COMPARATIVE ANALYSIS OF NONLINEAR RESONANCES OF A MECHANICAL SYSTEM WITH UNSYMMETRICAL PIECEWISE CHARACTERISTIC OF RESTORING FORCE

摘要

We present results of a numerical comparative analysis of superharmonic resonances of the order 2/1-1/5 and subharmonic resonance of the order 1/2 of a mechanical single degree-of-freedom vibrating system with unsymmetrical characteristic of restoring force at different ratios of system rigidities in half-cycles and under the conditions of considerable change in vibration damping level in the system.
