Abstract
Measurement of vibration of the vehicle on the road surface is one of the key elements of cargo and vehicle security. This paper provides results from transporting military cargo study that analyzed the various vibrations of acceleration during transport on a stony pavement road. The data include vibrations from three directions: longitudinal, transverse and vertical. Based on collected data the quantitative analysis of vibrations was conducted. The peak acceleration as well as the acceleration level was identified. The growth rate acceleration affecting the smoothness of driving and the impact of the vehicle on the stony surface were calculated. The study shows that the greatest impact on transporting cargo have vertical vibrations. In addition, using the Fourier transform, amplitude spectrum for all directions of oscillation was assigned.

The growth acceleration is a kinematic parameter occurring in geometric systems that affect the smoothness and dynamic effects of the vehicle on the road surface
Summary
To demonstrate the effect of vibration on the means of transport and cargo, methods of spectral analysis [4] are used. They are transforming time series of observed accelerations into frequency domain which is efficient for analyzing frequency characteristics of vibrations, in particular, for determining the amplitude. It’s important parameter which is a nonnegative number that specifies the stroke size of the periodic function, indicating the largest deviation from the equilibrium position [5] Based on this assumption, it can be concluded which vibration is subjected to the load during transportation
