Abstract

L.M. Petrov, Y.M. Petryk, G.B. Shishkin. The working process of rolling a wheeled engine is accompanied by the loading of the wheeled engine by the force of gravitational load, which leads to compression and stretching of the tire during its deformation. The article considers the issues of studying the mechanical system "automobile wheel-spring compensator of traction force", using the theorem on the change of kinetic and potential energy in a combined wheeled engine, the general equation of dynamics, and the Lagrange equation of the second kind.

This scientific work highlights the development and analysis of a combined wheeled engine for a military vehicle, which combines traditional wheel elements with spring and lever mechanisms.

A feature of the design is the ability to accumulate and effectively use potential energy arising from the action of gravitational force and spring deformation to provide additional movement of the vehicle. The constructed mathematical model allows quantitatively describing the change in the energy state of the system during movement, in particular, it takes into account the potential energy of the gravitational lever and springs, as well as the kinetic energy of the auxiliary wheels.

The dynamics of the engine operation in different phases was studied - from the equilibrium position to the extreme position with the maximum deviation of the elements. The presented equations allow determining the dependence of the total additional mechanical energy on the physical parameters of the structure and its current state. The analysis shows that in conditions of complex terrain, such a system can significantly increase the cross-country ability and maneuverability of the vehicle. The results have practical significance for further engineering development of specialized mobile platforms, in particular for military purposes, where energy efficiency and the ability to adaptively move are important.

The proposed theoretical provisions can be used to improve existing mechanisms of movement, as well as to create new types of energy-efficient engines, taking into account the limiting conditions of operation in field conditions. The article also provides a basis for conducting experimental studies to verify the predicted effects and improve the mathematical models presented in the paper.

Keywords: combined engine, military vehicle, kinetic energy, potential energy, gravitational lever, spring system, cross-country ability, mathematical modeling, energy balance, adaptive movement.
