ABSTRACT:
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.
