Popov I.P.


The purpose of the study is to detail the types of mechanical power for harmonic oscillations. It is shown that during mechanical vibrations, not only a sign-positive thermal power develops, but also sign-alternating reactive powers, which characterize the reversibility of the kinetic and potential energies. Active power is understood as the average value of instantaneous power over half a period, and reactive power is the amplitude value. The total mechanical power, on the one hand, is described by the Pythagorean formula, and on the other hand, it is equal to the product of the effective values of the harmonic quantities. A feature of the complex representation is that when calculating the total power, one of the multiplied vectors must be conjugate.
