大型船用浮筏气囊隔振系统容易产生弹性变形，不仅会导致筏上设备产生相对位移，危及设备运行安全，还会造成气囊载荷分布不均，降低控制系统对复杂工况的适应性。本文建立某船舶浮筏隔振装置模型，提出一种基于位移参数识别的筏架弹性变形判别方法，并根据此方法分析设备分布和气囊支撑方式对筏架弹性变形和控制系统的影响，最后在试验平台上进行验证。研究成果可为浮筏气囊系统设备分布和气囊布置方案设计提供新的思路。
The air spring vibration isolation system of large marine floating raft generate elastic deformation easily, which will not only result in relative displacement between devices on raft, affecting operational safety, but also cause uneven load distribution of air spring, reducing the adaptability of the control system to complex working conditions. Firstly, a model of floating raft isolation device for a ship is established in this paper. Secondly, a method for determining elastic deformation of raft is proposed based on displacement parameter identification. Then, the influence of equipment distribution and air spring support mode on the elastic deformation of raft and the control system is analyzed based on this method. Finally, the above research contents are partially verified on the test platform. The research results can provide a new idea for the design of the equipment distribution and air spring arrangement of the raft air spring system.
