Embodiment Construction

[0039] Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.

[0040] Before explaining the specific structure in which the present invention is applied to an actual vehicle body, first, the results of a simulation performed on a model with a simplified structure will be described.

[0041] figure 1 (a) represents the rigid binding model A used for this simulation, figure 1 (b) represents the combination of rigid bonding and flexible bonding Model B. Such as figure 1 As shown in (a) and (b), in any model of rigid bonded model A and rigid bonded and flexible bonded model B, the first part 1, the third part 7, and the plate-shaped cap-shaped section are used. The second member 2 is used as a vehicle body structural member, and the hollow frame 4 extending in the longitudinal direction is formed by joining the second member 2 on one surface of the first member 1 and the third member 7 .

[0042] Both the first member 1 and ...

Abstract

In a vehicle-body structure of a vehicle which comprises vehicle-body forming members forming a closed-section portion and having a dent portion which dents toward an inside of the closed-section portion, and a reinforcing member provided in the closed-section portion and joined to the vehicle-body forming members, a joint portion of the vehicle-body forming members and the reinforcing member includes a rigid joint portion where the vehicle-body forming members and the reinforcing member are joined with a direct contact thereof and a flexible joint portion where the vehicle-body forming members and the reinforcing member are joined via a damping member provided therebetween, and this joint portion is provided at or in the vicinity of the dent portion.

Description

technical field [0001] The invention relates to a vehicle body structure and a manufacturing method thereof. Background technique [0002] In vehicles such as automobiles, it is necessary to increase the rigidity of the vehicle body in order to improve ride comfort and safety. As a technology for increasing rigidity, for example, Japanese Patent Laid-Open Publication No. 59-182472 (hereinafter referred to as Patent Document 1) and Japanese Patent Laid-Open Publication No. Sho 60-097673 (hereinafter referred to as Patent Document 2) discloses a technique of providing a reinforcing body in a closed cross-sectional portion formed by structural members of a vehicle body. [0003] Patent Document 1 discloses a structure in which a bulkhead is provided in a nodular shape in a closed section of a side sill formed by a side sill outer and a side sill inner, and a flange provided around the bulkhead is welded to the The adhesive is bonded to inner surfaces of the side sill outer and...
