Dynamic analysis of torsional discrete-continuous systems with position-dependent variable inertia
In the paper, dynamic investigations of multi-mass discrete-continuous systems torsionally deformed are performed taking into account the position-dependent mass moment of inertia of one of rigid bodies. It is assumed that the rigid body representing a motor moves with a variable velocity. An originally nonlinear problem is linearized; and the wave approach leading to solving equations with a retarded argument having variable coefficients is used for the solution. Exemplary numerical calculations are done for a three-mass system.
