摘要： A carbody of a railcar includes: an underframe; a first member provided at one of vertical sides of a vertical center of the underframe, supported by the underframe, and absorbing collision energy; a second member provided at the other vertical side of the vertical center of the underframe, supported by the underframe, and contacting an obstacle when the first member is compressed by collision with the obstacle. In a case where the second member receives a reaction force from the obstacle when the first member is compressed by the collision with the obstacle, the second member transfers to the underframe a moment load that is opposite in a rotational direction to a moment load transferred to the underframe by the first member.

摘要： A collision energy absorbing device of a railcar includes: an outside plate constituting an outer tube including an axis extending in a car longitudinal direction; and at least one partition plate extending in the car longitudinal direction in an internal space surrounded by the outside plate, the at least one partition plate fixed to the outside plate and dividing the internal space. An outer shape of the outer tube is a shape that is symmetrical with respect to a virtual horizontal surface including the axis, and the at least one partition plate includes a missing portion in the internal space.

摘要： A carbody of a railcar includes an underframe, a side bodyshell, and a roof bodyshell. At least one of the underframe, the side bodyshell, and the roof bodyshell includes: an outer plate portion facing a car outside; and a reinforced portion joined to an inside surface of the outer plate portion and forming at least one internal space between the reinforced portion and the outer plate portion. At least one sound absorbing hole communicating with the internal space is formed on the outer plate portion.

摘要： A railcar head structure includes: a roof bodyshell positioned above a driver's cab window; and an underframe. The underframe includes: a pair of side sills; and a center sill located between the side sills and extending in a car longitudinal direction. A collision post is erected on a tip end of the center sill. A pillar is provided at the driver's cab window and extends so as to divide the driver's cab window. The pillar includes one end joined to the collision post and the other end joined to the roof bodyshell and couples the roof bodyshell and the collision post to each other.

摘要： A railcar collision energy absorbing device includes: an energy absorbing element crushed in collision; and a casing extending in a car longitudinal direction so as to accommodate the energy absorbing element. One end of the casing is supported by a main structure of a railcar. The casing is constituted by a plurality of tubular bodies whose overlapping portions are coupled to each other. The casing telescopically contracts in the collision by breaking of a coupling portion between the tubular bodies.
