摘要： The present invention is a floor panel structure of a car body where an automobile floor includes a floor panel that is connected to the frame members of the car body and also have a vibration mode adjusting structure that suppresses the generation of acoustic emission by generating 2×1 mode vibrations in a predetermined frequency band. The floor panel has a non-rectangular vibration region and the vibration mode adjusting structure of the floor panel has a vibration adjusting part that defines the position of node of 2×1 mode vibration, and this vibration adjusting part is disposed within the non-rectangular vibration region so as not to touch the frame members and so as to form two regions where the vibration volumes of two antinodes of vibration in 2×1 mode are made nearly the same.

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.
