• Theoretical analysis is presented for the dynamic behavior of a wave energy converter which has oscillating two-dimensional cylinders and absorbs power in an incident sinusoidal wave train. The energy converter is an array of two or more than two bodies connected by rigid links. By taking into consideration of the interactions of waves between the floating bodies, dynamic equations of a floating system with inertial, restoring and damping forces are derived using velocity potentials assuming a linear theory. Rate of energy absorption when each body in the array oscillates in two modes is obtained. It is shown that nearly 100% efficiency is available under the approximate tuning condition when three or four oscillating bodies are used and also that the band width of energy absorption efficiency will be largely widened compared with the conventional single body energy converter. These characteristics are of great practical value seeing the changeable nature of ocean waves.
