Description
Technical field
The utility model designs a kind of electromagnetic emission armature.
Background technology
ELECTROMAGNETIC LAUNCH TECHNOLOGY utilizes the electromagnetic energy of emission system to be the technology being launched body kinetic energy.Rail EML device is made up of system units such as pair of parallel track, switch and power supplys usually; Being launched object is be clipped in the armature between parallel track.Emission principle is: electric current flows through armature from a guide rail and flows to another root guide rail, between two guide rails, form high-intensity magnetic field, and the Interaction Law of Electric Current of magnetic field and armature produces the Lorentz force pointed to guide rail parallel direction, promotes armature advance by Lorentz force.Armature is C type solid armature normally, because effectively can increase the area of electrical contact, the effect of Lorentz force simultaneously also makes armature produce small deformation and increase electrical contact performance.Because loading current is changing currents with time, obvious kelvin effect and proximity effect can be produced on guide rail and armature like this.Armature and rail portion region can be caused like this to produce higher current density, produce localized hyperthermia.High temperature may cause the strength of materials to decline.The part of armature and rail contact understands the phenomenon that generation current density too concentrates on a certain region equally
[4].Way rub will be caused like this under rubbing action between armature and track.The way rub that local overheating causes and low emission effciency are that restriction track ELECTROMAGNETIC LAUNCH TECHNOLOGY enters practical bottleneck.Therefore the structure improving armature becomes in prior art with the kelvin effect reduced and proximity effect the problem needing to solve.
Utility model content
For the deficiency of current techniques, the utility model provides a kind of rail mounted electromagnetic emission armature with magnetic conductor, it is characterized in that described rail mounted electromagnetic emission armature comprises C type solid armature and two magnetic conductors, described C type solid armature has the C type groove of through upper and lower surface, described magnetic conductor is the combination of sphenoid and laminar flange, described sphenoid comprises into the bottom surface of angle and wedge surface and the facade perpendicular to bottom surface, bottom surface is crossing with wedge surface forms wedge tip, facade matches with C type groove inner surface, bottom surface forms laminar flange protruding along direction, bottom surface with facade intersection, described two magnetic conductors weld or are pasted onto the two ends up and down of C type groove respectively, the facade of the magnetic conductor of installation and the boundary line of laminar flange are close to the edge line of C type fillistered joint close end, the laminar flange inner of two magnetic conductors of installation is fitted with C type solid armature upper and lower surface respectively, described magnetic conductor is more than or equal to the groove depth of C type groove to the ultimate range of wedge tip from facade.
The described rail mounted electromagnetic emission armature with magnetic conductor, is characterized in that described magnetic conductor facade is being not more than the half of flute length H2 of C type groove perpendicular to the height H 1 on direction, bottom surface.
The described rail mounted electromagnetic emission armature with magnetic conductor, is characterized in that two magnetic conductors of installation are symmetrical about the center cross-sectional of C type groove;
The described rail mounted electromagnetic emission armature with magnetic conductor, is characterized in that the upper and lower surface of the laminar flange of two magnetic conductors of installation all or part of covering C type solid armature.
Described wedge surface is plane or curved surface, and described curved surface can be parabola face, hyperbola face or oval calotte.
Described C type solid armature by electric conductivity better and the less material manufacture of hardness, magnetic conductor is by the ferrimagnet manufacture containing iron, cobalt, nickel, the described ferrimagnet containing iron, cobalt, nickel is selected from soft magnetic material, without magnetized hard magnetic material or rectangular hysteresis material.
The rail mounted electromagnetic emission armature with magnetic conductor that the utility model provides, by adopting the wedge shape magnetic conductor with the laminar flange that can cover C type solid armature C type groove ends, after machine emulation, find that the rail mounted electromagnetic emission armature of this structure only has the middle very little part of C type solid armature to there will be the excessive phenomenon of current density in whole emission process as calculated.This region is away from guide rail; Simultaneously other parts of armature and comparing evenly with the current density of guide rail contact part, do not have the phenomenon that obvious current density is excessive.In guide rail, current induced magnetic field is imported in armature by magnetic conductor, adds armature and obtains more magnetic field, namely makes armature obtain larger thrust.Due to the interaction in magnetic field, also deformation can be there is because of electromagnetic force in two other guide rail when launching.When adopting the rail mounted electromagnetic emission armature of rail mounted electromagnetic emission, be imported in armature because guide rail produces magnetic field, influencing each other of guide rail can be reduced accordingly, be conducive to the reliability increasing electrical contact.
