Wheel-rail wear is a major issue in world's railway evolution.Test is the indispensable a kind of technological means of research wheel-rail wear.Bench run and road test are mainly contained to the abrasion test research of wheel track.The latter is closer to actual conditions, but cost intensive, not easily test separately the impact of certain factor on wheel-rail wear.Bench run economy is quick, and be convenient to test each factor to the impact of wheel-rail wear separately, meanwhile, test can reach various limiting condition.Therefore various forms of wheel rail relation testing table is developed in the world to study wheel-rail wear.
Comparatively difficult owing to carrying out orbital simulation in laboratory, what therefore modal wheel rail relation testing table adopted is wheel--wheel closes system test-bed, actual wheel simulated by the wheel that usual employing ratio makes, and simulate actual track with the rail wheel of another diameter, rail wheel and simulating wheel drive with motor respectively, two motor speeds are controlled all continuously, such wheel and rail wheel can realize different rotating speeds, the simulation to damped condition can be realized when rail wheel driving simulating wheel, the simulation to traction working condition can be realized when simulating wheel drive track is taken turns.Rail relation that the testing table of this form controls simple, and analog rate is high, but proves already from theory, adopts wheel--wheel relation replaces wheel--is carried out testing and be there is larger error, can not reflect real situation between wheel track.For this reason, abroad start to develop the testing table based on real wheel-rail relation.German federal railway research centre in 2005 have developed a kind of novel track switch and passes through testing table.This testing table adopts actual track switch and wheel to test.Track switch being installed in can on the slide block of straight reciprocating motion, and slide block drives to-and-fro movement by crank, thus switch with follow up movement to-and-fro movement, track switch and then drive vehicle wheel rotation, realizes the simulation to vehicle travel situations.2009, Japanese railway Technical Research Center have developed a kind of novel wheel track creep rate proving installation.Motor drives ball screw framework to drive bogie to do straight reciprocating motion on rail by rotating, realizes the simulation to vehicle travel situations.
In the testing table of above two kinds of wheel-rail relations, the former adopts crank block to realize the to-and-fro movement of track, even if well-known crank at the uniform velocity rotates, ram speed but changes always, and slide block can not remain a constant speed motion.If adopt this mechanism as the gear train of testing table, can accurately uniform motion operating mode in simulating vehicle actual motion.From the design feature of this mechanism, if the reciprocating stroke of track will be increased, the length of crank and connecting rod will be increased.The latter drives bogie to-and-fro movement in orbit by motor driven ball screws mechanism, just needs to control motor and constantly commutates, need consider the requirements such as buffering, comparatively bother.
Certainly realize to-and-fro movement and can also adopt pinion and rack, hydraulic motor transmission mechanism, hydraulic cylinder reciprocating mechanism etc.These mechanisms are all widely used in industrial circle, but these mechanisms exist straight reciprocating motion stroke not malleable, commutation process to shortcomings such as system shock are larger.
