The object of the invention is realized and completed by following technical scheme：
A kind of rail smooth degree on train bogie dynamically adjusts adaptive device, and dynamically adjustment adapts to dress to the rail smooth degree
Put including numerical control telescopic jack；The numerical control telescopic jack is arranged at the single stage suspension spring and axle of the train bogie
Between case.
The top of the numerical control telescopic jack, which is set with a jack overcoat, the outside wall surface of the jack overcoat, to be had
There is the cushion cap of evagination；The single stage suspension spring housing is mounted in the outside of the jack overcoat, and its bottom is supported on described hold
On platform.
The telescopic extensions of the numerical control telescopic jack are 10cm ~ 20cm.
Dynamically adjustment adaptive device also includes a very heavy top control system, the jack control system to the rail smooth degree
System connection controls the flexible of the numerical control telescopic jack.
The control method comprises the following steps：Detect the vertical smooth degree information of track；In train travelling process, thousand
Jin top control system is according to the running status of the train, the installation site of the numerical control telescopic jack and described vertical flat
Compliance information controls the collapsing length and speed of the numerical control telescopic jack, with the height of train bogie described in active accommodation
It is low.
The track vertical smooth-going corresponding on the mileage number where the track checking car is detected using track checking car
Spend information.
It is an advantage of the invention that the numerical control telescopic jack being arranged between single stage suspension spring and axle box can be led
Height that is dynamic, adjusting train bogie in real time so that each wheel can actively adapt to the vertical irregularity of track, so as to have
Effect ground reduces compartment vibration and bogie vibration, is shaken while track vibration and its basis caused by driving conditions can be effectively reduced
It is dynamic, also there is noise reduction with reducing the effect of energy consumption in train journey while vibration damping.

Embodiment
The feature and other correlated characteristics of the present invention are described in further detail by embodiment below in conjunction with accompanying drawing, with
It is easy to the understanding of technical staff of the same trade：
Mark 1-9 is respectively in such as Fig. 1-5, figure：Numerical control telescopic jack 1, very heavy top control system 2, single stage suspension spring 3,
Axle box 4, jack overcoat 5, side frame 6, cushion cap 7, track 8, wheel 9.
Embodiment：As shown in Figure 2,3, the rail smooth degree that the present embodiment is specifically related on a kind of train bogie is dynamically adjusted
Whole adaptive device, it includes numerical control telescopic jack 1 and very heavy top control system 2；Numerical control telescopic jack 1 is arranged on train
Between the single stage suspension spring 3 and axle box 4 of bogie；The control end of the very heavy connection numerical control of top control system 2 telescopic jack 1,
The collapsing length of numerical control telescopic jack 1 can be controlled according to the smooth-going degrees of data of track by very heavy top control system 2；Numerical control
The telescopic extensions of telescopic jack 1 are 10cm to 20cm.
As shown in Figure 2,3, in the present embodiment, the wheel of train is on axle box 4；Numerical control telescopic jack 1 it is upper
Portion is set with the cushion cap 7 in a jack overcoat 5, the outside wall surface of the bottom of jack overcoat 5 with evagination；Single stage suspension spring 3
The outside of jack overcoat 5 and its bottom is sleeved on to be supported on cushion cap 7；The top of single stage suspension spring 3 is connected to train
The bottom of the side frame 6 of bogie；The load of train sequentially passes through two-line suspension spring, bogie, single stage suspension spring 3, axle box 4
And take turns to being transferred to track.
As shown in Figure 2,3, the rail smooth degree in the present embodiment on train bogie dynamically adjusts the control of adaptive device
Method, specifically includes following steps：
1）The smooth degree of track is detected using track checking car, track checking car continuously detects its mileage number and and mileage in detection process
The corresponding vertical smooth degree of number, and mileage number and corresponding vertical smooth degree are stored in database；, can by detection
To obtain the vertical smooth degree of optional position on track.
2）According to the vertical smooth degree of the track gathered, the irregularity state to circuit is estimated analysis.
3）Before train is originated, by the smooth-going data storage of train operation track into very heavy top control system 2.
4）In train travelling process, according to the installation of the position of train and each numerical control telescopic jack 1 ON TRAINS
Position determines the relative position between each numerical control telescopic jack 1 and track, and very heavy top control system 2 is according to each numerical control flexible thousand
Relative position between jin top 1 and track obtains the vertical smooth degree of the track of each lower section of numerical control telescopic jack 1；Jack control
System 2 processed as input parameter, calculates the speed of service of the vertical smooth degree of track and train respectively using control algolithm
The collapsing length of numerical control telescopic jack 1 and stretching speed, and the collapsing length calculated and stretching speed are sent to each numerical control
The control end of telescopic jack 1, numerical control telescopic jack 1 according to the instruction of very heavy top control system 2 actively, adjust it in real time
Collapsing length, and then the height of active accommodation train bogie is to adapt to the vertical irregularity of track.
As shown in Figure 4,5, there is larger depression in track 8；Train in Fig. 4 is fitted without the rail smooth degree of the present embodiment
When train in dynamic adjustment adaptive device, therefore Fig. 4 passes through the recess of track 8, the wheel 9 of train is along the recessed of track 8
Fall into and produce fluctuation, so as to cause train vibration to be jolted；And rail smooth degree of the train in Fig. 5 equipped with the present embodiment is dynamically adjusted
Adaptive device；When train passes through the recess of track 8, numerical control telescopic jack 1 extends downwards, and this allows train automatic
And the irregularity of track 8 is deacclimatized on one's own initiative, it is to avoid the vertical uneven compliance of track 8 causes train vibration to be jolted.
The advantageous effects of the present embodiment are：The numerical control being arranged between single stage suspension spring and axle box is stretched very heavy
Top can adjust the height of train bogie actively, in real time so that each wheel can actively adapt to the vertical injustice of track
It is suitable, so as to effectively reduce wheel-rail interaction, also reduce compartment vibration and bogie vibration, while driving can be effectively reduced
Track vibration and its vibration of foundation caused by process, it is possible to decrease the noise in train travelling process, save energy consumption in train journey.
