Background technology
Electromagnetism performer is a kind of execution device driving displacement based on electromagnetic conversion principle, and compared with other performer, electromagnetism performer has the advantage such as high frequency sound, high precision, thus obtains and pays close attention to widely. In recent years, under the promotion of new demand and novel material, new technology, especially the widespread use of the permanent magnet material such as sintered NdFeB, makes electromagnetism performer obtain bigger development.
Its principle of work of consideration that the electromagnetism performer of present stage is one-sided and mode of operation, do not consider that the loss of performer and temperature rise are on the impact of performer, actuator performance can be produced bigger impact by loss and temperature rise, mainly may be embodied in the following aspects: the energy waste of electromagnetism and mechanical aspects can reduce the economy of performer so that it is energy conversion efficiency reduces; The ability of the size of loss and limit work is closely bound up, and the increase of loss can reduce the working limit of performer; Loss also can increase the tired degree of system, the reliability of reducing mechanism long-time stable work; In addition the temperature rise working and causing for a long time, the reliability of meeting influential system and the linear action of electromagnetic coupled field, and then affect the motion precision of performer, even performer can be caused damage.
In order to loss and the temperature characteristic of effective analyses executor, reduce nonlinear object unnecessary in work, contriver with have employed theory in the analytical procedure of loss and tests the method combined in electromagnetism performer temperature rise, together with theoretical analysis is combined in test, simultaneous test on the basis of theory, the analytical procedure of the present invention is proposed, can the loss of analyses executor accurately and temperature rise, reduce loss unnecessary in working process, for falling of electromagnetism performer is damaged and temperature rise is followed compensation and laid a good foundation.
Summary of the invention
In order to overcome the deficiencies in the prior art, the present invention proposes the analytical procedure of a kind of electromagnetism performer temperature rise and loss characteristic, object is to analyse in depth temperature rise and the loss characteristic of electromagnetism performer, set up and obtain temperature rise and the Dissipation change rule of electromagnetism performer, the loss form of identification and assessment electromagnetism performer;Consider the heat trnasfer factor of electromagnetism performer inside, study its distribution law of temperature field, obtain the temperature characteristic of electromagnetism performer under different controling parameters, simultaneously for falling of performer is damaged and formulated the method for actuator control that temperature rise follows compensation and lay the foundation.
For solving the problems of the technologies described above, the analytical procedure of the present invention adopts analysis conclusion and the test-results of the electromagnetism performer of contrast different parameters, through progressive, different theoretical models and trial model is combined, it is achieved precisely analyze.
The electromagnetism performer temperature rise of the present invention and the analytical procedure of loss characteristic, on the basis of theoretical analysis and experimental examination, consider the temperature rise of electromagnetism performer under different controling parameters and loss, the research temperature field of electromagnetism performer and loss distribution rule, learn the best or preferably temperature rise and loss characteristic.
