Strutynskyi Serhii – doctor of technical sciences, docent of the Department of Applied Hydroaeromechanics and Mechanotronics of the National technical University of Ukraine “Igor Sikorsky Kyiv Polytechnic Institute”, (pr. Peremgy, 37, Kiev, Ukraine, 03056, e-mail: strutynskyi@gmail.com).


The results of investigations of dynamic wave processes in a caterpillar mover of a terrestrial robotic complex are presented. For this purpose, the theoretical model of the dynamics of caterpillar mover is substantiated. The model takes into account the occurrence of dynamic pulsed loads in the caterpillar mover drive. The loads are described by a random process through random amplitude periodic impulses. The dynamic caterpillar system is presented as a huge infinite tension thread grounded on an elastic and strain basis.

The statistical characteristics of random loads in the caterpillar mover drive are determined. Spectral density of loads is found as a superposition of a continuous, fading with the growth of component frequency and pulsed resonance areas described by Gauss curves.

It is proved that pulsed loads in the drive and perturbation from the roadway cause the appearance of wave phenomena in the caterpillar through longitudinal waves propagated along the caterpillar causing its transverse oscillations. The energy dissipation in the caterpillar smoothes out the shape of the wave front and reduces the amplitude of oscillations. Recommendations for improving the dynamic characteristics of a caterpillar mover in particular by using oscillation inertial damping, have been developed.


Keywords: mobile robot, chassis, dynamics, pulsed loads, spectrum, caterpillar, longitudinal waves, mathematical model, periodic oscillations

History of journal:

In June 1994 the 2nd International Scientific and Technical Conference "Application of vibrations for technological purposes" was organized on the basis of Vinnytsia State Agricultural Institute. Leading experts in this field, noting the significant contribution to the school of Vibration Engineering under the leadership of P. S. Bernyk, proposed to create a professional all-Ukrainian scientific and technical journal "Vibration in engineering and technology..The journal was foundedat Vinnytsia State Agricultural Institute and P.S. Bernyk was elected to be the chief editor .
For all these years (since 1994) theJournal "vibration in engineering and technology" published  94 issues wherestudy of vibration effects, the creation of progressive energy saving technologies and equipment for their implementation were highlighted.
Currently Kaletnik H.M  PhD , professor, academician NAAS is the chief editor of the "Vibrations in engineering  and Technology"
The journal "Vibration in Engineering and technology", which has no analogues on the territory of Ukraine, is well known abroad.
