Design for Resonance Avoidance of Mount Through the Modal Analysis

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.

Enhanced Design of Sunroof System through Parametric Study Considering Vibration Phenomenon during Vehicle Operation

“…Their modal analysis anticipated its vibration characteristics; this was achieved through constructing a threedimensional finite element model and comparing it with the results obtained from modal testing. Lee et al [10] investigated mount resonance avoidance by analyzing the dynamic characteristics of a water injection pump system. After evaluating the potential resonance at the 7X component derived from axial dynamic characteristic analysis, experimental measurements at approximately 107 Hz confirmed the casing resonance.…”
