DISSIPATIVE OSCILLATORS’ POWER CHARACTERISTIC NON-SYMMETRY DYNAMIC EFFECT

The features of motion a non-linear oscillator under the instantaneous force pulse loading are studied. elastic characteristic is given by polygonal chain consisting two linear segments. focus paper on influence dissipative forces possibility occurrence non-symmetry dynamic effect, studied previously without taking into account these forces. Four types drag considered, namely viscous friction, Coulomb dry position and quadratic resistance. For cases friction analytical solutions differential equation oscillations found fitting method formulae for computing swings derived. conditions parameters problem determined which effect occurs in system. to occur system with derived from energy relations solving motion. In case first integral Lambert function either positive or negative argument depending value initial velocity. shown small velocities, whereas it absent when velocities sufficiently large. values proposed be computed interpolation known data approximation elementary functions using asymptotic error less than 1%. theoretical study presented followed up computational examples. results computations perfect agreement numerical integration computer.
