Influence of transportation object position in car body on its vibrational loading

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
