硝酸四合一机组底座的谐响应分析

Harmonic Response Analysis on Base Plate of Nitric Acid Machine Group with Four Machines

应用有限元方法基本原理,利用有限元分析软件(ANSYS),对硝酸四合一机组底座进行模态分析和谐响应分析,分别得到了沿机组底座的虚拟轴x、y和z向的位移谐响应曲线。得出了机组底座平稳运行时,机组底座的谐响应规律及其特点,为改善机组底座的动态特性提供了一定的参考依据。

Basic principle of finite element method and finite element analysis software ANSYS are used to conduct mode analysis and harmonic response analysis for the base plate of nitric acid machine group with four machines, as a result, displacement harmonic response curves along the virtual axes X, Y ＆ Z of the base plate haye been obtained respectively, and harmonic response＇s regular pattern and characteristics have been obtained as well during the base plate is in stable running, which provide certain reference basis to improve the dynamic characteristics of the base plate.
