Investigation of a Cabin Suspended and Articulated Rescue Vessel in Terms of Motion Reduction

To solve the problem that small rescue vessels are seriously affected by waves when working at sea, which causes damage to crew and equipment, a catamaran with suspended articulated cabin is designed. The multi-body dynamic model of whole vessel based on SimMechanics built, prototype tested water. correctness verified three aspects roll motion, pitch heave motion platform. platform simulated under conditions bow large waves, RMS value vertical acceleration taken as response target analyze influence suspension system parameters vessel. has good buffering reduction effects various conditions, it an obvious effect larger amplitude wave impact, more effect. reduces angle waves.
