Optimizing the dynamical behavior of a dual frequency parametric amplifier with quadratic and cubic nonlinearities

Amit Dolev, Izhak Bucher

The paper describes a novel parametric excitation scheme that acts as a tunable amplifier by controlling two pumping signals and two nonlinear feedback terms. By modulating the sti…

Dynamic balancing of super-critical rotating structures using slow-speed data via parametric excitation

Shachar Tresser, Amit Dolev, Izhak Bucher

High-speed machinery is often designed to pass several critical speeds, where vibration levels can be very high. To reduce vibrations, rotors usually undergo a mass balancing…
