Shapovalov A. Increasing the capacity to work of the tractive engines of electric locomotive

Dissertation is devoted to increasing the capacity to work of the tractive engines of electric locomotive in modern condition of the working the railways of the Ukraine by improvements quality to switchings to account of the determination of the rational deflections on sizes of the details magnetic chain additional pole of the tractive engines constant and pulsing current during their fabrications and repair. As a result of the executed scientific researches, the following is in-process got: the method, which for the first time provides the receptions a degree sparkling with provision for influences of the deflections geometric parameter element magnetic chain additional pole is designed, as well as theoretical determination of these deflections on the base statistical given with use the theories of the dimensioned chains that enables more exactly define the quality to switchings under different working state of working tractive engines electric locomotive; quantitative dependencies degree sparkling are received from importances of the deflections air clearance magnetic chain additional pole in comparisons with nominal clearance that enables to promote the improvement to switchings; the methods estimations of the influence of the deflections air clearance magnetic chain additional pole on quality of the switchings under connecting process by means of designed mathematical model have got the most further development.
