الملخص
The frequency-locking area of harmonic and subharmonic ( 1/2,1/3) solutions in a fast harmonic
excitation Mathieu-Van der PolDuffing equation is studied. A perturbation technique is then
performed on the slow dynamic near the harmonic and subharmonic ( 1/2, 1/3) solutions, to obtain
reduced slow flow equations governing the modulation of amplitude and phase of the corresponding
slow dynamics. Results show that fast harmonic excitation can change the nonlinear characteristic
spring behavior from softening to hardening and causes the entrainment regions to shift. Numerical
solutions are represented the analytical results.
