The dynamic behaviors of a delaycoupled ring of van der PolDuffing oscillators were studied. The stability and bifurcation of the system were determined by solving the associated characteristic equation. The parametrical regions of amplitude death were shown in the plane of time delay and coupling strength. Case studies were carried out by numerical simulations, which were validated by circuit experiments. It was shown that time delay can give rise to abundant and interesting behaviors, such as amplitude death, different periodic oscillations, quasiperiodic responses, and even chaotic attractors.
