Technical field
The invention belongs to field of electromechanical technology, more particularly, to a kind of impeller containment test method.
Background technology
The reliability of the rotor of rotary blade machinery is extremely important, and power or manned aerial winged is operated for certain someone
For row device, the accident even if generation impeller disperses does not allow fragment to fly out yet and injures people, or punctures the crucial portion of aircraft
Position.For this purpose, when the turbomachine sizing of certain model, a large amount of containment test research will be carried out, specified conditions are manufactured, make impeller
It disperses when under defined rotating speed, to study destruction situation of the fragment to containing component.
General method is to analyze stressing conditions of the impeller under limiting condition by simulation means, on this basis, right
Blade root is slotted or is punched, and by repetition test, modification fluting or downhole parameter, after more round experiments, testpieces flies
Scattered rotating speed is finally reached design requirement.
For example, the turbo-charger blower impeller containment test requirement of internal combustion engine industry, experiment must be in rated speed
Impeller disperses when 120%, rotating speed deviation≤5%.But the rotating speed that disperses of impeller is often difficult to control when testing, sometimes impeller exists
Just disperse when not reaching egulation rotating speed, also sometimes impeller more than it is defined disperse rotating speed when do not disperse also.
To find out its cause, be more because influencing the factor dispersed of impeller, the calculated results are caused to be difficult and actual conditions
Unanimously.So the containment test of impeller is classified as a kind of content of the test of more difficult completion by researcher.
Invention content
In view of this, the present invention is directed to propose a kind of impeller containment test method, for meeting impeller containment test requirement,
Testpieces can be made to disperse under defined rotating speed, rotating speed deviation is small.Test accuracy is improved, test number (TN) is reduced, is reduced
Research cost.
In order to achieve the above objectives, the technical proposal of the invention is realized in this way：
A kind of impeller containment test method, including following content：
1) before testing, according to the runner processing briquetting of testpieces impeller, briquetting is consistent with the hub size of impeller, the pressure
Block center is equipped with the inner cavity for being set with impeller blade end to be measured, and briquetting is used to impeller sets to be measured conjunction being pressed together；
2) it is cut into testpieces impeller in parts uniformly several parts along rotation angle, impeller and briquetting is combined into progress
Dynamic balancing；
3) before rotating, by quick cylinder combination thrust disc, so that briquetting and impeller is not detached in rotary course, push away
Power disk is contacted with briquetting；
4) axis of impeller and briquetting is driven across by motor, driving impeller is rotated；
5) so that axis is reached preset rate when motor drives, then control quick cylinder and shrink, so that briquetting and impeller is generated and divide
From impeller disperses under set rotating speed.
Compared with the existing technology, the method for the present invention has the advantage that：
The present invention can make testpieces disperse under defined rotating speed, rotating speed is inclined for meeting impeller containment test requirement
Difference is small.Test accuracy is improved, test number (TN) is reduced, reduces research cost.
