모드해석을 통한 마운트 공진회피 설계

Abstract

This paper provides how to solve the problems analytically and experimentally that occur for testing the water injection pump under development. First of all, water injection pump, based on shaft system dynamic analysis, is verified by measuring the behavior of the shaft system. After the water injection pump is measured, the structural resonances which can cause excessive noise, degradation the equipment life and malfunction are found. Therefore, by changing the structural design, the resonance should be avoided. Application of the design variables to the experimentally resonance avoidance is difficult. So analytically, with application of the design variables, the design will be changed with mode analysis using FEM.
