Simulation of dynamics of industrial tractor under low-frequency vibro-excitation from the tracked mover.

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 considered. It proposed use ANSYS Motion software package simulate subsystem "soil track rollers bogie". describes in detail undercarriage system, taking into account actual geometry tracks, arrangement rollers, as well other design features. To describe deformation package, used relations Becker Wong. presents results tracked bogie T–130 Chelyabinsk Tractor Plant when moving on deformable soil. Calculations were made three types different locations road wheels. processes vertical angular displacements obtained. An analysis calculation showed that reveals influence properties running tractor. obtained result simulation will be input “tractor cab driver”. studies optimizing operator. Recommendations developed change wheels elastic–damping characteristics elements minimize operator
