Applied Physics and Mathematics Annotation << Back DIFFERENTIAL EQUATIONS OF TWO MECHANICAL RESONANCES I.P. POPOV The definitions of resonances of forces and velocities are given. It is shown that with a parallel connection of an inert body, an elastic element and a damper in the system, a resonance of forces may occur. When these elements are connected in series, a velocity resonance may occur. Classic mechanical resonance is a resonance of forces. Anti-resonance is velocity resonance. Keywords: resonance of forces, velocities, parallel connection, series, source of force, speed. DOI: 10.25791/pfim.02.2019.599 Contacts: E-mail: ip.popow@yandex.ru Pp. 37-40.
