This paper investigates a physical model of the wheel traction in the relationship of the motion dynamics, and thereby studies the cases where a rover negotiates with natural rough terrain, slips and stacks on a steep slope. Experiments are carried out with a rover test bed to observe the physical phenomena and extract essential parameters, and the dynamic simulations are carried out to be comp...
The article is devoted to the development of a mathematical model an industrial tractor with semi – rigid suspension. intended for computational study vibrations at driver's seat caused by low frequency impact from caterpillar mover. A review wel l–known models describing dynamics system “soil mover body cabin vibration protection driver” made. Various methods soil modeling and caterpillars are...
The superconducting magnetically levitated transport (Maglev) system is conceptualized as a next-generation high-speed transportation system. For practical use, it is important to achieve adequate ride comfort particularly in high-speed running. Maglev vehicles are composed of lightweight car bodies and relatively heavy bogies which are mounted with devices such as superconducting magnets (SCMs...
Rovers will continue to play an important role in planetary exploration. Plans include the use of the rocker-bogie rover configuration. Here, models of the mechanics of this configuration are presented. Methods for solving the inverse kinematics of the system and quasi-static force analysis are described. Also described is a simulation based on the models of the rover’s performance. Experimenta...
When railway vehicles run on sharp curves, the coefficient of friction (COF) between outer rail and leading-outside wheel flange a bogie is an important value related to problems such as wheel/rail severe wear, squeak noise arising from contact, running safety against flange-climb derailment. In general, it difficult grasp actual state COF, which changes moment during commercial operations. Fro...
Purpose. The work is aimed at determining the influence of lateral displacement a freight car bogie, taking into account value movement speed on its main dynamic indicators and interaction rolling stock track. Methodology. quantitative assessment was obtained by method mathematical computer modeling. design scheme takes peculiarities cars as part train: possibility all modes body vibration in s...
Railways as a dimension of transportation infrastructure has been widely welcomed in developed and developing industrial countries because of the ability to carry heavy loads over long distances, more safety, less depreciation, less cost, less pollution, etc. Therefore, knowledge of the dynamic behavior of the railway is essential for designers and builders. It is very important to study the vi...
