Resonant vibrations of the sprung part of the military tracked vehicles with non-linear characteristics of suspension

A research method for track rim bending vibrations affected by transient perturbations in military tracked vehicles has been proposed. It was based on the assumption that perturbation is presented by analytical function and combination of the perturbation and Van der Paul. Dependencies which describe the dynamics of tracked rim for resonant and non-resonant cases have been obtained. It methods has been established that resonant value of amplitude is defined by the vehicle’s speed and characteristics of non-linear suspension. The condition for the non resonant movement along ordered barrier system has been obtained.
