The article considers the features of the dynamics of systems with several degrees of freedom with the introduction of additional constraints. As an example, the authors consider the computational scheme of a locomotive traction engine with an axial overhung support. Different cases of the combination of perturbations were analyzed and the conditions for dynamic damping were determined. The specificity of the tasks to be solved was in the necessity to determine the conditions while choosing system parameters that would minimize the occurrence of cross-couplings. These conditions were determined and implemented through the introduction of additional inertial elements into the system structure. With an appropriate choice of system parameters, the vibration platform can be invariant with respect to the deviation to the kinematic effect xj(t). The necessary conditions that can be obtained by parallel inclusion of inertial and elastic elements in systems with low friction were considered.
