Description
Technical field
The present invention relates to rail vehicle technical field, more particularly, to a kind of applied to rail vehicle route impact test
Method.
Background technique
It is by the fixed track set up, by true ultromotivity headstock in existing rail vehicle impact test
Driving acceleration is carried out to test vehicle as driving device, such as test vehicle propulsion is added in test vehicle rear by locomotive engine
Speed gradually raises speed with locomotive, when the test vehicle pre-set velocity needed for reaching impact test pushed, train
Head stops raising speed and braking, and tests vehicle in the case where losing the locomotive motive force state in rear portion, itself slidable travel in orbit,
And then collide with detection device, what detection device can then obtain test vehicle includes dent distortion posture and shock
The related datas such as power.It in this detection process, is driven by true locomotive engine as power source, since locomotive engine needs
Manual operation, operator have hysteresis quality to the operation of train after receiving the information such as speed.Meanwhile locomotive engine itself
Design function is that dragging passenger car or boxcar are normally exercised, therefore locomotive engine accelerates operation, deceleration or braking are
Reaction sensitivity of uniting is low, accelerates sensitive at important time and velocity node not reacting with processes such as brakes, it is difficult to
Of short duration control window phase realizes accurate conversion and control.Pass through the true rail including locomotive engine in the prior art as a result,
Road vehicle is low as the speed accuracy for the rail vehicle impact test that power source is completed, and then can not accurately obtain testing number
According to.
Currently, the impact test of each city rail vehicle, mainly using diesel locomotive as power, traction subject vehicle completion is touched
Hit test.The route impact test of city rail vehicle is onboard manipulated mainly by artificial experience to complete, and due to various reasons may
Lead to test failure, so that passengers inside the car have security risk.Meanwhile the exhaust gas of diesel locomotive discharge is to the person of testing crew
Safety constitutes threat, and there is also greater risks for test process.
In the prior art, mainly have following technical scheme related to the present patent application:

Hit the speed getter of controller, the power car of Control experiment train and operation of breaking off relations between power car unhook controller,
And the driving wheel switch of control power car switching driving.Solves track train impact test success rate in the prior art
It is low, it be easy to cause the technical problem of cost waste etc..
Scheme 2 was Zhong Che Zhuzhou Electric Locomotive Co. Ltd., in application on 09 28th, 2016, and in February 22 in 2017
It is day open, the Chinese invention application of Publication No. CN106441955A " a kind of track train collision test method and system ".It should
It includes: the speed on acceleration orbit that patent application, which discloses a kind of track train collision test method and system, test method,
Maintain the present speed that test train is obtained in section；Judge whether the current vehicle speed of test train meets speed preset condition, such as
Fruit is to maintain current vehicle speed until step 3；If not, test train executes braking；When test train traveling reaches acceleration rail
After unhook section on road, unhook movement is executed, the power car turning in test train is sailed out of；Unpowered vehicle in test train
Into coasting-flight phase, drive towards impact test wall.Being carried out to speed by way of carrying out velocity measuring before executing unhook operation
It is accurate to determine, and bend turning driving is entered by power car, power car is enabled to avoid impact test wall in time, this design enables column
The distance of vehicle unhook positional distance impact test wall is closer, and the distance of corresponding train art skating reduces, and reduces train speed
Degree variation is possible, and speed when train being made to reach collision is more accurate.
Scheme 3 was Zhong Che Zhuzhou Electric Locomotive Co. Ltd., in application on 09 28th, 2016, and December 07 in 2016
It is day open, the Chinese invention application of Publication No. CN106198066A " a kind of track train collision test method and system ".It should
It includes: that the specified region on acceleration orbit is obtained that patent application, which discloses a kind of track train collision test method and system, method,
Take the present speed of test train；Judge whether the current vehicle speed of test train meets speed preset condition, if it is, executing
Unhook movement；It acts if it is not, then test train does not execute unhook and continues to move forward；When test train executes unhook movement
Afterwards, power car enters bend track turn traveling, and unpowered vehicle, which enters, to be slided collision orbit, drives towards impact test wall；Work as test
When train is not carried out unhook movement, power car drives unpowered vehicle to enter bend track turn traveling together.Pass through this use
The mode of bend track turn can increase the distance that test train is controllably run under power car drive, and it is de- to reduce test train
After hook, uncontrollable distance to run slowly reduces collision speed and a possibility that error occurs, enables test result more quasi-
Really.
