Cross Mobility Computation of Supporting Structures for Pumps

摘要: 导纳是结构振动噪声研究的重要内容。本文以泵类设备支承结构的试验模型为计算实例,利用有限元法和统计能量分析计算该模型的传递导纳,并与试验值进行比较,以验证该方法对导纳特性预报的有效性。

Abstract: Mobility is one important topic in the research of structure vibration and noise.In this paper,cross mobility of supporting structures for pumps is calculated with finite element method（FEM） and statistical energy analysis（SEA）.The validity of predicting the mobility of supporting structures with FEM and SEA is evaluated by comparing the values from experiments,and it shows that this method is effective in the prediction of mobility characteristics.
