진동-음향 연성계의 모드 특성에 대한 이론적 고찰

In case that side doors in a passenger vehicle are vibrating and the frequencies of those are close to the acoustic frequency of passenger cavity, the acoustic-structural coupling between the passenger cavity and side doors must be considered to identify the coupled system. This system is modeled as 1-D coupled model and the characteristics of coupled frequencies and modes are examined closely.
