Description

The sextuple vibration of EMU catamaran type power train assembly reliability test bench
Technical field
The utility model relates to a kind of rail vehicle power train assembly parameter detecting test platform, and more particularly, the utility model relates to the sextuple vibration of a kind of EMU catamaran type power train assembly reliability test bench.
Background technology
At present, China's motor train unit technical development is rapid, has reached 350km/h in the motor train unit max. speed of operation, and the motor train unit max. speed in development approaches 500km/h.Along with the raising of train running speed and the increase of vehicle axle weight load, the vibration aggravation between vehicle and track, vehicle smoothness reduces, and the security of train and riding comfort problem become increasingly conspicuous.
According to the analysis of train fault in actual motion is shown, the weak link when power train of bullet train is train high-speed cruising.Power train is because transmitting torque is very large, and gear rotational speed is too high and bear the factors such as Vehicular vibration is excessive, tends to occur the faults such as traction electric machine bearing breaking, inner gear of the gear box gummed, fracture and shaft coupling breakage.If these faults occur in bullet train actual motion, will produce serious traffic hazard, China's people's lives and properties are sustained losses severely.Detect EMU power train reliability technical development has good impetus to High Speed Train in China so build a system of reliability test bed for drive line of high-speed motor train, there is very high Social benefit and economic benefit.
At present, quite ripe to the development of the vehicle transmission system reliability detection technique including track train and automobile both at home and abroad.Chinese scholars and research institution have worked out several different methods detects the fatigue reliability of Transmission gears case or traction electric machine, but these methods are all that power train middle gear case or traction electric machine are separated respectively and studied.Such research method has certain effect, can be to the fatigure failure analysis of causes of a certain parts of power train comparatively thorough.But, train power train in actual motion is done as a whole stressed, wherein all parts of power train, in the effect of influencing each other, has significant limitation with regard to the method that makes parts of single consideration carry out fail-test like this, also comprehensive not to the evaluation of power train reliability.Meanwhile, be subject to very large vibration when train orbits, along with the raising vibration of the speed of a motor vehicle can be larger, power train is subject to pulsating stress effect generation fatigure failure.If power train is put in static environment, it is also completely nonsensical not having to carry out fail-test under the condition of external drive.
The utility model is the sextuple vibration of EMU catamaran type power train assembly reliability test bench, under the operating mode of dry run track vibration, make the normal output torque of tested kinematic train, bearing load simultaneously, and then the problem of fatigue damage of high-speed train kinematic train (comprising traction electric machine and retarder system) is discussed in research, provide respectively the fatigure failure situation of traction electric machine, shaft coupling and speed reduction unit in train kinematic train, point out which part in kinematic train is the weak link in train operation.Thereby optimize manufacturing and designing of train, guarantee the security and stability of train high-speed cruising.In a word, development and production, experimental study, theoretical research and quality control and the shortening product development cycle etc. of the exploitation of the sextuple vibration of EMU catamaran type power train assembly reliability test bench to track vehicle transmission system product is all of great importance, and has wide economic benefit and social benefit.
