Unnecessary wheel is caused to change, this can cause evitable maintenance cost.
The commonly known method of vehicle wheel maintenance is so-called drive-by inspection (drive-by inspection), wherein
Check and monitor wheel when vehicle passes by.This is typically inadequate, and can cause mistaken diagnosis, ignore impaired wheel and to useful
Wheel be marked and changed.
A kind of more accurately method is to use so-called Wheel Impact Load Detector (WILD).This detector includes weldering
A series of strain gauges of track are connected to, it quantifies to apply based on the mathematical relationship between the load applied and the deflection of the flange of rail
To the power of track.
Thus the impulsive force measured can be applied to the monitoring structural health conditions of railway wheel.It is presently used for circuit detector
Impact load limit is set as 90000 pounds by Association of American Railroads.
Apply the wheel of this power, i.e., so-called high impact wheel has flat spot (flat generally on their tread
Spot), it is known that flat sliding (slid flat).When wheel while train moves for example because of not loose parking brake and by
During obstruction, it will usually flat sliding occurs.Other damage modes, such as major defect on tread also result in HI high impact car
Wheel.
Although high impact wheel mainly produces the possibility of catastrophic failure because then derailing and attracted attention, they
It is economically also critically important, because HI high impact event makes guide rail that significant strain occur.For example, load feelings compared to non-percussion
Condition, it has been observed that high impact wheel makes the face crack growth rate on track increase by 100 times, and also by increasing crack initiation
And have a negative impact to the health of concrete sleeper.
Unfortunately, it is not easy foundation between wheel damage and failure to contact.Although some high impact wheels can continue
It is on active service for many years without breaking down, but other wheels almost fail immediately.In addition, some patterns of wheel fault, such as broken
Car rim failure and vertical split rim fault is damaged often in the case of far below 90000 pounds impact load limits to occur in wheel
On.
The content of the invention
It is therefore an object of the present invention to provide a kind of method for being used to investigate the Wheel Rail Contact of rail vehicle, it allows
Improve the detection to wheel damage.
The method according to the invention includes：The vertically and/or laterally acceleration of at least one wheel of registration of vehicle；Storage
The acceleration recorded and the related rotation position of wheel；Acceleration event of the identification more than predefined parameter；And for every
Individual identified event, the event is classified using the computational physics model of wheel.
In other words, generally car can be monitored on-line from the acceleration information that the sensor being attached in axle bearing etc. obtains
Wheel health.The acceleration information that what corresponding rotation position was related to the wheel under monitoring recorded allows on wheel circumference
It is determined that the exact position for the defects of being caused by acceleration, also, for being determined and taxonomic defficiency by the physical model of wheel
Type.
This method causes railway operator physically to show them in rolling behavior of the wheel fault one in wheel certainly
Body is just able to detect that these defects, so as to substantially increase the security of operation, and because of the positive detecting event of mistake
The minimum rate of (falsely positive detection event) and reduce maintenance cost.
In a preferred embodiment of the invention, the frequency point of the event associated with the given rotation position of wheel is performed
Analysis, and if under a related rotation position, the frequency of at least one given event exceedes predetermined threshold, then checks car
Wheel.This helps to distinguish the disposable or rare events for example as caused by guide rail defect or foreign object impact and damaged with actual wheel
It is bad, so as to further reduce the possibility that operation wheel is mistakenly classified as to failure.
In another preferred embodiment of the present invention, the vertically and/or laterally acceleration of wheel and the wheel are stored
Related geographical position.Such geocoding acceleration event allows to monitor wheel and guide rail health simultaneously, and identification needs to safeguard
Or the guide rail section checked.In order to obtain geodata, GPS (global positioning system) can be used.
It is further advantageous that according to vertically and laterally acceleration to calculate angular acceleration, and angular acceleration is connected
Stored together with related rotation position and/or geographical position.Which reduce the data set for needing to handle and store.
The acceleration and related rotation position and/or geographical position can be locally stored in the storage of train carrying
In unit.It is then possible to the data are read and analyzed during predetermined maintenance.
Alternatively, the acceleration and related rotation position and/or geographical position can be sent to outside train
The data processing in portion and memory cell.If people are interested in on-line monitoring guideway health, then this be it is particularly advantageous,
Because the acceleration information for giving geographical position can be monitored in the range of entire train in real time, rail state is presented
Always accurate image.
In another preferred embodiment of the present invention, acceleration event is identified by pattern matching algorithm.This allows accurate
Ground determines can be by the extensive defective pattern of Accurate classification.Pattern match also allows to detect unscheduled error pattern, non-predetermined
Error pattern can then be studied.
