Description

Asynchronous traction motor four-dimensional movement comprehensive testing method and testing table and purposes
Technical field
The invention belongs to a kind of test method and device, is a kind of asynchronous traction motor test method and multi-function test stand specifically, is mainly used in dynamic (dynamical) test that simulation is correlated with under the fully loaded condition to traction motor.The invention still further relates to the purposes of described multi-function test stand.
Background technology
Popular in the world rolling rig, carry out compbined test and dynamic (dynamical) performance test of the electric property of system at scroll wheel with the bogie frame of simulation, because bogie will be on the fixed mount that vertically is pulled in ground, be used for the tractive force of balancing steering frame power wheel to producing.Each power wheel is to applying axial force separately in process of the test, like this can't be in axial dynamic (dynamical) test of under the fully loaded condition, being correlated with on the traction motor, in case axially associated components breaks down and need go assessment after post-installation review is out of joint, loses huge.Some key issue may relate to several parts, can't determine accurately which parts goes wrong, and such problem is difficult to assessment, has a strong impact on the evaluation of traction motor structural reliability.
With " pioneer " number asynchronous traction motor example: the time of having changed several years is on rolling rig, test all is good on the ring of Tie Keyuan, but in actual motion because complex circuit, cause motor location bearing and shaft coupling all to damage, this is because the bearing of motor on earth, or the end cap of motor, or globe joint shaft coupling, still go wrong in the bogie installation site, cause system's cisco unity malfunction, so far also take out convictive quantitative data in not, had a strong impact on the exploitation of China's high speed motor car, so cause our invention thinking.
On the rolling rig on ring the torque of traction motor can not directly measure.Can only estimate.Address this problem and to have leaned on the testing table of motor, but on popular motor experiment platform, accompany the necessary strictness of examination motor, tested motor and tachometer torquemeter point-blank, otherwise clutch itself, the axle and the bearing of motor reel and bearing, tachometer torquemeter can sustain damage.And need when four-dimensional high speed rotating, to accurately measure torque now, also must the novel testing table of exploitation.
In carrying out the patent inquiry, still find no similar open source literature, only inquire the most approaching Chinese patent name and be called " motor experiment device ", the patent No. is 00217634.3 patent documentation, but this patent adopts the step-less adjustment motor load to come test motor only by shaft coupling and the threephase asynchronous motor to be measured that links.And for considering influence to motor to be measured from a plurality of force directions that are subjected to.
In sum, existing various test unit all can not satisfy the accurate mensuration of traction motor torque rotary speed under the four-dimensional movement condition, for accurately searching the existing problem of traction motor, there is certain difficulty, therefore necessary exploitation or invent a kind of comprehensive test system, quantitative test goes out the subsystem relevant with asynchronous traction motor, goes the physical quantity of vitals in motion process in the quantitative capturing system, and these physical quantitys are the necessary data of assurance system reliably working.
Summary of the invention
The objective of the invention is to deficiency at existing test unit, propose the quantitative test of a kind of energy and go out the subsystem relevant, remove the asynchronous traction motor multi-dimensional movement test method and the multi-function test stand of the physical quantity of vitals in motion process in the quantitative capturing system with asynchronous traction motor.
