A Study on Influence of High Pressure Hose on Automotive Power Steering Interior Noise Using Frequency Analysis

유압식 자동차 동력조향장치 실내소음에 고압호스가 미치는 영향의 주파수 분석을 통한 연구

A high pressure hose having tuning cables, called Resonator hose' is frequently used to attenuate pressure ripple generated by the pump fur reducing the vehicle interior noise. A number of studies have been conducted on the resonator hose and its analytical models. However, there are few studies which deal with the influence of resonator hose on vehicle interior noise because the most of studies focused on transmission loss of the resonator hose. (omitted)
