Summary
In order to study the noise transmission mode in a carbody of a high-speed train, this paper provides the analysis of the relationship of sound pressure level and vibration level in a plane sound wave. A laboratory test benchmark to evaluate the relationship is established. Concentrated force load and sound load have been used in the experiment. The "SPL-VL" formulas in every one-third octaves are found under the force load. The sound load test is used to evaluate the formulas. The results indicate that bending vibration is the main transmission mode of the noise in the special multilayer thin-wall carbody of high-speed trains. The data from operating trains validates this conclusion below 315 Hz.
