Оценка плавности хода гусеничной машины при использовании дополнительных демпфирующих устройств

Abstract

The problem of estimating the smooth running of a caterpillar vehicle using additional damping devices is considered. Increasing the requirements for mobility and, in particular, for the smooth running of high-speed crawler vehicles led to the need to increase the energy intensity of the suspension system. One way to improve ride smoothness and reduce overheating of hydraulic shock absorbers is to install additional damping devices that act at the end of the dynamic stroke of the roller, working in conjunction with the main shock absorber. This makes it possible to reduce the absorbed power of the damping devices in all modes of the machine's motion, provided that the necessary smoothness of the stroke is maintained. The article presents the speed characteristics of a modernized suspension system, obtained as a result of mathematical modeling. The obtained results are evaluated in comparison with the initial characteristics. The estimation of the level of power absorbed by the main and additional damping elements during movement along irregularities is given.
