CJ/T 413-2012 3.1 F-shaped steel The special steel for medium and low speed maglev track with the section of shape F which consists of innermagnetic pole, outer magnetie pole, induction section and fastening section. 3.2 induction plate The secondary part of linear induetion motor used for train traction, which adopts non-magnetic conductive material and is installed on F-shaped steel. 3.3 F-shaped rail A kind of fundamental component bearing the suspension force, guiding force and tractive force of maglevvehicle, which consists of F-shaped steel and induction plate. The parts of F-shaped steel on the opposite of both magnetie pole plates of maglev electromagnet arerespectively named as inner magnetic pole and outer magnetic pole of R-shaped rail. The two end faces of innermagnetic pole and outer magnetic pole are named as magnefie pole face. The lower surface of F-shaped steelinduction section is named as levitation detection surface. 3.4 sleeper Fundamental components used for connecting F-shaped rails and keeping relative position of F-shaped railsand beam body fixed and transferring load. 3.5 track panel Basic function unit of mediam and low speed maglev line which has the function of supporting maglevvehicles, bearing vehicles'leyitation force, guiding force and tractiye force. Track panel consists of F-shaped rails, sleepers, fasteners, ete. which may includes: a)Straight track panel, of which the centre line is straight; b)Circular curve track panel, of which the centre line is a circular curve; c) Transition curve track panel, of which the centre line is a transition curve. Note 1:Track panel length refers to its centre line length. Note 2:Centre line of track panel refers to the symmetry centre line of the two F-shaped rails. 3.6 sleeper spacing The distance between two adjacent sleepers. 3.7 joints Connecting device between adjacent track panels. 4 Service conditions 4.1 Environmental conditions 4.1.1 Altitude:≤1400m. 4.1.2 Ambient temperature:-25℃ to +45℃. 2
