Nonlinear vibration mitigation of a crane’s payload using pendulum absorber

The paper proposes and investigates nonlinear vibrations mitigation strategies of an externally excited pendulum. This problem is highly relevant to the crane’s payload behavior, which dynamics typically described by a pendulum model. Currently, there are various active control mitigate swinging that require some knowledge on state, but, authors’ best knowledge, no passive measures such vibrations. proposed involve utilization another pendulum, adjustable mass length can tune characteristics reduce payload. obtained results for system have identified optimal configuration absorber appropriate set parameters, allow reducing payload’s amplitude more than five times.
