摘要： PURPOSE:To make the strength of one-side welded joints equal to that of the case of both-side welding, considerably reduce the number of manufacturing steps and achieve rationalization of work by providing notches partially to the specified bonding portions of the ends of main members at the time of welding frameworks of sheets to themselves. CONSTITUTION:At the time of welding the main member 1 of the framework and a sheet sub-member 2, notches 9 are provided at the bonding portions of the flange 3 and web 4 of the end part of the main member 1 of larger load distribution and welding from one side of the members with the crack-producing part of the joint is performed from one side. In this way, the weld zone 8' similar to that when welding 8 from the other side done is produced and the end face is surely fusion-welded. As a result, the number os welding steps may be reduced to 1/2 that of both-side welding. This method is particularly effective when welding from the other side is infeasible.

摘要： PROBLEM TO BE SOLVED: To provide a safe rail rolling stock which absorbs impact energy.
SOLUTION: A front unit 100 is located at a front end of a car body. Its floor comprises a hollow member 210 consisting of a buffer unit 200. The buffer unit comprises an upper and a lower buffer unit 200, 200. An annealed hollow member is used for the hollow member 210. A pushing-out direction of the hollow member 210 is a longitudinal direction of the car body. The longitudinal direction of the hollow member 210 is partitioned into two parts with a plate 220. Face plates 211, 212 of the both surfaces of the width direction of the hollow part 210 are jointed with plates 223 to 226. When the impact load is applied, the hollow member 210 is deformed into a bellows shape and absorbs impact force. Since the longitudinal direction of the hollow member 210 is partitioned with the plate 210, it is not buckled into a dogleg shape, and continuously buckled into a bellows shape to absorb a large amount of energy.

摘要： PROBLEM TO BE SOLVED: To provide a body of rolling stock retaining a shock-absorbing structure part inside it within a range outstandingly not-exceeding a size of the structural member without adding particular members to the inside of the body or a lower part of the floor in the body constituted of a hollow extrusion material. SOLUTION: In the body of the rolling stock composed of a hollow material 40, a hollow material 51 having a shock-absorbing function is provided on the hollow material 40 at an end part of a base frame 30 having a high possibility receiving a collision load. The hollow material 40 makes the longitudinal direction thereof as the longitudinal direction of the body. When the collision load is applied thereto, a part of the hollow material 51 is deformed and ruptured to absorb an impact force. An impact force to passengers is relaxed as small as possible at the time of collision of a train only by machining a part of the hollow material without totally varying the present body structure and a safety can be enhanced.

摘要： PROBLEM TO BE SOLVED: To closely form a joint surface in a close contact state following the surface shape and irregularities of a structure by laying a soft insulating material on an outermost layer and a heat insulating material of higher rigidity inside the soft insulating material. SOLUTION: A locally deformable soft insulating material 3 is attached to the interior surface of a structure 4 via an adhesive, so as to keep the whole surface of the material 3 in contact with the surface of the structure 4. Also, plate type heat insulating materials 3a, 2b and 2c divided into a plurality are arranged on the interior surface of the soft heat insulating material 3 via an adhesive, so as to be adjacent to one another. In this case, a material harder than the soft heat insulating material 3, but having a better function as a heat insulating material in terms of heat conductivity or the like is selected as the heat insulating material 2. Furthermore, the plate type heat insulating material 2 is attached to such an extent as partly deforming the soft heat insulating material 3, so as to come in contact therewith over entire surface. According to this construction, the composite heat insulating material 1 so formed can be laid on the surface of the structure 4, even when irregularities exist thereon.

摘要： PROBLEM TO BE SOLVED: To materialize weight reduction, improvement of pressure resistance, and silencing of compartments, by constituting a structure of a stacked material, where surface material made of a light alloy, core material, and member for coupling are joined with one another by brazing, and a damping material which has heat insulation and arranging the damping material installed on the side of compartments capably of removal. SOLUTION: A structure is constituted of an underframe, a side structure, a roof structure, and an end structure. At the side structure, the side outer plate 6 is stacked material which comprises a surface material 7 made of light alloy, a core material 8, and a coupling material 8, and which is made by arranging surface materials 7 to both sides of the core material 8, and besides, arranging members 9 for coupling at the peripheral ends of the core material 8 both surface materials 7 and between both the surface materials 7, and joining these by brazing. For the core material 8, a honeycomb material made of light alloy is used. A damping material 10 which has heat insulating effect is joined to the side of compartments of the side outer plate 6 capable of partial removal. The joining of the damping material 10 and the side outer plate 6 is performed using an adhesive 11 excluding the section 10a capable of removal. As a result, the weight reduction, improvement of pressure resistance, and silencing of compartments can be materialized.
