Description
Technical field
The invention belongs to technical field of measurement and test, and in particular to it is a kind of suitable for non-pulling wheel Xuan lathes to the polygonal measuring method of wheel of Railway wheelset.
Background technology
In train travelling process, if there is failure, the operation security implication to train is huge, and influence is also brought on passenger's ride quality, and wheel plays safely conclusive effect to the critical component as train operation to guarantee train.High-order polygon occurs in wheel can cause operating train high frequency strenuous vibration occur, these vibrations can trigger a series of train fault, cause train other superstructure loosenings, circuit rail is caused to loosen, wheel and rail abrasion accelerate, have a strong impact on the operation safety and service life of train, or even the life security for jeopardizing passenger.Therefore, finding that wheel polygon hidden danger is to ensure that train is safe and efficient, high-speed cruising important measures in time.
At present at home, rapid, automatic measurement polygonal to wheel still belongs to blank, main to carry out single wheel to measurement using the external portable equipment introduced.For the high ferro EMUs for needing rapid-maintenance, it has following defect for this：One be it is cumbersome, it is necessary to carry out the connection before big measurement and measurement after debugging evaluation work；Two is higher to operating personnel's degree of specialization requirement；Three is expensive apparatus value, increases user cost；Four is to be not easy to maintenance and repair；Five is extremely low measurement efficiency, and measurement place is also required, therefore, this mode is difficult to meet actual demand of the wheel to measuring.
The content of the invention
It is low in order to solve the problems, such as to take turns, efficiency high to polygon testing cost in the prior art, a kind of present invention offer non-pulling wheel Xuan lathes realize the polygonal measuring method of wheel of inexpensive, accurate, rapid automation to the polygonal measuring method of wheel.
The technical proposal of the invention is realized in this way：Non-pulling wheel Xuan lathes are as follows to the polygonal measuring method of wheel, including step：
（1）The axially measured wheel of measurement apparatus is contacted to the datum level of wheel inner side at A using non-pulling wheel Xuan lathes；
（2）The coordinate data of storage wheel inner side datum level；
（3）Safe retraction measurement apparatus；
（4）The radial measurement wheel of measurement apparatus is contacted to the rolling basic circle of wheel profile；
（5）To be taken turns to rotation using non-pulling wheel Xuan lathes, measurement apparatus are continuously uninterruptedly scanned complete one week along wheel circumference direction；
（6）Store the actual geometric data of wheel profile；
（7）Safe retraction measurement apparatus；
（8）By the data of wheel profile are filtered, denoising, interpolation processing；
（9）Draw out the geometry situation of change of wheel circumferentially each phase；
（10）Converted by data, draw out the waveform trend cycle of wheel geometry change；
（11）By FFT, obtain changing order situation in the polygon of frequency domain, calculate the roughness levels under the polygonal order situation of wheel and the order, draw order figure；
（12）Finally, the roughness levels of the polygonal true order of wheel and maximum are determined.
The wheel that the present invention can be used to instruct non-pulling wheel Xuan lathe process to wear away is right, to eliminate wheel polygon, makes wheel closer to preferable circle, so as to remove a hidden danger.Take turns to left and right wheelses respectively using left and right measurement apparatus calculating is measured using same method, this method can also measure the rolling circumference of different model.
The present invention utilizes existing place and hardware condition, many disadvantages of portable equipment is overcome, with advantages below：One is simple to operate, can be automatically performed all measurement process, is not required to manual intervention；Two is that operating personnel are required without specialty, only need to pay close attention to its measurement process；Three is that increased cost is extremely low；Four are easy for maintenance maintenance, its maintenance maintenance content for belonging to non-pulling wheel Xuan lathes；Five is measurement efficiency high；Six is accuracy high, and its part for belonging to Digit Control Machine Tool simultaneously uses contact type measurement, authentic and valid；Six is good measurement reproducibility, without artificial error component；Seven can be the polygon situation of the basic circle that measurement is specified, and different focus are shot the arrow at the target.The present invention can effectively ensure the quick detection maintenance of train, ensure train operating safety, improve social benefit and also improve economic benefit indirectly.
