vibration characteristic, the failure of every kind of bogie suspension element all correspond to multiple dynamic
The variation of mechanical performance index.For the malfunction identification of bogie steel spring fracture, the obvious change of wheel impacts equivalent
Change indicate bogie system there are wheel flat, wheel out of round or steel spring fracture etc. failures, rate of wheel load reduction it is obvious
Variation indicates that there are the failures such as wheel flat or steel spring fracture, from the point of view of the two indexs, wheel flat and steel spring fracture
Reflected dynamic performance be it is similar, judged by rail vibration auxiliary, wheel flat vibration frequency and wheel pair
It is closely related to turn frequency, usually 1 times or at integral multiple, rail vibration frequency caused by steel spring is broken be it is uncertain, because
This, can carry out auxiliary judgment identification to malfunction by rail vibration.
The determination of abort situation is carried out through the above way, and steps are as follows:
Acquisition device obtains the wheel rail force (cross force and vertical force) of rail side safety detection device detection, the traversing amount of wheel track
(wheel is to displacement and takes turns to the angle of attack) and rail vibration characteristic, the kinetic characteristics that transmitting device gets acquisition device are examined
Result is surveyed to export to the mapping relations database prestored.Processing unit is according to kinetic characteristics testing result in the mapping relations
Corresponding train operation is associated in database influences information, is influenced according to the corresponding train operation of kinetic characteristics testing result
Information determine train whether failure.Specifically, processing unit calculates wheel rail force (cross force and vertical force), the traversing amount of wheel track
(wheel is on displacement and takes turns on the angle of attack) corresponding train operation influences information, as shown in fig. 6, the corresponding column of the variation of wheel rail force
Vehicle influence on system operation information is rate of wheel load reduction, derailment coefficients and impact equivalent, the corresponding train of variation of the traversing amount that moves in turn
Influence on system operation information is unstability amplitude, frequency and wheel to the angle of attack.Processing unit is closed according to kinetic characteristics testing result in mapping
It is to be associated with corresponding train operation in database to influence information, according to the corresponding train operation shadow of kinetic characteristics testing result
It rings information and determines train fault position according to train operation influence information is calculated.It is taken turns for example, processing unit calculates separately out
Rail power and wheel on the corresponding train operation of traversing amount influence information, that is, calculate separately the associated rate of wheel load reduction of wheel rail force,
Derailment coefficients and impact equivalent, wheel influence the associated unstability amplitude of traversing amount, frequency and wheel to the angle of attack, and by train operation
Each information is compared with corresponding setting range respectively in information, judges that each information is with the presence or absence of different in train operation influence information
Reason condition in the case where the Information abnormity for determining rate of wheel load reduction according to calculated result, is determined further according to mapping relations database
The extremely corresponding fault type of rate of wheel load reduction is that wheel flat and steel spring are broken, and further determines that train fault type is vehicle
Take turns flat scar or steel spring fracture.Specifically, by rail vibration information come auxiliary judgment, wherein wheel flat vibration frequency and wheel
Pair turn frequent correlation, the relationship of generally 1 times or integral multiple, however caused rail vibration frequency is not after steel spring fracture
Determining, turn frequent identical (1 times relationship) of the rail vibration frequency with wheel pair be can determine whether out according to rail vibration frequency, therefore,
The fault type that can determine train is wheel flat.
