Abstract
The problems of studying the static lateral stability of machine-tractor units by the methods of multi-body dynamics (MBD) are considered. To create a simulation model, the virtual modeling method in CAD SolidWorks and CAE SolidWorks Motion was used. A 3d model of the MTZ-82.1 tractor was created, equipped with front and rear mounted three-point linkage. At the same time, all the basic structural elements and their geometric and mass-inertial parameters were preserved. The tractor was aggregated with front and rear mounted modular implements. To study the lateral stability, the tractor is mounted on a virtual stand consisting of a fixed base and a platform that changes the angle of inclination. Using a virtual stand, the lateral stability angles of three typical configurations of a machine-tractor unit and a tractor without attachments were obtained. For a tractor without attachments, the rollover angle was 34°, it was equipped with a single-beam rear mounted implement 36° (scheme 0 + 1), with a double-beam rear mounted implement 25° (scheme 0 + 2), with a front mounted implement and a double-beam rear mounted implement 36° (scheme 1 + 2). Verification of simulation data was carried out by comparing with experimental data obtained at a stationary stand. The difference in the values of the critical angles of lateral stability of the tractor, obtained by the results of virtual modeling and using the method of rollover the tractor on a stationary stand, is 3 … 5°.
