Purpose: The article provides a discussion on the studies on material vibration propagation in floor pan of the passenger car. The purpose was to analyse the vibration signals in multiple measuring points. The time-frequency distribution of the signals allows to identification the dominant component of the signal useful for material natural frequency calculation. Design/methodology/approach: The investigations were conducted based on the modified method of experimental and operating modal analysis. The investigation comprised 3 steps: research and measurements of vibration accelerations in a vertical direction perpendicular to the horizontal surface of vehicle in four selected points (impact excitation), analysis of the time courses of the vibration response, signal processing and analysis of the time-frequency distribution of the vibration Findings: The distribution of the signal allows to identify the dominant frequency band. For the floor pan it is low frequencies, between 20 and 40 Hz. In this band the natural frequencies of the floor pan material can be identification Research limitations/implications: Number of the acceleration sensors and impossibility of the impact excitation signal recorded. Originality/value: Application of the modified method of experimental and operating modal analysis for the vehicle frame and car body. Research on the material properties influence on the vehicle vibration research. Comparison of the vibration structure at floor pan under the place of the driver and passengers feet as the vibration propagation path from frame and car body to the human body.
