Description
Technical field
This utility model relates to a kind of rail vehicle Train Parameters detection test platform, and more specifically, this practicality is new
Type relates to a kind of dynamic power machine closed loop tilting polygon exciting gear box test table.
Background technology
Currently, the development of High Speed Train in China technology is advanced by leaps and bounds, and a new generation's the highest operating speed of EMUs has reached
380km/h, the highest test speed of EMUs of up-to-date development is already close to 600km/h.The raising of train running speed and car
The lifting of axle heavy load makes to take turns and aggravates the vibration between track, and wheel in the process of moving gradually wear out and
With the continuous shock of rail, wheel rim is caused to be gradually become the irregular of surface irregularity by ganoid regular circle shapes
Polygonal shape.Wheel rim surface irregularity the most persistently can produce impulsive force and cause shaking of whole train
Dynamic, bullet train travel speed is higher in addition, causes vibration more violent, it will to cause axletree on train, bearing, gear-box etc.
The judder of important spare part, may produce the resonance acceleration of 30g~70g, cause bearing to rupture, gearhousing time serious
The problem that fragmentation body etc. are more serious, is directly connected to stationarity and the safety issue of train operation.
Existing railway vehicle gear case detection method major part is all the failure mode according to the gear-box occurred
Set certain operating condition of test and gear-box is carried out fail-safe analysis, and gear-box is in the actual motion of rail vehicle, can be subject to
To stress and the vibration of different directions, its fault is probably the superposition of various of failure, therefore existing detection method cannot be true
The failure cause of reflection rail vehicle actual motion middle gear case.Gear-box reliability test belongs to destructive testing, only makes
Gear-box produces fatigue rupture under bad working environments, could go out its failure mode and reason by Precise Diagnosis, therefore existing detection method
Cannot realize rail vehicle actual motion carries out reliability test to gear-box.Meanwhile, make due to the speed-raising of EMUs
Obtaining gear-box and must also be fulfilled for the reliability requirement under high-speed working condition, testing stand is just driven the power of motor to propose higher by this
Requirement, existing gear box test table is mostly to test under open loop situations, not only needs the driving motor of relatively high power,
Also result in energy waste in process of the test.
