The test platform structure principle is introduced
This multi-function test stand has six independently moving cell A, and each unit can be finished the function that horizontally rotates, laterally moves and make locomotive incline and put respectively.Each unit comprises 4 layers of platform altogether, and topmost one deck is plane rotatable platform P
1, the surface level inner curve of finishing locomotive rotates simulation; The second layer be make locomotive incline the pendulum platform (abbreviation inclines and balances platform P
2), finish the circuit superelevation simulation of locomotive; The 3rd layer is the mount pad of the gear train of screw mandrel-nut, drives the mobile platform P that second layer platform inclines and puts
3, the 4th layer of platform P
4Finish top three platforms and laterally move, the horizontal of finishing in the test of curve bend of bogie moves.
When testing, at first wheelbase, the gauge according to tested locomotive, vehicle carries out the adjustment of testing table, and the adjustment of gauge relies on and moves the plane rotatable platform P of the superiors along T type guide groove 19 directions
1Above load sensor 2 realize, the adjustment of wheelbase rely on adjust each independently the distance between the moving cell finish.
After the multi-function test stand adjustment finished, locomotive, vehicle were by getting on the bus crane span structure or winch on the testing table with overhead traveling crane.And at two ends hitch stationkeeping locomotive or vehicle.
During test, control system is controlled each drive part of each moving cell A, by the order that weaves in advance rotate, incline pendulum, translation etc., simulates locomotive, right laterally the moving of curve, superelevation and the wheel of vehicle by the curve bend time respectively.(simulation locomotive since the first round to transit to the adjustment curve section by straight-line segment, the adjustment curve section is arranged to segment of curve again, simulates through the curve bend of the overall process of straight-line segment to a last wheel via the adjustment curve section at last) simultaneously can be in the process of motion by the vertical force and the transverse force of the force sensor measuring rail wheeling action below the track girder.Calculate the derailing coefficient that passes through bend under the certain speed.
Ground floor plane rotatable platform P
1Balance platform P with inclining of the second layer
2Between running part be cover turbine one worm gearing 10, wherein turbine is fixed on plane rotatable platform P
1The edge, worm screw is fixed on to incline by the diaxon bearing balances platform P
2On, roll support mechanism has been adopted in the support between two-layer, the frictional resistance when reducing transmission; Platform P is balanced in inclining of the second layer
2Adopt screw mandrel one nut transmission mechanism 9 to transmit the pendular motion that inclines (finishing the superelevation simulation), being installed in inclines balances platform P
2The nut of below can be balanced the rotation of platform along with inclining and be rotated, and makes it not influence the rotation (seeing accompanying drawing) of inclining and balancing platform.Incline and balance platform by the 3rd layer of mobile platform P
3On the frictional resistance of four spacing roller supporting components 14 when bearing the gravity of locomotive and reducing swing.The 3rd layer of platform can be along laterally moving, and the same gear train that laterally moves has adopted screw mandrel---and nut transmission mechanism 11 comes transmitting movement, the 3rd layer of mobile platform P
3With the 4th layer of basic platform P
4Between adopted straight line roller bearing 17 to support the 3rd layer mobile platform.Reliable in order to guarantee ensuring smooth transmission, the gear train of lower two layers has designed universal coupling 18 in the end of screw mandrel, so that rotate more convenient, flexible.
The drive part of three running parts has all adopted driven by servomotor, because actual torque is bigger, servomotor 13 ends have installed the planet-gear speed reducer 12 of big speed ratio additional, have reduced the output torque of servomotor effectively, have satisfied the lower requirement of system's output speed simultaneously.
In addition, below the track 1, load sensor 2 is installed above test platform, this sensor can be measured horizontal and vertical power value, can satisfy the functional requirement that the locomotive car load is weighed; Can carry out wheel load respectively, axle is heavy and complete vehicle weight measurement.Simultaneously, because force transducer can be measured transverse force, when each gear train of adjusting platform moves according to certain speed coordination, can measure the derailing coefficient of locomotive under a certain speed like this according to derailing coefficient=wheel-rail lateral force ÷ vertical force.
Corresponding transmission position on multi-function test stand is equipped with the displacement transducer of stay-supported, and the rotation axis place of last rotatable platform is equipped with angular displacement sensor 5; Measure the displacement of the platform under each gear train drive respectively, so that control system coordinates to control the transmission speed of each.
Processed laterally on the rotatable platform on upper strata that " T " can adjust the installation site of sensor along "T"-shaped groove direction like this, and then reach the purpose that gauge is adjusted by shape guide groove 19.Each platform of testing table is installed in above the "T"-shaped guide groove track that is embedded in long rectilinear orbit, and single platform moves along the "T"-shaped guide groove guide rail of straight line and reaches the purpose that wheelbase is adjusted.
The adjustment of wheelbase is placed on position suitable on the track ground and gets final product as long as single platform is sling.
This multi-function test stand needs to adjust testing table according to the wheelbase of tested locomotive, vehicle, gauge at the trial, the utilization crane span structure (perhaps adopting crane) of getting on the bus makes motor supply shop enter the relevant position of (on falling) testing table, utilize the fixedly two ends of car body of reaction frame then, locomotive car body is fixed.Then control system according to the bend situation of reality finish locomotive, vehicle carries out the transition to the adjustment curve section again to the bend section from straight-line segment, carries out the transition to the real simulation of the overall process of straight-line segment again via the adjustment curve section, the state that reflection locomotive bend passes through.
Regulate each transmission speed of each unit by control system simultaneously, can finish the proving test of locomotive bend handling capacity below different speed.Measure the derailing coefficient of locomotive under different speed class simultaneously.Be limited to test condition, this test speed is limited in below the 60km/h.
, after testing table falls the position, also be under initial level, the guide rail linear state at locomotive, can carry out axle weight, the wheel load of locomotive, the test of complete vehicle weight at testing table.The system layout of testing table as shown in Figure 1, the thin portion structure of single stage body is seen Fig. 2---Fig. 5.
