Reducing the impact on small high-speed vessels is a challenge. This article proposes a wave-adaptive vessel (WAV) equipped with anti-impact semi-active electromagnetic suspension (ASES) to reduce the impact on the main hull. The electromagnetic suspension connecting the main hull and floating compartment is composed of a spring and an electromagnetic damper (EMD). The structure of the WAS is analyzed and introduced, and its dynamic model is established. An anti-impact controller that can fully utilize the suspension stroke is designed to calculate the ideal force for controlling the impact of the main hull. A semi-active control strategy is adopted to ensure that the actual output force of the ASAE can track the ideal force. Simulation analysis is conducted to validate the effectiveness of the proposed ASES. Simulation results show that compared to passive suspension, ASES can fully utilize the suspension’s travel to consume more energy during the main stages of impact, and the peak impact acceleration of ASES has been reduced by 42.25%. The proposed wave adaptive vessel equipped with electromagnetic suspension has practical application potential.

摘要

Reducing the impact on small high-speed vessels is a challenge. This article proposes a wave-adaptive vessel (WAV) equipped with anti-impact semi-active electromagnetic suspension (ASES) to reduce the impact on the main hull. The electromagnetic suspension connecting the main hull and floating compartment is composed of a spring and an electromagnetic damper (EMD). The structure of the WAS is analyzed and introduced, and its dynamic model is established. An anti-impact controller that can fully utilize the suspension stroke is designed to calculate the ideal force for controlling the impact of the main hull. A semi-active control strategy is adopted to ensure that the actual output force of the ASAE can track the ideal force. Simulation analysis is conducted to validate the effectiveness of the proposed ASES. Simulation results show that compared to passive suspension, ASES can fully utilize the suspension’s travel to consume more energy during the main stages of impact, and the peak impact acceleration of ASES has been reduced by 42.25%. The proposed wave adaptive vessel equipped with electromagnetic suspension has practical application potential.
