4000 kW救助船泵基座减振研究及设计

Vibration Damping Design of Pump Base for 4000 kW Rescue Vessel

本文应用模态分析方法,以4000 kW救助船应急消防泵为例,研究四种常用型式的泵基座的固有频率。结果表明,圆柱法兰基座和井字形拼板基座具有良好的抗振性能,增加基座腹板厚度、降低基座高度,可有效提升抗振性能。

Taking the emergency fire bump of the 4000 kW rescue ship as an example,the natural frequencies of four common types of pump base are studied by means of modal analysis.The results show that the cylindrical flange base and the wellbore split plate base have good anti-vibration performance,and the anti-vibration performance can be effectively improved by increasing the thickness of the base web and reducing the base height.
