DETERMINATION OF STATIONARY VIBRATIONS OF A LINEAR CONSERVATIVE SYSTEM WITH TWO DEGREES OF FREEDOM. Part 1. GENERAL PERIODIC DISTURBANCE
Forced vibrations of a linear undamped two-mass system connected in series are considered. It is assumed that the exciting loads are general periodic functions satisfying the Dirichlet conditions. Applying functions of the system response resulting from the application of the unit step load, the exact closed-form solution of vibrations of the system with the period of excitation is obtained. As examples, the vibrations of the system under harmonic and «saw tooth» loads are found.
