Description

Dynamic power machine closed loop tilting polygon exciting gear box test table

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.
