Off-design loading modes of the road rollers of the undercarriage of the tracked vehicle

This paper examines the results of a research of off-design loading modes of road rollers of tracked vehicles. An additional load is formed by parametric resonant oscillations of the road rollers that arise when driving on a low-deformable support surface. To solve the problem of eliminating resonant oscillations, a mathematical model of a dynamic system is being developed, and also experimental studies are being carried out. Technical solutions are substantiated to reduce the dynamic loading of the road wheels on the basis of increasing the dynamic stability of the periodic solution by reducing the modulation depth of the elastic interaction of the road wheel with a rubberized treadmill.
