Applied Physics and Mathematics Annotation << Back APPLICATION OF SYMBOLIC (COMPLEX) METHOD FOR CALCULATION OF COMPLICATED MECHANICAL SYSTEMS UNDER HARMONIC EXPOSURE I.P. POPOV The representation of harmonic quantities in the form of rotating vectors in the complex plane and the operation with their complex amplitudes makes it possible to repeatedly simplify the calculation of arbitrarily complex mechanical systems with harmonic effects in the steady state. A series of relevant theorems is proved. Keywords: Reactance, Resistance, Impedance, Sasseptance, Conductance, Admittance. DOI: 10.25791/pfim.04.2019.828 Contacts: - Pp. 14-24.
