Title: Reinforcement arrangement method for panel structure
Inventor: HACHIMAN JUTARO
IPC: E02F9/16
Filed: 1999-12-16
Abstract: PROBLEM TO BE SOLVED: To secure tensile rigidity and to optimize gross weight when installing a reinforcement to a panel structure to secure the tensile rigidity in the case that a panel single body has the weak tensile rigidity, e.g. a door panel of a truck, by setting optimum arrangement of the reinforcement and optimum structural items of the panel structure and the reinforcement. SOLUTION: In a truck door 1, the reinforcement 8 is bonded to the inner face of the outer panel 2 to secure the tensile rigidity. In the case that a load sequentially increasing from zero is applied to a load point of the outer panel 2 set to the center between the reinforcement 8 and a door frame 6, analysis of the rigidity in initial stages of the increase shows that the initial rigidity is decided according to the arrangement of the reinforcement 8. Accordingly, as the optimum arrangement, it is preferable that the reinforcement 8 is horizontally arranged. Analysis of load share of the outer panel 2 and the reinforcement 8 accompanying the increase of the load shows that a load share rate of the reinforcement 8 is larger than a weight ratio of the reinforcement 8 in a large deformation amount region.  Accordingly, both the securing of the rigidity and reduction of the gross weight of the whole truck door 1a can be simultaneously realized by reducing a plate thickness of the outer panel 2 to lighten the panel 2 and increasing a plate thickness of the reinforcement 8 to increase the rigidity of the reinforcement 8.
