| Abstract [eng] |
The constructed third-order regression models demonstrated high adequacy (0.905 for stability and 0.987 for rotation moment), confirming their suitability for engineering applications. The results revealed pronounced nonlinear dependencies between the studied parameters and the coordinates of the lever attachment points. A geometric interpretation of the operability region showed that initial lever angles below 52° ensure a significantly wider range of feasible configurations, while larger angles reduce system operability. It was established that the upper attachment point coordinates have the greatest influence on both stability and actuation effort, whereas appropriate positioning of lower points can effectively reduce the required rotation moment. Further research should address dynamic vehicle– track interaction, include suspension and control system parameters, and provide experimental validation, with a focus on multi-objective optimization. |
