Abstract
Dynamic model for research of object transportation location influence on its
vibrating loading by moving through a number of single obstacles, road with random microprofile
and rough road is offered. Differential equations and methods of their integration in MATLAB
Simulink software product are presented. The values of frequencies and amplitudes of vertical
oscillations, vibration acceleration of the transportation object at different locations in the vehicle
body were obtained. It is found that the amplitude and maximum acceleration have the smallest
values when the object is located in the center of gravity of the car, and the largest – above the rear
axle (in the cargo compartment). Recommendations were to improve the vibration protection of the
transportation object.
