An under body structure of an automobile enabling batteries to be mounted on an automobile by a simple configuration and efficiently transferring load at the time of a collision, that is, an under body structureof an automobile provided with a body floorforming a floor part of the automobile and batteries(battery cells or battery modules) directly suspended from and fastened to a bottom side of the body floor

Under body structure of automobile

A lateral surface member structure () of a vehicle body () includes a tubular body () extending in a front-rear direction of the vehicle body () and an impact absorbing member () disposed inside the tubular body (). The impact absorbing member () includes a web () extending along the front-rear direction and flat in a vehicle width direction, a vehicle outer flange () joined to a vehicle outer end portion of the web () and extending along the front-rear direction, and a vehicle inner flange () joined to a vehicle inner end portion of the web () and extending along the front-rear direction. The vehicle outer flange () and the vehicle inner flange () each include a rib (R,R) disposed so as to sandwich the web () from above and below and extending along the front-rear direction.

Lateral surface member structure of vehicle body

A test sample support for use in a collision test using a center pillar assembly of an automobile body as a test sample, includes a linear main body, a first attachment part, and a second attachment part. A cross section of the main body of the test sample support is an open section of cross-shaped. The first attachment part is secured to the center pillar assembly. The second attachment part is secured to a collision test apparatus. This makes it possible to perform a collision test conveniently and at a low cost, thereby accurately evaluating side collision performance of the center pillar assembly.

Collision test apparatus using test sample support for structural member

A steel sheet member combination structure includes: a first steel sheet member having a main wall portion, a standing wall portion that stands from an end edge of the main wall portion, and a flange portion that extends parallel to the main wall portion from an end edge of the standing wall portion; and a second steel sheet member having a horizontal wall portion that is joined to at least one of an inner surface or an outer surface of the first steel sheet member and that abuts the main wall portion and a side wall portion that abuts the standing wall portion, and the first steel sheet member and the second steel sheet member satisfy predetermined relational expressions.

A movable member is gripped in a delamination-start configuration, and the other-end side of a rib of a delamination member is pressed towards the other-end side of a flexible plate. The flexible plate then warps and deforms about the other end side of the flexible plate, which is supported by a support member, the flexible plate deforming along the direction in which delamination progresses. In concert with the delamination action, a reinforcing plate also warps and deforms along with the flexible plate, the reinforcing plate being vacuum-chucked to an air-permeable electroconductive sheet on the flexible plate, and the reinforcing plate is sequentially delaminated from a substratealong the direction in which delamination progresses.
