| 摘 要： | 根据某船舶设计中提出的减小空压机组的振动传递、降低水下机械噪声的要求,针对机组所具有的振动激励特性,进行了隔振浮筏装置的设计.利用有限元分析软件ANSYS,建立了空压机组浮筏装置在陆上台架以及装船后的动力学分析模型,计算得到了隔振系统的各阶模态,分析了系统的振动传递特性以及对于冲击的响应特性,探讨了提高船舶设备隔振与抗冲击性能的途径.

| Abstract: | With the demand of reducing vibration and underwater noise caused by the air compressor, the design of an isolation device with the floating raft is described based on the comprehension of the excitation source. FEA models of the vibration isolation system in case of test bank status and installation in ship were established separately by means of the software ANSYS. The vibration modes, the transmission characteristics of the system as well as the shock response were analyzed.The way to improve the isolation efficiency and the anti-shock properties are explored. |
