Abstract
The paper studies the motion of transportation machine with packages on uneven road. Conditions of transportation that reduce the influence of harmful vibrations to the packages are determined. For this purpose the region was established where the slippage of packages with respect to the transported box of packages does not occur. The conditions for location of eigenfrequencies and forced frequencies are determined with the purpose to ensure that the system operates far from resonances. In order to avoid large overloads it is recommended to choose the velocity of motion in such a way, that the difference between the eigenfrequencies and the forced frequencies would be maxmin.
