Description
Technical field
The present invention relates to a kind of rail vehicle damper parameter detecting experimental rig.
Background technology
At present, EMU technology in China's is quickly grown, and has reached 350km/ in the EMU max. speed of operation
H, the EMU max. speed in development is already close to 500km/h.With the raising of EMU travel speed and axle for vehicle heavy duty
The aggravation of lotus, the vibration aggravation between EMU and track, EMU running stability reduce, the security of EMU and operation
Steady sex chromosome mosaicism becomes increasingly conspicuous.The maintenance of damper is the important component of overhaul of train-set, is to ensure that EMU safely may be used
By the key of operation.
Concussion when damper is mainly used to suppress to rebound after spring shock-absorbing and impact from ground or track, are
Rapid wear accessory in train travelling process, damper work quality, by the stationarity for directly affecting train driving and other parts
Service life.Therefore, we should make damper often in good working order.
It is mostly hydraulic damper that damper is used in train suspension system, its operation principle is to work as vehicle frame (or vehicle body) and car
When being shaken between bridge and relative motion occur, the piston in damper moves up and down, and the fluid in snubber cavity is just repeatedly from one
A chamber flows into another intracavitary by different holes.Friction between hole wall and fluid at this time and the intermolecular interior friction pair of fluid
Vibrations form damping force, thump energy is converted into fluid thermal energy, then be dispersed into by absorber in air.
At present, common damper testing stand has mechanical, computermatic and electro-hydraulic servo formula etc., mechanical damping
Device testing stand is mainly two kinds of forms of crank connecting link and upper and lower slider-crank mechanism, but at the same time there are shortcomings, such as exciting frequency
Rate scope is relatively narrow, test method not science, mechanical device in high frequency inertia big serious wear the problems such as.Computermatic
Can testing stand can complete the detection of the model center building of variety classes damper, speed characteristics and temperature characterisitic, computer control
System acquisition corresponding data simultaneously includes it in visual information equipment, and data are by computer disposal, as a result again by corresponding
Control system realizes the closed-loop control to equipment.Electro-hydraulic servo formula testing stand can produce higher during damper performance test
Excited frequency, significantly improve measurement accuracy, meanwhile, under high-speed case, noise and abrasion also solved well.It is but domestic
The development of correlation test platform is later, major part or the imports of technique by foreign countries, and damper correlation test platform is first also in development
Phase, so being badly in need of high-performance, high-precision, inexpensive damper testing stand.
