摘要： An eddy current damper (1) includes a magnet holding member (2), a first permanent magnet (3) having a thickness (HI), a second permanent magnet (4) having a thickness (HI), a conductive member (5), a ball nut (6), a screw shaft (7), and a copper layer (12) having a thickness (H2). The second permanent magnet (4) is adjacent to the first permanent magnets (3) with a gap therebetween in the circumferential direction of the magnet holding member (2), wherein the arrangement of magnet poles is inverted between the second permanent magnet (4) and the first permanent magnet (3). The ball nut (6) is arranged inside the magnet holding member (2) and the conductive member (5), and is fixed to the magnet holding member (2) or the conductive member (5). The copper layer (12) is fixed to the conductive member (5) and is opposed to the first permanent magnet (3) and the second permanent magnet (4) with a gap therebetween. The thickness (H1) and the thickness (H2) satisfy, with respect to a distance (R1) between a central axis of the screw shaft (7) and the center of gravity of the first permanent magnet (3): 0.018 ≤ H 1 / R 1 ≤ 0.060 , and 0.0013 ≤ H 2 / R 1 ≤ 0.0065 .

摘要： A disclosed front axle beam (100) includes a beam section (110). The beam section (110) includes a first flange part (131), a second flange part (132), and a web section (120) connecting the first flange part (131) and the second flange part (132). The web section (120) includes a varying-slope section (121) that includes a plurality of first slope sections and a plurality of second slope sections. Each of the plurality of first slope sections inclines in one direction with respect to the vehicle-height direction in a cross section perpendicular to the longitudinal direction (LD). Each of the plurality of second slope sections inclines in the opposite direction to the one direction with respect to the vehicle-height direction in a cross section perpendicular to the longitudinal direction (LD). The first slope section and the second slope section are located in an alternate manner along the longitudinal direction (LD). In this way, the rigidity of the front axle beam (100) can be increased.

摘要： An eddy current deceleration device (100) includes a rotor (10) and a stator (20). The rotor (10) includes a hub (12), a rotor body (11), and a spoke (13). The spoke (13) has neutral axes (N1, N2). The neutral axis (N1) is a neutral axis when the spoke (13) is bent in a circumferential direction of the rotor body (11). The neutral axis (N1) is positioned forward in a rotating direction (R) of the rotor (10) with respect to a center line (C1) of the spoke (13) in the circumferential direction. The neutral axis (N2) is a neutral axis when the spoke (13) is bent in an axial direction of the rotor body (11). The neutral axis (N2) is positioned on a rotor body (11) side with respect to a center line (C2) of the spoke (13) in the axial direction.

摘要： The production method disclosed includes a first step, a second step and a third step to be performed in this order. In the first step, a steel material is forged by dies, whereby a forged product including a rough web part (220) and four plate-shaped rough flange parts is produced. In the second step, at least one specified rough flange part, which is at least one of the four rough flange parts, is pressed by a first die, whereby a first bent portion bending outward in an up-down direction VD of the forged product is formed in the specified rough flange part. In the third step, the edge of the first bent portion is pressed by a second die (320) inward in the up-down direction VD, whereby the edge is deformed and a second bent portion (232b) is formed. In the third step, the edge of the specified flange part is deformed while the edge is kept from deforming in a front-rear direction HD.

摘要： An eddy-current rail brake device (1) includes a row of magnets (10), a supporting member (3), a case (4), and a lifting device (5). The row of magnets (10) includes a plurality of permanent magnets (2) that are arranged in a traveling direction of a railroad car. To the supporting member (3), the row of magnets (10) is mounted. The supporting member (3) has magnetism. The case (4) houses the row of magnets (10) and the supporting member (3) and includes a bottom portion (8) that faces the row of magnets (10) and is non-magnetic. The lifting device (5) raises and lowers the supporting member (3) inside the case (4) while the row of magnets (10) is kept facing the bottom portion (8). The eddy-current rail brake device (1) can prevent or reduce adhesion of a foreign object and can be reduced in size in a right-left direction.

摘要： An eddy current damper (1) includes a screw shaft (7), a plurality of first permanent magnets (3), a plurality of second permanent magnets (4), a cylindrical magnet holding member (2), a cylindrical conductive member (5) having a conductivity, and a ball nut (6) meshing with a screw shaft (7). The screw shaft (7) is movable in the axial direction. The first permanent magnets (3) are arrayed along the circumferential direction around the screw shaft (7). The second permanent magnet (4) is arranged between the first permanent magnets (3) leaving gaps with the first permanent magnets (3), wherein the arrangement of magnet poles is inverted between the second permanent magnet (4) and the first permanent magnet (3). The magnet holding member (2) holds the first permanent magnet (3) and the second permanent magnet (4). The conductive member (5) is opposed to the first permanent magnets (3) and the second permanent magnets (4) with a gap therebetween. The ball nut (6) is disposed inside the magnet holding member (2) and the conductive member (5), and is fixed to the magnet holding member (2) or the conductive member (5).

摘要： In a pressing step, a first forged product (201) is pressed by a first die (310), and thereby, a second forged product (202) including a rough flange (241) having a thickness-changing portion (141) is produced. The thickness-changing portion (141) includes a front part protruding frontward from a side of a rough web part (220) and a rear part protruding rearward from the side of the rough web part (220). Each of the front part and the rear part includes a first part, and a second part that is thicker than the first part and is located farther from the rough web part than the first part. In the pressing step, at least a part of the rough flange that is above or below the web part (thick part) is pressed by the first die (310), whereby the material of the first forged product in the part is caused to flow frontward and rearward, and the thickness-changing portion (141) is formed.
