摘要: Abstract A combined analysis method is developed in the present paper for studying dynamic properties of a type geometrically nonlinear vibration isolator, which composed push–pull configuration rings. This combines theory curved beams and Harmonic Balance Method to overcome difficulty calculating transmissibility under large deformations ring structure. Using proposed method, behaviors this such as lock situation due coulomb damping usual jump resulting from stiffness, can be investigated. Numerical solutions based on primary harmonic balance are first verified by direct integration results. Then, whole procedure demonstrated validated slowly sinusoidal sweeping experiments with different amplitudes base excitation. Both numerical experimental results indicate that isolator behaves hardening spring increasing amplitude excitation, makes it suitable isolating both steady-state vibrations transient shocks.
