About this book

This book provides a discussion on the results of studies the author was conducting for several years, addressing the impact exerted by operating parameters of the engine and the power transmission system as well as the vehicle’s technical condition and service factors of the suspension system components on the vibrations being generated. The author proposed specific methods dedicated to identification of the vibration structure in the function of time, frequency and time-frequency distributions, compared characteristics of the vibration structure of wave propagation in three orthogonal axes as well as identified the vibration distribution in a vehicle structure. Ultimately, such a wide range of experimental studies and analyses enables accurate assessment of the human exposure to vibrations in means of transport based on multidimensional analysis of the vibration exposure time for successive frequency bands. It may also initiate a new approach to experimental modelling and identification of the oscillatory wave propagation in a vehicle structure.
