一种潜液泵的模态分析及支撑形式改进

摘要

In order to improve the quality and performance of the diving liquid pump, the static strength and modal analysis of a type of diving liquid pump was carried out by finite element method.The support method of concentric pipes was improved according to the sympathetic vibration of the diving liquid pump.The numerical results showed that the sympathetic vibration ranks and adjective effect are reduced in a certain extent after improving the support method.%为提高潜液泵的质量和性能,运用有限元法对某潜液泵进行静强度计算和模态分析,分析液泵共振,改进同心管结构的支撑形式.结果表明,改进支撑以后减少了共振阶次,在一定程度上缓解了共振带来的不良影响.
