摘要： A floor panel structure of a vehicle body where a vehicle floor has floor panels with their peripheral edges linked to a plurality of frame members that are disposed in a vehicle body lengthwise direction and a vehicle body crosswise direction and linked to an engine or a suspension is disclosed. The floor panel has a joint where at least part of its peripheral edge is joined to the frame member, a groove formed along the entire length of the joint and a high-rigidity area formed within the low-rigidity area. The low-rigidity area forms a vibration blocking area along the entire length of the joint by using a difference in rigidity from the high-rigidity area.

摘要： Disclosed is a floor panel structure for an automobile body, which comprises a floor panel (2, 4, 6, 12) joined to a plurality of frame members (22, 24, 27 to 32, etc.) extending in longitudinal and lateral directions of the automobile body so as to make up an automobile floor. At least a part of the floor panel has a panel zone (S1, S2, S4, S5, S6, S8) surrounded by the frame members. The panel zone includes a high-rigid portion (84) formed by deforming a central region thereof to protrude upward or downward, and a low-rigid portion (86) formed around the high-rigid portion. The high-rigid portion is formed with a concavoconvex element, such as a bead (90). The floor panel structure of the present invention can effectively reduce vibrational energy of a floor panel so as to reduce acoustic radiation from the floor panel.

摘要： The present invention is a floor panel structure of a car body that can reduce noise within the automobile cabin. The present invention is a car body floor panel structure wherein the floor of an automobile has a floor panel connected to car body frame members, and also a predetermined mode of vibration is generated to suppress the generation of acoustic emission from the floor panel. The floor panel vibration mode adjusting structure has rectangular rigidity adjusting areas that are formed by causing the floor panel to protrude upward or downward in order to generate 2×1 mode or 2×2 mode vibration in the floor panel in a frequency band that nearly matches the tire cavity resonance frequency.

摘要： A floor is partitioned into a plurality of areas S1 to S4 by a floor tunnel portion 11, side frames 13, side sills 12, and cross members 7, 8, 15, and 16, and the rigidity of the floor panels of the areas S1 to S3 is adjusted by rigidity adjustment portions 20, 21, 22, 23, and 25. These floor panels are set such that their natural frequency in a 2×1 mode, in which two antinodes are generated in the length direction of the automobile and one antinode is generated in the width direction of the automobile, is 240 to 260 Hz. Thus, a reduction in road noise due to automobile tire cavity resonance is achieved.

摘要： The resin-made floor panel structure including a trunk floor F1 made of resin integrally forming a spare tire storage space S1, and a trunk board B1 made of resin disposed so as to cover the floor panel, fitting parts Sw1, Bk1 for achieving the closure of the spare tire storage space are integrally formed respectively in the trunk floor and trunk board. Thereby, in using resin materials for a floor panel, transmission of noise in the floor section to the compartment side can be suppressed by a relatively simple structure without increasing the weight.
