Description
Technical field
The present invention relates to a kind of vibration impact experiment platform, suitable for permanent magnet direct driving motor used for rail vehicle impact with shaking
Dynamic test.
Background technology
Permanent magnet direct-drive bogie is different from conventional bogie, replaces traditional asynchronous machine using permagnetic synchronous motor, adopts
With installation direct drive axletree mode is seized, mounting structure, rotor and axletree one are seized, directly drives axletree.Its electricity
Machine quality is big, and the maximum load and frequency range of existing vibration mechine can not meet permanent magnet direct driving motor vibration examination simultaneously
Test requirement；Electrical installation is different from conventional motors, need to check motor bearings vibrating fatigue performance, traditional vibration mechine
The vibrating fatigue check to bearing can not be realized；From traditional motor using motor hanger as impact shock source different, permanent magnet direct-drive
Electromechanical shock load derives from rotor, and traditional vibration mechine can not meet experiment demand.
And according to conventional vibration shock table mentality of designing, construction super large load vibration mechine cost is too big and can not
Real simulation permanent magnet direct driving motor vibratory impulse operating mode, it is impossible to adequacy test demand, while very big economy can be caused to enterprise
Burden.
Consider economic factor and enterprise's experiment hardware facility, a kind of vibration suitable for permanent magnet direct driving motor of exploitation is rushed
It is very necessary to hit testing stand.
The content of the invention
The technical problems to be solved by the invention are to overcome the disadvantages mentioned above of prior art, there is provided a kind of permanent magnet direct-drive electricity
Machine vibration shock table, testing stand is safe and reliable, and test measurement data precision is higher, fully achieves the expected mesh of experiment
, a whole set of testing equipment cost is relatively low, greatlys save testing expenses.
In order to solve the above technical problems, permanent magnet direct driving motor vibration impact experiment platform provided by the invention, its feature exist
In with：
Hydraulic actuator, for applying downward power to bogie, to simulate car body vertical load；
Straight track, for carrying the pair of wheels on rear side of bogie, to this to wheel lock, realize bogie in longitudinal direction
On locking；
Rail wheel, for carrying and driving the pair of wheels on front side of bogie, at least there are two sections of circles in the outer counter of rail wheel
Arc, their radius differ A, are to seamlessly transit between circular arc；By the driving of rail wheel, make the pair of wheels on front side of bogie
Rotate and produce the vibration of vertical direction, the amplitude of vibration is A；
Motor, for driving rail wheel to rotate.
The present invention is carried and driven to subject end wheel using the rail wheel of non-circular design so that rail wheel rotates
When, subject end wheel vibrates while rotation, and rotor of permanent magnet direct driving motor, can with wheel synchronous axial system during this
Simulated machine rotor is hit in rotation, and can realize the vibrating fatigue check to bearing.
The ingenious part of the present invention is：The vertical vibration of subject end wheel is obtained using the rotation of rail wheel.Experiment
Platform is reasonable in design, is easily installed, dismantles, reusable, suitable for permanent magnet direct driving motor vibration impact experiment, both solves
The problem of existing vibration impact experiment platform maximum load deficiency, also solve conventional motors vibration fatigue test platform can not be true
The problem of reducing bear vibration operating mode.Avoid the time caused by the conventional vibration test bench location for reconstructing the adaptation vehicle
Waste on cycle and financial resources, the financial cost burden caused by buying professional equipment is turn avoid, experiment shows, present invention examination
Test the security of platform, feasibility is all sufficiently verified.
