abstract = "This paper introduces the mechanism of vibration transmission and sound radiation of a simplified automobile panel model, reveals the sound and vibration characteristics of the body panel structures, and provides a theoretical support to solve the low frequency panel vibration and booming
problems. In this paper, a vehicle liftgate is simplified as a simply-supported rectangular plate. And an analysis model combining the plate and a lumped-mass damper is established. By theoretical analysis and finite element analysis, the influence of the mass damper on the characteristics
of the vibration and noise radiation is studied. The paper also analyzes the mechanism of the low frequency interior booming, and provides a control method to attenuate the liftgate vibration and sound radiation by tuning the mass damper. The vehicle testing is consistent with the analysis
result, and the vehicle booming is significantly attenuated. The simplified model that is proved by the testing provides a guideline for vehicle interior booming control.",
