冲击隔离系统的作用是在船体和电子设备之间添加隔离装置,降低电子设备受到的船体冲击载荷,对于保障船舶电子设备的安全运行有重要的作用。传统的冲击隔离系统采用弹簧等机械阻尼元件进行冲击隔离,这种隔离系统只能被动减振,本文介绍一种磁流变智能阻尼器技术,在此基础上设计检测机械设备的冲击隔离系统,通过建立船体与隔离系统的动力学模型,在Matlab中完成了较准确的冲击隔离系统的振动响应仿真。
The function of impact isolation system is to add isolation devices between the hull and electronic equipment to reduce the hull impact load on electronic equipment, which plays an important role in ensuring the safe operation of ship electronic equipment. The traditional impact isolation system uses mechanical damping elements such as springs for impact isolation, which can only passively reduce vibration. This paper introduces a magnetorheological intelligent damper technology. On this basis, the impact isolation system for detecting mechanical equipment is designed. By establishing the dynamic model of ship hull and isolation system, The vibration response simulation of impact isolation system is completed in Matlab.
