To investigate the collision dynamics of a marine rotating machinery integrated with an airbag-raft-limiter system under the influence of heaving motions, a dynamic model of an asymmetric system incorporating a limiter was developed. This model took into account the effect of the ship heaving motion and the limiter gap on the coupled airbag-raft-limiter system. The equations of motion were given dimensionless treatment to facilitate computational analysis. The study examined the influence of rotor speed, heaving amplitude, and limiter gap on the system’s dynamics utilizing nonlinear dynamics analysis techniques including phase diagrams, spectral responses, and energy trajectory diagrams. The findings indicate that an increase in heaving amplitude leads to collisions between the system and the limiter, causing a significant amplitude decrease while triggering a transition of motion from quasi-periodic state to chaotic state. Additionally, the collision alters the energy trajectory of the system, moving from a uniform distribution towards the collision zone.

为了研究垂荡作用下船用旋转机械耦合浮筏-气囊-限位器系统的碰撞特性,针对船舶垂荡作用及限位器间隙对船用旋转机械耦合浮筏-气囊系统的影响,建立垂荡运动下具有限位器的非对称系统的动力学模型,并对运动方程进行无量纲化处理。利用相图、频谱响应和能量轨迹图等非线性动力学分析方法,研究转子转速、垂荡幅值和限位器间隙对系统动力学特性的影响。研究发现:在垂荡作用下的船用旋转机械耦合浮筏-气囊-限位器系统中,随着垂荡幅值的增加,系统与限位器发生碰撞,导致振幅大幅度减小,但运动状态从拟周期过渡到混沌;碰撞使系统能量轨迹由均匀分布向碰撞区域运动。
