Study of the Influence of the Relative Rigidity of an Elastic Hybrid System Without Damping, on Natural Self-Pulsation, Amplitude and Dynamic Factor Due to Forced Vibration

Abstract The paper aims to study the dynamic behavior of a hybrid elastic system without damping consisting of a beam in a cantilever supported on helical compression springs on which an electric motor is mounted. With the help of the MATHCAD professional program, the influence of the relative stiffness of the elastic bar subjected to bending and the springs subjected to compression was simulated, on the natural pulsation, the amplitude of the vibrations and the dynamic factor of the forced vibrations for two assembly variants of the electric motor
