摘要： PURPOSE:To provide light and strong out-of-plane rigidity and suppress the lowering of magnetic permeability by making a panel wherein high magnetic permeable metal panel is used for at least one front member out of two front members and light alloy metal plate is used for the other front member and honeycombs made of light alloy metal is used for cores and these front member and core material are brazed. CONSTITUTION:A honeycomb structured core 3 made of light allay Al alloy, for example) is held between a front member 1 made of high magnetic permeable metal and a front member 2 made of light alloy Al alloy, for example), and these are connected to each other by brazing to constitute a magnetic shield material 10. In this case, a highly magnetic permeable plate on which light alloy 4 is plated beforehand is used for the front member 1. Thus, the highly magnetic permeable plate 1 is supported by the honeycomb panel 3, as a whole. Since this constitution provides the same effect as that in the case where fine mesh grid-like skeletons are arranged, high strength and out-of-plane rigidity can be given to the magnetism shield material itself without employing reinforcing skeletons.

摘要： PURPOSE:To obtain a light weight magnetic shield excellent in shielding by disposing a magnetic member having higher permeability and saturation magnetic flux density, as compared with other parts, between superconducting coils facing the opposite side parts at the end of a superconducting coil group in the advancing direction of vehicle. CONSTITUTION:A magnetic shield member 62 disposed inside a car body 11 comprises a U-shaped main magnetic shield plate 62a thin enough not to be saturated magnetically disposed on the floor of the car body 11 and the region under the side wall. Sub-magnetic shield plates 62b, 62c having higher permeability and saturation magnetic flux density than other parts are disposed in the regions proximate to superconducting coils 21a, 21c facing the superconducting coils on the other side disposed at the opposite ends in the advancing direction of the vehicle where the leakage flux and the flux density are high. Since a circuit for shunting most of leakage flux from the superconducting coils 21a, 21c to the sub-magnetic shield plates 62b, 62c is established, flux leakage into the vehicle can be reduced significantly.

摘要： PURPOSE:To prevent the magnetic flux entering a through-passage, allow the relative displacement between vehicles, and keep the airtightness of the through- passage. CONSTITUTION:Parts of magnetic shield sheets 1, 2 are overlapped with appropriate space, and the magnetic shield sheets 1, 2 are connected to each other with a hood 5. The magnetic flux passing through the clearance of the magnetic shield sheets is guided to the outer magnetic shield sheet, and the leakage of the magnetic flux into a through-passage can be prevented. The airtightness of the through-passage part can be secured by connecting the clearance between the magnetic shield sheets with the hood without interfering the relative displacement between the vehicles.

摘要： PROBLEM TO BE SOLVED: To reduce the vibration caused by the air separation occurring in the tail vehicle of a high speed rolling stock during running by spoilers of the rolling stock. SOLUTION: Movable spoilers 1, 2 and 3 are mounted on the rear section 10a of the body 10 of the tail vehicle of the high speed rolling stock. The spoilers 1, 2 and 3 are provide with their respective openings 11, 12 and 13 opening to the body 10, and a cylinder is arranged in each of the openings, and each cylinder is attached to the end of each opening through a hinge so as to open and close each opening by expanding and contracting the rod 4 of the cylinder. When the spoilers are erected, the flow of the separated air is separated by the faces of the spoilers from the surface of the vehicle, which also separates the generated eddy from the surface, resulting in reducing the vibration caused by this eddy.

摘要： PURPOSE:To hold a relative position between a pantograph and an overhead power line when a vehicle passes a curved part and to enhance riding comfort without complicating truck fairing and vehicle external appearance. CONSTITUTION:A floor inclining device 10 installed inside of a car body 2 of a rolling stock 9 is constituted of hydraulic cylinders 4 erected on both right and left sides of a bottom of the car body 2, and a floor 3 supported by rods 11 of the cylinders 4. In the case of traveling a curved part at a speed lower than that estimated at the time of cant determination (a), a component of gravitational force acts in the inward direction of the curve because of shortage of centrifugal force. At this time, inside the car body 2, the hydraulic cylinders 4 are operated to incline the floor 3 in the direction reverse to a track surface 8 so as to cancel the shortage of centrifugal force. Since influence of the centrifugal force upon passengers is thus cancelled, excellent riding comfort can be secured even in the case of traveling the curved part.

摘要： PROBLEM TO BE SOLVED: To provide a body structure capable of reducing man-hours for manufacturing and structuring with a small number of parts. SOLUTION: A roof body structure 1 comprises an outside plate 10, a cantrail 20 and a common rafter 30. In the roof body structure 1, the common rafter 30 is jointed to the cantrail 20 in a manner that the common rafter 30 is piled on the cantrail 20. Thus, in the case where no discontinuing part is provided at a crossing part of the cantrail 20 with the common rafter 30, to optimize bending rigidity, it is not necessary to provide a tipped part at the part of the common rafter 30 for extending the cantrail 20 passing through it, hence the man-hour for manufacturing can be reduced. The common rafter 30 has a section area formed with a panel material bent as a wave form so that the common rafter 30 is not likely affected by falling deformation when a load in an X direction is applied. Thus, a clip member for preventing the common rafter 30 from falling down can be omitted and the number of parts can be decreased.

摘要： PURPOSE:To provide the magnetic shielding structure for magnetic levitating railway rolling stock, which sufficiently prevent the generation of leak of magnetic flux inside of a vehicle connection part. CONSTITUTION:Connecting frame parts 11, 21 provided at the ends of magnetic levitating railway rolling stock are formed into a nearly rectangular frame shape by extending through-paths 13, 23 of passenger rooms. The lower-half of the frame parts 11, 21 are shield parts 11a, 21a formed by magnetic shield plates. Gangway footplates 12, 22 contact with each other and overlapped with each other. As a result, the fore and aft directional magnetic path, which is formed of the shield part 11a, the gangway footplate 12, the gangway footplate 22 and the shield part 21a, is formed in the connection part 28 of the vehicles. The path 33 inside of the connection part 28 is thereby magnetically shielded. This magnetic path is not cut on the way and continuously formed even in the case where a relative displacement is generated between the vehicles 10, 20, and the magnetic shielding effect of the through-path 33 inside of the connection part 28 is maintained.

摘要： PURPOSE:To prevent the interior of a car from being warmed by the discharged head of the installed equipment and reduce the weight of a car body. CONSTITUTION:During the traveling of a high speed vehicle, an air taking inlet 4 for stop time is closed, and outside air (cooling air) is taken into a car from an air taking inlet 1 by the ram pressure. At this time, air is directly introduced into the equipment from the upstream side opened port part of cooling part for the installed equipment 2a-2c, by the pressure difference between the upper part A of the car inside and the outside B of the lower part of a car body, and the air after cooling is directly discharged outside the car body through air discharged flow passages 3a-3c separated for the car room from the downstream side of the cooling part. When the high speed vehicle is in stop, the taking inlet 4 is opened, and a fan 5 is driven to take in the outside air (cooling air) inside the car. Also in this case, air is directly introduced into the equipment from the upstream side opened port part of the cooling part for the installed equipment 2a-2c, by the pressure difference between the upper part A of the car inside and the outside B of the lower part of the car body, and the cooling air after cooling is directly discharged outside the car body through air discharge flow passages 3a-3c separated for the car room from the downstream side of the cooling part.
