    摘要: An automotive frame part is provided to a side portion of an automotive body and absorbs crashworthiness energy by bending upon receiving a crashworthiness load from a side of the automotive body. The automotive frame part includes: a member having a hat-shaped cross section or a U-shaped cross section and including a top portion, and a pair of side wall portions that are continuous from the top portion via punch shoulder R portions; and resin that is coated on or patched to an internal surface of the member having the hat-shaped cross section member or the U-shaped cross section. The resin extends at least to a predetermined range toward the top portion and the side wall portions on both sides of the punch shoulder R portions, and is adhered, after heating, to the internal surface at an adhesive strength of 10 MPa or higher at a room temperature.

    摘要: A side crash test apparatus uses a crash test structure including a center pillar, a roof-rail simulated part, and a rocker simulated part, and includes: a striker; a roof rail support; and a rocker support. The rocker support includes a rocker-rotation braking mechanism configured to restrain translation of the rocker simulated part, and support the rocker simulated part to be rotatable about an axis thereof and allow braking of the rotation. The rocker-rotation braking mechanism includes a rocker-rotation support member configured to rotate about the axis together with the rocker simulated part, a rocker-rotation shaft support configured to support a rotation center of the rocker-rotation support member, a rocker-rotation braking plate extended by rotation of the rocker-rotation support member while braking the rotation when the striker crashes into the center pillar, and a rocker rotation braking plate fixed portion configured to fix another end side of the rocker-rotation braking plate.
