船舶非线性主动减振系统对于提高船舶在风浪作用下的安全性、稳定性有非常重要的作用，同时可以降低舰船结构的冲击和疲劳损伤。相对于被动减振系统，主动减振通过控制器监测船舶的运动状态和环境特性，通过调节系统的控制参数实现减振。本文详细介绍船舶非线性主动减振系统的硬件功能原理和控制器原理，针对减振系统在突变冲击激励下的动力学响应进行分析，并结合试验台进行了船舶非线性主动减振系统的减振性能测试。
The nonlinear active vibration reduction system of ships plays a very important role in improving the safety and stability of ships under wind and waves, and can reduce the impact and fatigue damage of ship structures. Compared to passive vibration reduction systems, active vibration reduction monitors the motion status and environmental characteristics of ships through controllers, and achieves vibration reduction by adjusting the control parameters of the system. This article provides a detailed introduction to the hardware functional principles and controller principles of a nonlinear active vibration reduction system for ships. The dynamic response of the vibration reduction system under sudden impact excitation is analyzed, and the vibration reduction performance of the ship's nonlinear active vibration reduction system is tested on a test bench.
